What merchants say

Omnisend

Recent sentiment is mostly positive, with many 5-star ratings and repeated praise for support, usability, and ecommerce email/SMS features.

  • ＋ 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.

  • － 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.

Postscript

Sentiment in the scraped recent reviews is mixed: positive reviewers value Postscript for usable SMS marketing tools, list-building features, and strong support when it works well. However, the newest negative reviews cluster heavily around billing, pricing changes, cancellation terms, and deteriorating support responsiveness.

  • ＋ Responsive support — Positive reviewers often describe support as fast, helpful, friendly, and confidence-building during setup or troubleshooting.
  • ＋ Ease of use — Merchants praise the platform as intuitive for building flows, campaigns, segments, templates, and popups.
  • ＋ SMS growth and engagement — Some reviews credit the app with growing subscriber lists, improving customer engagement, and supporting sales activity.
  • ＋ Strong overall app quality — A few merchants describe the app as useful, sophisticated, or better than other SMS platforms they have tried.
  • － Unexpected fees — Many recent negative reviews focus on charges despite little or no usage, paid minimums, new monthly fees, or disputed service charges.
  • － Poor support experiences — Several merchants say support has become slow, unavailable, unhelpful, rude, or too dependent on automated responses.
  • － Contracts and cancellation — Multiple reviewers complain about contract lock-ins, renewal terms, cancellation confusion, buyout fees, or difficulty confirming account closure.

Watch out: The most common caveat is recurring frustration over unexpected charges, minimum fees, contract renewals, and cancellation or refund disputes.
