What merchants say

Klaviyo

Recent merchant sentiment is strongly positive, but much of the sample consists of ratings with minimal written explanation. Written comments most often highlight email marketing performance, Shopify integration, ease of use, and early revenue impact, while the clearest caveat is pricing for businesses in a growth phase.

  • ＋ Email marketing effectiveness — Several merchants say the app works well for email marketing and helps support sales or revenue-generating campaigns.
  • ＋ Shopify integration — Merchants note that the app connects smoothly with Shopify and keeps store data in sync effectively.
  • ＋ Ease of use — Some newer users describe the interface as approachable and intuitive despite being early in setup.
  • － Pricing pressure — One merchant says costs rise sharply for growing businesses and recommends carefully modeling pricing before committing.
  • － Segmentation learning curve — One review notes that segmentation requires some learning before it becomes effective.

Watch out: Merchants should review pricing carefully as their contact list or business scale grows.

Omnisend

Recent sentiment is mostly positive, with many 5-star ratings and repeated praise for support, usability, and ecommerce email/SMS features. The main negative pattern is not about core marketing capability, but about support responsiveness, onboarding friction, and communication during technical or compliance issues.

  • ＋ Helpful support — Several merchants credit support staff with resolving setup, payment, SMS, or feature questions effectively.
  • ＋ Ease of use — Merchants describe the app as straightforward to use, especially compared with other email platforms.
  • ＋ Email and SMS functionality — Positive reviews say the email tools, SMS setup support, and campaign capabilities meet ecommerce marketing needs.
  • ＋ Migration and setup help — Some merchants report smooth onboarding or successful guidance when moving from other tools or configuring campaigns.
  • － Slow or inadequate support — Negative reviews most often describe delayed responses, unclear guidance, or insufficient help during technical or migration issues.
  • － Account and verification friction — Some merchants report blocked accounts, prolonged number verification, or compliance checks that felt poorly explained.
  • － Migration issues — One merchant had a failed or delayed migration experience from another SMS platform and felt communication was lacking.

Watch out: Merchants with urgent setup, DNS, migration, compliance, or SMS verification needs should watch for possible delays or unclear support handoffs.
