MillionVerifier FAQ
How does MillionVerifier help reduce bounce rates before sending campaigns?
MillionVerifier verifies email lists before you send campaigns, which reduces bounce rates and protects your sender reputation. It offers a single email checker, bulk list verification via CSV/TXT/XLSX upload, and a REST API for real-time verification. By catching invalid or risky emails in advance, you avoid bounces that can harm your deliverability.
Which teams or users benefit most from using MillionVerifier?
Marketers and businesses that send email campaigns benefit most from MillionVerifier, especially those who want to reduce bounce rates and protect sender reputation. It suits teams that need to verify lists before sending, whether they handle small batches or large volumes. The service is also useful for developers who want to integrate real-time verification via the REST API.
How does MillionVerifier compare to ZeroBounce in terms of verification features?
MillionVerifier offers a single email checker, bulk list verification, a REST API, and EverClean for continuous re-verification, similar to ZeroBounce's core verification services. Unlike ZeroBounce, MillionVerifier includes catch-all detection at no extra cost and provides a refund guarantee on emails that cannot be verified with certainty. Both integrate with major marketing platforms, but MillionVerifier's credits never expire, which can be a cost advantage.
What are the main limitations or trade-offs of using MillionVerifier?
MillionVerifier uses a pay-as-you-go model, which requires you to estimate your credit needs in advance, so you might purchase more or fewer credits than you actually use. Additionally, the full tiered pricing table beyond the examples is not published on the homepage, making it less transparent for comparing plans. These trade-offs are offset by the fact that credits never expire and you get a refund guarantee on unverifiable emails.
How is MillionVerifier priced for different usage levels?
MillionVerifier is priced on a pay-as-you-go basis, where you buy verification credits that never expire. It includes a free tier that lets you verify a small number of emails without a credit card, and paid plans provide more usage and features. Catch-all detection is included at no extra cost, and there is a refund guarantee on emails that cannot be verified with certainty.
Can MillionVerifier integrate with my existing email marketing platforms?
Yes, MillionVerifier integrates with 40+ marketing platforms, including Mailchimp, HubSpot, and ActiveCampaign. This allows you to verify lists directly within the tools you already use for campaigns. The integration helps streamline the verification process before you send.
Does MillionVerifier offer a way to continuously re-verify my email list over time?
Yes, MillionVerifier offers EverClean, an automated service that continuously re-verifies contacts connected to an email service provider. This helps maintain list hygiene over time, reducing bounces and protecting your sender reputation on an ongoing basis. EverClean works alongside your existing integrations to keep your list clean.
What kind of refund guarantee does MillionVerifier provide on verification results?
MillionVerifier provides a refund guarantee on emails that cannot be verified with certainty. If the service cannot determine the validity of an email, you are refunded the credit used for that verification. This reduces the risk of paying for uncertain results, making the service more cost-effective.
