Editorial Verdict

AI-researched, not hands-on tested

Omnisend's Shopify integration is genuinely smooth, with real cost savings cited at up to 35% cheaper than Klaviyo for comparable use. The honest catch: the free plan caps at 250 contacts and 500 emails/month (quickly outgrown), and you can't search contacts by phone number -- a segment has to be created instead.
