What do merchants say about them?

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.
