Why people consider alternatives to Klaviyo
Klaviyo is an email and SMS marketing platform built for e-commerce. Deep integrations with Shopify, BigCommerce, and stores. Automated flows trigger on customer behavior. Advanced segmentation targets the right customers.
Here are the real cost and limitation gotchas that push teams to look elsewhere:
- Since Feb 2025, you pay for ALL active profiles, not just contacts you email. Imported but unengaged contacts still count toward billing
- SMS credits are separate and do not roll over month-to-month, unused credits are lost
- International SMS costs 5-12 credits per message vs 1 credit for US, dramatically increasing costs for global audiences
- Spending over $10,000/mo forces you into Klaviyo One enterprise tier with a mandatory 20% premium
The 17 alternatives below cover the same core job (email marketing) with different trade-offs.
