The short answer

Omnisend is the direct replacement for a store. It does the same ecommerce flows at a gentler price curve.

Why people leave Klaviyo

  • Pricing scales steeply with list size, which hurts stores whose list grows faster than revenue
  • Billing and cancellation are the recurring complaint on consumer review sites, even as G2 reviewers rate the product itself highly
  • Deep ecommerce features are wasted on anyone not running a store
  • Migration off it gets harder the longer the flows run

Worth saying plainly: Klaviyo rates 4.6 on G2, where reviewers are verified business users. The software is not broken and it works well for plenty of senders. What the lower Trustpilot figure captures is the commercial experience around it — billing, renewals, getting a human on the line. If neither of those is biting you, switching costs more than it returns.

What moving actually costs you

Contacts, tags and segments export as CSV and import cleanly almost everywhere. That part takes an afternoon. Automations do not transfer — every flow gets rebuilt by hand in the new platform, and that is where migrations stall. Count your live automations before you commit: under five and this is a weekend, over twenty and it needs a plan.

Two things people forget. Your sending domain needs new SPF and DKIM records, and inbox placement usually dips for a week or two while the new provider's IPs build reputation with your list. Warm up by sending to your most engaged segment first rather than blasting the whole list on day one.

Which of the three fits you

Omnisend — 8.8. Best for shopify and woocommerce stores. Watch out for: little reason to pick it if you do not sell products. Full review.

Brevo — 8.5. Best for large lists that are emailed occasionally. Watch out for: template editor lags the rest of this group. Full review.

MailerLite — 8.7. Best for creators, newsletters and small businesses starting out. Watch out for: automation runs out of room once flows get complex. Full review.

Try before you commit

All three run free tiers. Import a few hundred contacts into Omnisend, rebuild your single most important automation, and send one campaign. If it feels better than what you have now, the rest of the migration is just repetition.
