Omnisend review and real cost

Email, SMS and web push marketing with popups, signup forms and prebuilt automations.

Good, with caveats6/8 checks passed#2 of 4 in email and smsBy Omnisend4.7 from 3,186 App Store reviews

Verdict

A good fit for stores that want strong email automation with 24/7 support on every plan, including free. The catch is that SMS now needs the Pro plan, which lifts a 20,000-contact store from $265 to about $515 a month.

Install it if

  • Small stores starting on a free plan that still want live support
  • Stores switching email tools that want the migration done for them
  • Email-first stores that may add SMS later

Skip it if

  • Stores that want SMS on a low-cost email plan
  • Brands that need a named SOC 2 or ISO 27001 certification
  • Stores planning to blast a large, cold list right after switching

Good

  • Free plan for 250 contacts and 500 emails a month, with 24/7 live support2.
  • Every contact tier and US SMS rate is published2,3.
  • Free migration of lists, segments and flows from your old tool2.
  • Works with Shopify Flow, Recharge, Gorgias and Yotpo1.

Not so good

  • SMS needs the Pro plan for anyone subscribing since May 4, 20263.
  • Standard caps email at 12 times your list size each month2.
  • Its data processing agreement names no SOC 2 report or ISO 27001 certificate5.
  • No Built for Shopify badge on the listing1.
