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.
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.
