Postscript SMS Marketing

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 Postscript. I contacted support immediately and provided screenshot evidence showing the credit balance before it disappeared. Their own support representative acknowledged the missing credits and told me the issue was being escalated to billing to investigate and locate them. Instead of correcting the billing issue, we were repeatedly told that because our account was on their legacy billing system, Postscript no longer had the ability to troubleshoot or restore credits and that we should migrate to their newer usage billing system. Migration was not the issue. We were simply asking Postscript to provide the credits we had already paid for or refund their value. Postscript never confirmed that migrating would even restore the missing 14,327 credits. Eventually, support explicitly told us that they were unable to add the missing funds back as credits. They acknowledged that they did not want us to “lose out on what [we’ve] spent,” yet no refund, reimbursement, account adjustment, or other resolution was offered. During this process, multiple support tickets were marked resolved even though the billing dispute was still unresolved. Messages were repeatedly shown as read without substantive responses, and we had to open additional tickets just to try to get someone to address the actual issue. After years as a customer and tens of thousands of dollars spent with Postscript, I find it unacceptable that a billing issue involving paid credits was handled this way. A legacy billing system may no longer be their preferred product, but customers should not lose money they already paid simply because Postscript says it no longer has the tools to correct a problem on that system. We ultimately had to file a dispute with our credit card company, export our subscriber data, cancel our Postscript account, and move to another SMS provider. This entire situation could have been resolved very simply by restoring the 14,327 credits or refunding the $144 we paid for them. Instead, we spent days opening tickets, escalating the issue, and repeatedly explaining the same billing problem without receiving a resolution. After this experience, I cannot recommend Postscript to other retailers or businesses. UPDATE 9/3/2026 while we were waiting to transfer to another service Postscript removed $43 worth of credits! So a total of approx $187 was taken from us via credits. 0/10 DO NOT RECOMMEND!!! Its one thing to have a faulty billing system its on ANOTHER LEVEL to admit that and then refuse to refund or reinstate any credits. WILDDDDDD!

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.

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.

I can't believe the lack of customer service. NO ONE is available on chat and no response from your email team either. What a colossal disappointment!

It never works

They charge $25 even if you havent sent any text marketing out, trying to find another text marketing app to go with

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.

Dont fall for their scam.... This app advertise a plan at 0$ but they charge you 25$ even if you dont use it and refuse to refund it. The use a loophole of advertising free but its not free its 25$ a months even if you dont use it. I downloaded it and wanted to see the features but I didnt use it and they charges me 3 months which they refuse to refund. Such a bad customer service and business model it should be illegal to advertise a 0$ plan if its 25$ minimum that you are being charge anyway

I thought i experienced bad customer service. This is by far the worst. Horrible customer service. Would not recommend it to anyone. The sale tried to get me to sign the contract but they have 0 customer service, especially for the lower plan, I am not sure about the other plan. Also, people seem to be not knowledgeable. I want to get out of the contract.

Postcript is billing me for a service that I have not had or used for several months. Their loophole to refusing to resolve this issue is that the service is installed on my website. If that were true, I would be able to uninstall it, correct? However, I cannot uninstall it because it isn't installed. This is resulting in them continuing to bill me month after month for a service I have no access to. I don't know what else to call this but fraud. I've been emailing their rude customer service agent for days with no resolve, and they are dragging this out to continue billing me.

Be careful. They will lock you into a contract and auto renew it with no notice. We wanted to cancel but unfortunately we were about a week after renewal date. Instead of understanding our situation and charge a prorated fee or any other solution, they were asking a $7,392.42 buyout fee. They don't care, no exceptions, whatever your circumstances might be. We are stuck paying for this app for another half year even though we wanted to switch back to Klaviyo.

Postscript does not integrate with zapier. You dont get any data from phone only subs. Not even their name.

Their terms on rollover credits is not obvious. You have to read their terms of service. My bad for not doing so but I reached out because I spent $200/month for 9 months not knowing and trying to stockpile my credits - so $1800 and they were unwilling to help me recoup any of my wasted money or credits.

Canceled my subscription and was still getting chsrged

0/10 for customer service. they will waste your time.

STAY AWAY OF THIS APP! Their customer support is terrible. We have a problem verifying the TOLL number which said not to approve our account because related to "sells products considered to be prohibited content". We have nothing to do with weed or alcohol, just a beauty supply. We reached out to them twice, not even a solution, sending us a bunch of bsh!t instructions and left.

is not working for my customers! i got no help to translate in Norwegain. Sms code is not working and email for weeks!

I have been a postscript customer for 1.5-2 years and I would highly recommend not using them. I've found other service providers who give 100x better service at a much lower price. I'm perplexed as to how this software has a 4.9. They have been charging us for 6 months even though we expressed that we want to unsubscribe. Post billing us for no usage for 6 months, after uninstalling the app they have billed us almost 2000$ in a month. I am deeply disappointed in how shopify allows such companies to bill us in such a fraudulent ways. Topping all of this off, is their support who will never try to solve the problem and will reroute you to their sales and legal teams who will only try to retain you for longer by baiting your own money. I've not found such a terrible app all my life and I would caution any shopify owner on using postscript.

I am trying to send an SMS campaign, but I could not send it due to a system problem. I tried to contact customer service many times, they said they would get back to me, but they never did.

If I could give this app zero stars I would. My company has been using this app over a year and the experience is the worst. Taking money from small business owners and not delivering is the worst form of business practice. Whenever we text our customers the messages are not being delivered but your company is getting compensated. We reached out to customer service to get a resolution and instead of assisting my company we received the run around. Some of my customers aren't receiving our marketing messages and your company needs to reimburse us.

Tedious to navigate. Customer service lacking, usually takes days and several reps, to answer most simplest concerns.

I changed to their new plan - "charge by usage" - like four days ago, to save some money because I didn't use SMS Marketing as much. I went from paying $50 a month, to being charged $987 in three days out of nowhere. I literally sent out two campaigns and have 511 subscribers. Before this, I used this app occasionally and it went well, but this was outrageous.

I used to LOVE this app, until they change their billing, I currently have only 400 sub on my list, I was paying $25 a month for 2500 credits, which was good for my growing business, I decided to try their free plan little did I know I'll be charged .15 for each text. Which is so unfair!!! I hate that I switch my plan. I'm going to find another provider that cares!! Not fair for growing businesses!!!!

Shiny modern app but it does not sync well with Shopify and it is deceptive. They don't mention that "international" SMS is 10 times (yes TEN times) the cost of US SMS. It's not mentioned on their app listing nor on their pricing page, only hidden away in the documentation. By international it literally means any other country so if your store is strictly restircted to US you're better off with one of the other SMS apps.

Postscript was recommended to me as the leading SMS platform for Shopify, and they have some good features that are hard to find. However, the honest truth is I can't say Postscript is reliable enough to recommend. It's littered with bugs and frequently either fails to send automations or sends them in error, which is a real liability to our communications with our most valuable customers. I've probably spent weeks of my time as a founder working with their support team to resolve bugs and problems with their product. Customer support was initially helpful but frequently fails to follow up and requires reminders from me to solve problems. A recent issue with Postscript caused an order to initiate without a customer's consent, and 7 weeks later we're still waiting on an explanation or resolution. I've worked on software startups for a decade and cannot understand the poor technology execution at Postscript. They are abundantly capitalized, with a large engineering team, and the product cannot be relied upon to do what it promises to do.

Don’t get involved with them. Postscript was amazing. We tried multiple SMS platforms- we finally felt at "home" Peter helped us get setup and he was great. Then we worked one on one with Joe, his patience and knowledge to get the most out of the app was amazing. Then we kept getting passed from person to person and now- now they won’t strategize with us monthly at all. Seems like they have a ton of turn over. Ran and operated very poorly. Not iPhone friendly.

When I first signed up for Postscript, I really liked it. Simple, easy fair pricing. I then took a break to try Attentive as I was offered a really appealing rate. I shut off Postscript, but noticed even with no texts going out, that every month within the first few days, it said all my credits were used.....which was not possible and the "sent texts" reflected this - 5,000 credits gone, with 0-124 texts sent only. Support said this is an "a typical issues" and they couldn't find the reason I was being ripped off. Their solution, was to push me to their new pricing plan which was $500 for all the same features.....a TOTAL SCAM. Disgusting. Their team wasted my time and although nice, were not very professional or accommodating. Attentive offered me upfront a much better pricing structure, I am not sure if I can share publicly so I will not, and we are a small company. Each site the bill is around $50-$150 a month. Honestly I am so disgusted with this company. Their software has an error, ripping me off, and they want ME TO PAY FOR it by switching to their new billing system which is $500/month for the pro plan, to have the same features I currently have. Sadly after somewhere around 3 years, I will be canceling all our Postscript accounts. Disgusting. One of the worst scams I have ever been exposed to. How many people actually keep track and audit texts vs credits? You should! And they wanted to switch me to an uncapped pay as you go model for 10x the price...yah, ok!

I have used Postscript for 1.5 years now. We have had TONS of issues, but support was usually there to help. I should've left the app months ago when campaigns were supposedly sending (and I was paying to have them sent), but no one was receiving them. Postscript brushed it off like it was a one time error and fixed campaigns. Without me noticing that no one on our team received campaign I would have never know it didn't get sent out correctly. However, that is not why I would not recommend. I would not recommend because since we started with them we always had the same short code... A short code is text blank number with blank word to sign up for our texts. We noticed that although people would text the number our list wasn't growing.... turns out another brand with similar name purchased our short code, so they were getting all of our subscribers. Postscript NEVER told us that our short code was no longer offered by them. We emailed them to see why our short code wasn't working and they said they are no longer offering them. We would need to pay $1,000 A MONTH if we want to use our short code that was previous free. They said they sent emails letting people know short codes were going away, but I did not receive a single email. This is a huge deal and not something that should've been emailed or brushed off as not a big deal. They should have had a pop up check box in app, so that everyone had to acknowledge that it was not being offered anymore. I personally think they did not inform their customers because they didn't want a mass amount of customers leaving. Unethical in my opinion. Overall I would not recommend. I would recommend Klayvio or Attentive.

Picked a plan and got a free trial. Spent hours learning how to use it with the videos. Then one day they just shut it off. Said I did it. I didn't even know it until I checked on it. This right before Christmas. Blamed me and said someone on my team must have done it. I am my team. So I know I didn't do it.

The app has bugs and the support is absolutely unprofessional. Asks several times if the private key was used instead of the public key. As if you were an idiot.

Postscript removed themselves from our store without any notice (I had to ask customer service what was going on). Incredibly disrespectful to small business owners and I will not be recommending them due to their poor customer service and treatment of people who are seen as "other" and unimportant to them. They claim to be following the SHAFT guidelines on regulations for sex, hate, alcohol, firearms, or tobacco, but there are actually different guidelines for how to treat companies in different industries depending on whether they are federally legal or not. Also, there is no definition to what terms like "sex" are (is it pornography? a vaginal health device? erotica? something else?) so Postscript can use SHAFT to offer their services based on their own definition of what's considered "sex" and what's considered "health". Here's is the PDF with more information: https://www.wmcglobal.com/hubfs/CTIA%20Short%20Code%20Monitoring%20Handbook%20-%20v1.8.pdf Considering they pride themselves in following regulations to the T I'm disappointed that they're treating companies like this without any notice whatsoever.

I tried to use this app it took us 2 days to try to figure everything out, finally got our first text message out and then we find out that there was an automated welcome message with a discount code we didn't set up or know about. Was completely off brand and not something we wanted I even had told someone in chat help that we didn't want anything automated right now. Will be looking for a different app for our SMS needs
