Best Marketing Automation Software for Small Business in 2026
Short answer: ActiveCampaign is the best marketing automation software for a small business in 2026, starting at $15/mo for 1,000 contacts on annual billing, with a visual workflow builder most SMB teams outgrow slowly. Mailchimp is the easiest free start, covering up to 250 contacts at no cost. Brevo and MailerLite are the cheapest paid seats, at $9/mo and $12/mo. HubSpot fits once you want a CRM in the same login. Nobody on this list should pay a five-figure onboarding fee to send a welcome email.
10 platforms compared on what a small list actually costs at 1,000, 5,000 and 10,000 contacts, with prices checked on vendor pages in September 2026.
A small business does not need Marketo. It needs a welcome sequence, an abandoned-cart nudge if it sells online, a lead score simple enough that one person can read it, and a bill that does not double the moment the list crosses 1,000 names. That last part is where most of this category trips small buyers: the price on the homepage is usually the cheapest contact band, and the real cost only shows up once you plug in your actual list size.
This guide ranks 10 platforms for that buyer specifically, not the mid-market or enterprise version of the same question. Toolradar data: 32% of the marketing automation tools we track offer a free or freemium plan, and 66% charge from the first contact, out of 346 tools in the marketing automation category. A free row in that count is often a newsletter tool with no branching automation, so read the automation tier, not the free badge, before you commit a list.
One disclosure up front: Dupple's own newsletters run on beehiiv, not on any tool ranked here, so this list has no stake in which email platform you choose. How we chose: these 10 were ranked for a US small business pricing a first or second marketing automation tool, at contact bands a small list actually hits, with prices checked on vendor pages in September 2026. The method is on how we rate.

A small business ready to build more than one branching automation sequence.
- Pro: Starter covers email campaigns and a basic automation builder at 1,000 contacts on annual billing. Plus, the tier most small businesses actually need for branching workflows and lead scoring, costs roughly three times as much at the same 1,000 contacts.
- Pro: Pro moves to $79/mo at 1,000 contacts and adds premium ecommerce integrations and more advanced segmentation, useful once a store is generating real cart-abandonment volume.
- Pro: ActiveCampaign lists no setup fees and includes free migration and onboarding from a previous platform, so a small team is not paying a second bill just to move its list over.
- Con: There is no free plan, only a 14-day trial, so a business that wants to test automation for months without paying has to look at Mailchimp, MailerLite or Omnisend instead.
- Con: The interface asks more of a first-time user than Mailchimp or MailerLite. A one-person marketing team with no automation experience will spend real hours in the workflow builder before the first sequence ships.
Mailchimp
- 4.5 on Capterra (17,598 reviews)
- 4.3 on G2 (12,988 reviews)
- 2.6 on Trustpilot (1,411 reviews)
A brand-new business collecting its first few hundred email signups.
- Pro: Free covers up to 250 contacts and roughly 500 sends a month, no credit card commitment beyond that cap. It is still the most recognized name in the category, which matters when handing the account to a contractor or new hire.
- Pro: Essentials starts at $13/mo and Standard follows at a higher monthly rate, both priced from a 500-contact base, with Standard adding customer journey automation and A/B testing on top of the template editor most reviewers still rate as the category's best. The Mailchimp profile has the tier-by-tier detail.
- Pro: Premium starts at $350/mo, built around a 10,000-contact base, and adds phone support and advanced segmentation for a business that has genuinely outgrown the small-list stage.
- Con: Automation branching is thinner than ActiveCampaign or GetResponse at an equivalent price. A small business planning more than a welcome sequence and a re-engagement flow will hit the ceiling faster here than on ActiveCampaign, the top pick in this guide.
- Con: The jump from the 250-contact free plan to a paid tier arrives quickly for any business actively building a list from a website, and Essentials does not include the automation depth Standard does.
Mailchimp was once the default email marketing tool for small businesses, and its free tier was legendary.
Watch out
ALL contacts count: subscribed, unsubscribed, non-subscribed, and 'cleaned' contacts all count toward your plan limit. You pay for contacts who unsubscribed last year unless you manually archive them. This inflates costs by 20-40% for most lists
A small business mailing frequently on a tight monthly budget.
- Pro: Free has no contact cap, just a ceiling of 300 emails a day once the account is approved to send, which suits a small business with a loyal, frequently-mailed list better than a contact-capped free plan.
- Pro: Starter is Brevo's cheapest paid seat, and Standard, the first tier with real marketing automation and unlimited multi-step workflows, is $18/mo, both well under GetResponse or ActiveCampaign's equivalent automation tier.
- Pro: Brevo bundles email, SMS and WhatsApp sending in one account, so a small business testing a second channel does not need to add another vendor for that alone.
- Con: Automation depth on Standard still lags ActiveCampaign's branching logic, and the jump to Professional, $499/mo, is a large step up in budget just to turn on contact scoring.
- Con: Deliverability on the free tier has been reported as inconsistent by users pushing close to the daily send cap, so a business relying entirely on the free plan should watch inbox placement closely.
Brevo's pricing is quite competitive, especially at the entry level.
Watch out
Removing branding is an add-on
A small business or solo operator who wants automation without a steep learning curve.
- Pro: Free covers 250 subscribers and 2,500 monthly emails with 3 automations, 1 website and 1 landing page, enough to test the platform before committing a card. The full plan breakdown is on MailerLite's own pricing page.
- Pro: Comfort is $12/mo billed monthly, or $10.80/mo billed annually, up to 500 subscribers, and raises the automation count to 50 active automations and 10 websites and landing pages, a meaningful jump for a small budget.
- Pro: Power is $25/mo billed monthly, or $22.50/mo billed annually, up to 500 subscribers, and removes the automation and landing-page caps entirely and adds unlimited user seats, useful once a second person joins the marketing effort.
- Con: MailerLite is priced on usage, not feature gates, so a fast-growing list moves the monthly price even if the business never adds a new feature. Budget for that growth, not just the entry number.
- Con: Reporting and segmentation stay basic next to ActiveCampaign or GetResponse, which matters once a business wants to segment by more than a simple tag or open rate.
Mailerlite's pricing is very fair and generous, especially with its robust free tier.
A small business that wants landing pages, funnels and automation in one subscription.
- Pro: Starter is $19/mo at 1,000 contacts, billed monthly, or $15.58/mo billed annually, and includes unlimited email sends, a landing page builder and one custom automation workflow. The full tier comparison is on GetResponse's own pricing page.
- Pro: Marketer, at $59/mo for the same 1,000 contacts, removes the one-workflow limit entirely, adds abandoned-cart recovery and advanced segmentation, and is the tier most small ecommerce sellers actually need.
- Pro: Creator, at $69/mo, adds a website builder and webinar hosting for up to 500 students, useful for a small business that also teaches or demos its product live.
- Con: Starter's single automation workflow is a real limit, not a marketing figure. A business planning even two separate sequences, a welcome flow and a cart-recovery flow, needs Marketer, tripling the entry price.
- Con: There is no free plan, only a 30-day trial, so a business that wants to test automation without a deadline should start with Mailchimp, MailerLite or Omnisend instead.
It's best for small to medium businesses and creators seeking an all-in-one marketing platform.
Watch out
18% discount requires annual billing
HubSpot Marketing Hub
- 4.4 on G2 (13,374 reviews)
- 4.5 on Capterra (4,455 reviews)
- 4.3 on TrustRadius (669 reviews)
- 1.8 on Trustpilot (613 reviews)
- 4.1 on PeerSpot (39 reviews)
A small business that wants marketing and its contact database in one product.
- Pro: Starter pairs with HubSpot's free CRM, so a small business gets a contact record and an email tool in the same login without paying for Professional, at 1,000 marketing contacts included. The HubSpot profile covers the wider suite.
- Pro: Non-marketing contacts, records you store but never email, are free and do not count against the marketing-contact limit, which helps a business with a large sales list but a smaller active newsletter.
- Pro: For a business that outgrows Starter, Professional starts at $890/mo for 3 seats and 2,000 marketing contacts and turns on lead scoring, though that tier is built for a bigger team than most readers of this guide.
- Con: Starter does not include lead scoring or the deeper automation branching Professional turns on, and Professional's $890/mo base plus a required $3,000 one-time onboarding fee is a large jump for a small business budgeting month to month.
- Con: The per-seat pricing model means a second or third person on the account adds to the bill in a way flat-priced tools like Keap or MailerLite's Power plan do not.
HubSpot's pricing is the most complex in SaaS, 7 Hubs, 4 tiers each, per-seat AND per-contact charges, plus mandatory onboarding fees.
Watch out
Marketing contacts vs non-marketing contacts: HubSpot only charges for 'marketing contacts' (those you email, use in ads, or include in workflows). But the distinction is confusing, and accidentally including contacts in a marketing email converts them to paid marketing contacts with no undo
A small ecommerce store that needs abandoned-cart and post-purchase automation.
- Pro: Free covers 250 contacts, 500 monthly emails and 500 web push notifications, with core automation, segmentation and forms included even on the free tier. The full feature list is on Omnisend's own pricing page.
- Pro: Standard is $16/mo list for 500 contacts and 6,000 monthly emails, billed monthly; Omnisend runs a 30%-off first-3-months promo at $11.20/mo, reverting to the $16/mo list rate after that. Standard adds AI-assisted forms and reporting, and every paid tier includes cart-recovery automation by default rather than as an add-on.
- Pro: Pro is $59/mo list for 2,500 contacts with unlimited monthly emails, billed monthly; the same 30%-off first-3-months promo brings it to $41.30/mo before reverting to the list rate. Pro adds dynamic content and send-time personalization, features aimed specifically at ecommerce conversion rather than general newsletters.
- Con: The contact bands are smaller than the automation-first competitors at a similar price. Pro's 2,500-contact allowance is roughly a third of what ActiveCampaign's Pro tier covers at $79/mo, so a fast-growing list moves the price quickly.
- Con: Omnisend is built for ecommerce specifically. A service business with no online store gets little benefit from its strongest feature set and should look at ActiveCampaign or GetResponse instead.
Omnisend's pricing is fair, especially with a generous free tier for up to 250 contacts.
A small business where the same one or two people sell and market.
- Pro: $299/mo, or $2,988 billed annually, includes the whole platform rather than feature-gated tiers: lead scoring, a sales pipeline, landing pages and email automation all sit on that one subscription. The full breakdown is on Keap's own pricing page.
- Pro: Two user licenses are included, and a third is $39/mo, a known cost rather than a jump to a new named edition the way HubSpot's per-seat model works.
- Pro: US text marketing is bundled starting with a first tier of 500 messages and 100 voice minutes a month, useful for a small business that already texts customers about appointments or orders.
- Con: Implementation services are required, and the fee is not published on the pricing page, so the flat monthly software line is not the full year-one bill. Ask for that number before signing the annual term.
- Con: Annual customers who cancel early pay a $299 termination fee, and the request has to start at least 10 days before the next invoice, which makes Keap a bigger commitment than the month-to-month tools on this list.
It's best for established small businesses with higher budgets prioritizing an all-in-one solution.
Watch out
Overage fees for additional contacts
A solo creator or content-led small business growing a subscriber list before it monetizes.
- Pro: Free covers up to 10,000 subscribers with unlimited landing pages, forms and email broadcasts, a far higher free ceiling than Mailchimp's 250 or MailerLite's 250. The full plan comparison is on Kit's own pricing page.
- Pro: Creator, $33/mo at 1,000 subscribers, adds unlimited visual automations, email sequences and A/B testing, and a 14-day trial requires no credit card to start.
- Pro: Pro, $66/mo at 1,000 subscribers, adds subscriber engagement scoring and an insights dashboard, useful for a creator business trying to see which content drives the most signups.
- Con: Kit is built for creators first: e-commerce automation and general small-business features like a bundled CRM are not the product's focus, and pricing scales quickly with subscriber count past the free tier.
- Con: Design and template tooling are less polished than Mailchimp's, which matters for a small business that wants a more branded, visual newsletter rather than a plain-text-style creator email.
Kit's pricing is quite generous, especially with its robust free 'Newsletter' tier supporting up to 10,000 subscribers.
A budget-conscious small business that mostly sends newsletters, not complex journeys.
- Pro: Free covers up to 2,000 contacts and 6,000 emails a month with 5 users, the highest free-tier contact allowance on this entire list. The full plan detail is on Zoho Campaigns' own pricing page.
- Pro: Standard and Professional both undercut every other paid tier on this list on a per-contact basis; check current USD pricing on Zoho's own pricing page, since Zoho localizes price by region and the exact figure depends on billing term.
- Pro: Professional adds contact scoring, advanced workflows and abandoned-cart tracking at 1,000 contacts, still a fraction of what ActiveCampaign or GetResponse charge for similar features.
- Con: Automation stays at basic drag-and-drop workflows even on Professional, well behind ActiveCampaign's branching builder, so a business planning multi-path journeys will outgrow this platform faster than the price suggests.
- Con: Zoho Campaigns is best known as part of the wider Zoho suite. A business not already using other Zoho products gets less of the integration benefit that makes the low price a stronger deal.
The 'Kostenlos' tier for Zoho Campaigns is quite generous, offering 6,000 emails and 2,000 contacts for free, which is more than many competitors provide in their free plans.
Watch out
Overage fees for exceeding email/contact limits
Other Marketing Automation tools worth considering
More published tools from our Marketing Automation category, ordered by our category ranking. They are not part of the editorial picks above.
What marketing automation software for a small business actually means
Marketing automation software sends the right message when a contact does something, a signup, a purchase, an abandoned cart, without a person clicking send each time. For a small business the job is narrower than the enterprise version: one welcome sequence, one re-engagement flow, maybe one cart-recovery flow, run by an owner or a single marketer, not a marketing-ops team.
That narrower job changes what "best" means. A platform built for an enterprise buying committee (Marketo, Eloqua, Salesforce's Account Engagement), the kind ranked in the B2B marketing automation guide, prices in org fees and quote-only tiers that a five-person company will never justify. A platform built for a small list (Mailchimp, MailerLite, Brevo, Kit) prices per contact band starting at a few hundred names, and the automation depth scales with the plan, not the seat count.
The tools on this list range from send-first email platforms, closer to the picks in the email marketing software guide, to automation-first platforms where a contact record can trigger a branching, multi-step journey (ActiveCampaign, GetResponse). A few (HubSpot, Keap) bundle a small CRM into the same login, which matters if the same person is also chasing the sale.
Why the homepage price is not the small-business price
Every platform on this page advertises its cheapest number on the homepage, and that number is almost always the smallest contact band with the fewest automation features turned on. ActiveCampaign's entry Starter tier and its next-step Plus tier are both priced at 1,000 contacts, but only Plus opens the automation and segmentation most small businesses actually came for. Mailchimp's free plan caps at 250 contacts, a list size many small businesses pass in the first month of collecting emails on a website.
The second trap is the jump between bands. GetResponse's Marketer plan and Zoho Campaigns' Professional plan are both priced at the same 1,000 contacts, yet sit roughly six times apart, a gap wide enough that "marketing automation software" is really several different budgets wearing one category label. Read the price at your actual list size, not the number under the plan's name, before you compare two tools.
A small business also pays for automation depth it may never use. HubSpot's Marketing Hub Starter sends email and hosts forms but keeps lead scoring off; that only turns on at Professional, a tier priced for a bigger team than most readers of this guide, with a required one-time onboarding fee bundled into the base.
Key Features to Look For
How the contact meter works (Essential)
Every platform here bills on stored contacts, not seats, so the number that matters is your list size at signup, not the plan name. ActiveCampaign, GetResponse and HubSpot all publish their headline price at 1,000 contacts specifically, which is why that band is the fair comparison point across this guide. Zoho Campaigns and Omnisend both quote a much lower number at 1,000 contacts than the automation-first tools, because their automation is thinner.
What the free plan actually includes (Essential)
Mailchimp's free plan stops at 250 contacts and 500 sends a month. Kit's free plan goes to 10,000 subscribers but ships no paid automations beyond a basic sequence. Omnisend and MailerLite both cap free at 250 subscribers with a few thousand monthly sends. Brevo's free plan has no contact cap at all, just a 300-emails-a-day ceiling, which suits a business with a small but frequent send cadence better than a business building a large list slowly.
Automation workflow depth (Essential)
A welcome sequence is table stakes; branching logic based on a click, a tag or a purchase is the feature that separates an automation platform from a send tool. ActiveCampaign's automation builder is the deepest on this list at small-business pricing. GetResponse locks unlimited automation workflows behind its Marketer tier; the cheaper Starter tier includes exactly one custom workflow. Zoho Campaigns and Mailchimp both offer basic drag-drop automation, but neither branches as many ways as ActiveCampaign or Keap.
Ecommerce triggers (Important)
Abandoned-cart recovery and post-purchase flows matter only if the business sells online, but when they do they are usually the highest-ROI automation in the account. Omnisend was built around this trigger set specifically. GetResponse adds abandoned-cart recovery starting on its Marketer tier. ActiveCampaign and Klaviyo-style ecommerce depth is not the strength of Mailchimp, Kit or Zoho Campaigns, which are closer to newsletter tools with automation added on top.
Landing pages and forms included (Important)
A small business without a developer often builds its signup forms and simple landing pages inside the email platform rather than the main website. MailerLite includes 1 website and 1 landing page even on its free plan, rising to 10 on Comfort. GetResponse bundles a landing page builder from its Starter tier. Kit's free plan includes unlimited landing pages and forms, which is unusual for a free tier and a real reason creators default to it.
CRM or pipeline in the same login (Important)
HubSpot and Keap both fold a small CRM into the subscription, so the same login tracks the email sequence and the deal, the same job covered in more depth in the CRM software guide. Keap is built for this from the ground up, at its flat monthly rate including 2 user seats, with implementation services required on top. HubSpot's free CRM pairs with Marketing Hub Starter for a lighter version of the same idea, without the deal-pipeline depth Keap ships by default.
Onboarding and setup cost (Nice to have)
Most platforms on this list have no onboarding fee: you sign up and start building. Two do not. HubSpot charges $3,000 once for Marketing Hub Professional and $7,000 once for Enterprise, a fee a five-person company rarely needs to pay because Starter covers the same job at a fraction of the price. Keap requires implementation services with a fee its pricing page does not publish, so ask for that number before you sign the annual contract.
What to check before you pick one
Price the plan at your real list size, not the smallest band on the homepage. ActiveCampaign, Mailchimp, HubSpot and GetResponse all publish different numbers as the list grows past 1,000 contacts.
Confirm which tier turns automation on, not just email sending. GetResponse's cheapest tier includes exactly one workflow; the unlimited-workflow tier is $59/mo, a different budget entirely.
If the business sells online, shortlist Omnisend or GetResponse for cart recovery before a generic newsletter tool that bolts automation on as an afterthought.
If one person runs sales and marketing, weigh Keap or HubSpot's bundled CRM against running two separate logins and syncing them yourself. If HubSpot's per-seat pricing is the objection, see HubSpot alternatives.
Ask about onboarding and implementation fees before you sign. HubSpot's Professional and Enterprise tiers and Keap's setup both carry costs that never show up on the plan-comparison table.
Evaluation Checklist
Price every finalist at your actual contact count, not 1,000, before you decide. GetResponse and ActiveCampaign both roughly quadruple in price between their entry tier and their full-automation tier.
Confirm the free or entry tier includes real automation branching, not just a single welcome email. GetResponse's Starter tier ships exactly one workflow.
If you sell online, ask specifically about abandoned-cart and post-purchase automation. Omnisend and GetResponse's Marketer tier include it; Mailchimp, Kit and Zoho Campaigns treat it as a lesser feature.
Ask HubSpot and Keap for the full first-year cost, including onboarding or implementation fees, before comparing their monthly number to a platform with no setup fee.
Test the automation builder with your own welcome sequence before you commit a year of billing. A visual builder that takes an afternoon to learn on ActiveCampaign can take a week on a less intuitive one.

Mistakes to Avoid
- ×
Comparing Mailchimp's free plan directly against ActiveCampaign's entry tier without noting that Mailchimp's free plan caps at 250 contacts, a size many small lists pass within weeks.
- ×
Buying GetResponse's Starter tier expecting the multi-step automation shown in a demo, when that depth sits one tier up, on Marketer.
- ×
Signing HubSpot's Professional tier for lead scoring without budgeting the required onboarding fee that ships with it.
- ×
Treating Keap's flat monthly rate as the full first-year cost when implementation services, required and unpriced on the page, are billed on top.
- ×
Picking an ecommerce-first tool like Omnisend for a service business with no cart to recover, or a general newsletter tool like Mailchimp for a store that needs abandoned-cart automation from day one.
Expert Tips
- →
Start on the cheapest tier that includes real automation branching, not the cheapest tier that only sends email. On GetResponse that means Marketer, not Starter, even though Starter is the number most people compare first.
- →
If your list is under 1,000 contacts, test MailerLite's or Omnisend's free plan before paying for anything. Both include basic automation at no cost, which most small businesses never actually get to in a trial.
- →
Ask every finalist for its price at 5,000 and 10,000 contacts before you sign, not just at 1,000. A business planning to grow its list should model the tier it will be on in a year, not the one it starts on.
- →
If the same person sells and markets, price Keap's flat monthly rate against a separate email tool plus a free CRM before assuming the bundle is cheaper. It often is not for a very small list.
- →
Keep implementation and onboarding fees in a separate line in your budget. HubSpot and Keap both carry them, and neither shows up in the monthly number most comparison tables print.
Red Flags to Watch For
-
An entry price advertised at a contact count your list already exceeds. Compare at 1,000, 5,000 or 10,000 contacts, whichever matches your real list, not the smallest number on the page.
-
A tier that sends email but keeps branching automation locked, the trap on GetResponse's Starter and HubSpot's Marketing Hub Starter.
-
An unpublished implementation or onboarding fee, the case on Keap and on HubSpot's Professional and Enterprise editions, that turns a monthly number into a much larger year-one bill.
-
A platform chosen for its ecommerce automation by a business that has no online store, or vice versa, a general newsletter tool chosen by a store that actually needs cart recovery.
The Bottom Line
Buy ActiveCampaign when a small business wants the deepest automation builder it can afford, entering at its Starter tier and stepping up to Plus once full branching and segmentation matter. Buy Mailchimp when the business needs a free start under 250 contacts and values brand recognition over automation depth.
Use Brevo or MailerLite when the budget is the deciding factor and automation can stay simple. Use GetResponse or Omnisend when webinars, funnels or ecommerce triggers are part of the job. Use HubSpot or Keap when the same login should also hold the sales pipeline, and budget their onboarding or implementation fees separately from the monthly price. Use Kit when the business is creator-led and growing a list before it monetizes, and Zoho Campaigns when the goal is the lowest cost per contact and the automation can stay basic.

Frequently Asked Questions
What is the best marketing automation software for small business in 2026?
ActiveCampaign is the best default for a small business in 2026 that wants real automation depth on a small-business budget. Starter is $15/mo for 1,000 contacts, and Plus, the tier most small businesses actually need for branching workflows, is $49/mo at the same contact count. Mailchimp is the better starting point for a business that wants a free plan first, covering up to 250 contacts at no cost.
Brevo and MailerLite are the cheapest paid entries. HubSpot fits once a bundled CRM matters, and Keap fits when the same one or two people run sales and marketing together.
How much does marketing automation cost for a small business?
At 1,000 contacts, published September 2026 USD entry prices range from Zoho Campaigns Standard, the cheapest paid tier on this list (check current pricing on Zoho's site), up to $79/mo on ActiveCampaign Pro. ActiveCampaign Starter is $15/mo, Brevo Starter is $9/mo, MailerLite Comfort starts from $12/mo, GetResponse Starter is $19/mo, and HubSpot Marketing Hub Starter is $20/mo per seat.
The tier that actually turns on branching automation often costs more than the entry number: ActiveCampaign Plus is $49/mo, GetResponse Marketer is $59/mo, and HubSpot Professional, where lead scoring turns on, is $890/mo for 3 seats plus a $3,000 one-time onboarding fee.
Is there a free marketing automation tool for small business?
Yes, several. Mailchimp and Omnisend are both free up to 250 contacts, MailerLite is free up to 250 subscribers, Kit is free up to 10,000 subscribers, Zoho Campaigns is free up to 2,000 contacts, and Brevo's free plan has no contact cap at all, just a limit of 300 emails a day.
ActiveCampaign, GetResponse and Keap do not offer a free plan, only a trial: 14 days on ActiveCampaign, 30 days on GetResponse, and a capped trial on Keap that sends at most 25 emails.
Mailchimp or ActiveCampaign for a small business?
Choose Mailchimp when the business is brand new, the list is under 250 contacts, and a free plan matters more than automation depth. Choose ActiveCampaign when the business already knows it wants branching workflows, lead scoring and deeper segmentation, features that stay basic on Mailchimp even at its Standard tier.
A business that starts on Mailchimp's free plan and later wants ActiveCampaign's automation depth can migrate; ActiveCampaign lists free migration and onboarding from a previous platform on its pricing page. See the full matchup at Mailchimp vs ActiveCampaign.
What is the cheapest marketing automation software for a small business?
Zoho Campaigns is the cheapest paid option per contact at 1,000 contacts on its Standard tier, and its free tier covers up to 2,000 contacts; check current USD pricing on Zoho's own pricing page, since it varies by billing term. Brevo's Starter plan and MailerLite's Comfort plan are the next cheapest paid tiers.
The tradeoff is automation depth: Zoho Campaigns keeps automation to basic drag-and-drop workflows even on its higher Professional tier, so a business planning multi-path journeys should budget for ActiveCampaign or GetResponse instead.
HubSpot or Keap for a small business that sells and markets from the same team?
Choose Keap when the whole platform, pipeline, scoring, email and landing pages, should sit on one subscription without feature-gated editions, and when implementation help is welcome. A wider list of HubSpot-priced options sits in the HubSpot alternatives guide. Choose HubSpot Marketing Hub Starter when a lighter free CRM paired with a cheap marketing tier fits the budget better than Keap's flat rate.
Both carry costs outside the headline number: Keap requires implementation services at an unpublished fee, and HubSpot's Professional tier, where deeper CRM and scoring features live, adds a required $3,000 onboarding fee on top of its $890/mo base.
Do I need marketing automation if I am just starting out?
A welcome sequence and a re-engagement flow for inactive subscribers are worth setting up even at a few hundred contacts, and every free plan on this list, Mailchimp, MailerLite, Omnisend, Kit, Brevo and Zoho Campaigns, includes basic automation at no cost. Start there before paying for a platform like ActiveCampaign or GetResponse built around automation depth most new lists will not use yet.
Upgrade once the business needs branching logic, like sending a different follow-up based on whether someone clicked a link or bought a product, because that is the feature every entry-level free plan keeps simplest.
