Best email / sms in the game. We switched from Klaviyo and its been a game changer. The migration was super easy (they migrated all our email flows / contacts) and shopper + the new CDP they've built helps us with 1:1 communication at scale

I genuinely like Postscript and appreciate what the platform has to offer. However, I'm disappointed with how difficult it is to reach a real person when I need assistance. AI support is helpful for basic questions, but when an issue requires more attention, customers should have an easy way to connect with a human representative. Good customer service is just as important as the platform itself, and I hope Postscript makes this a priority.

App won't approve you and then will charge you for services you never used and never approved and refuse to give you a refund. No real customer service. Total scam. Do not download.

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.
