Recent reviews rate below this app's own average
Reviews in the last 12 months average 1.50, 3.37 stars below the lifetime average of 4.87. Worth reading the newest reviews before installing.
Computed from the 1,146 reviews we hold, with 12-month windows measured to 2026-08. This scores the public review record — it is not a review of the software itself, and a low score often means we hold little evidence rather than poor evidence.

I used this in 2023 with good results, decided to use it again for an SMS campaign. The app is glitchy, random lines of code are often in the app and changes don't save consistently when I am creating messages or popups. Additionally, I tried to use their template automation for a winback campaign I am now on my 3rd conversation with support because the triggers aren't set up right. Unimpressed with the app, especially for the price.

This app just stole $500 from my account as a service fee which means whether you use the platform or not you are charged $500 upfront plus per minute. They are very expensive and dishonest. Do not do business with them.

they offer a "free plan" but charge you $49 even if you didnt send any text messages. a scam for small business owner, this fee wasnt included in the free plan when i signed up

I LOVED Postscript. And then this year they instituted a new monthly charge in ADDITION to charges per message sent. I enjoyed the $200 credits plan for years. Then they MADE me choose the new pans, even though I had credits through March 2. Not happy. I had to uninstall to receive my refund.

Updating my review from a few years ago as customer service has gone downhill or almost nonexistent. Technical products like this that are prone to glitches need actual customer support. I reached out via email in November and it took days to hear back. Who wants to go back and forth via email over the course of days when it could be solved in minutes? And replacing it with AI support is a leap backward.

I gave it a try and here is my assessment of the app: It has good ideal features, two major issues: 1. Techs support is terrible. If the question cannot be answered from the AI support system, then no human will contact you. I'm still waiting. I give it credit, the AI system is good, but not that good. 2. No dynamic cross syncing between the app and the the SMS Shopify users. Meaning, if a user signs up through Postscript, the Shopify profile is not updated. If a user signs up via Shopify, then you have to manually import. This needs to be dynamic.

Overall I really like using postscript, it is easy to build out flows, make campaigns, and segment your list, their support is helpful and quick. and I like how you can A/B test your popups to see which ones get the best opt-ins,

I thought I liked Postscript, until their customer support team told me I was able to cancel and out of contract before I apparently was. The fun part, they do not include your contract anywhere in their platform billing, so if you have been with them for three years like I have and decide you want to move on - you basically have to dig through files to ensure you are out of contract (which for me was yearly and rolled into another YEAR LONG term). The day before the next billing cycle starts I tried to confirm I am uninstalled and won't be charged in February, but the joke is on me. Turns out their customer support is terrible. Don't use this service.
