Working with Postscript is truly a privilege. The team support they provide, the ability to reach them anytime and get a response, was crucial for me. Our regular meetings have made us even more successful in SMS marketing. They stay ahead of the curve on SMS marketing developments. We left Postscript for a short time, but when we didn't see what we were promised, we returned. We continue with Pos...

Just started using post script and it has been great so far. The customer service team is amazing. Was having a small issue and they got right on it! Looking forward to purchasing the subscription.

We love Postscript. It's incredibly intuitive, and support is always fast and reliable. Mackenzie is the best and always friendly and understanding to questions I have regarding the platform. We love Postscript! p.s.where can we purchase the BFCM hats?!

great app for sms marketing! gives $1,000 in credits for new accounts, very easy to set up everything, and if not there are many tutorials on youtube, and lastly has great customer service!

I've used about 4 different sms platforms and I always come back to Postscript. Never leaving!

Amazing support, easy to use
— Reckrare
I have been a Postscript customer for years and unfortunately had an extremely disappointing experience that ultimately caused us to leave the platform. We were on Postscript’s legacy credit billing system and purchased SMS credits as we needed them. After a plan downgrade, 14,327 paid and unexpired credits disappeared from our account, representing approximately $144 that we had already paid Post...

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.
— Upland Original
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 wi...

says free to install, i installed it, barely used it, charged my $67.99 without warning. dont use post script they are scammers
— Gifted XI Clothing
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.
— Kiyamel
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
— JADE
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...
— Doses of Grace
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 si...
