The Human-Powered Postscript Alternative That Customers Love

Thanks for joining our newsletter.
Oops! Something went wrong.

We often get asked how Cartloop compares versus other platforms for conversational SMS marketing. In particular, one competing platform is Postscript. Both platforms are great but differ in a couple of ways, in what they are meant to do, where they are strong, where they are weak, how to try them out, cost, and features.

So to help answer your questions, in this comparison, we take a look at each platform to help you decide which one is best suited for your brand’s specific marketing needs based on features, free trials, availability, pricing and more.

Here’s the bottom line, in our view:

  • Cartloop is the better option for brands that want to engage with shoppers in real-time, right when they need it the most by using the human approach.
  • Postscript is great for brands and stores that want to automate their SMS/MMS marketing and put it on autopilot. 

However, if you’re using Postscript and want to offer both support and marketing to your customers, you’re going to have to rely on a separate app to do that. Or there are platforms like Cartloop that offer full customer lifecycle support that serve for various SMS marketing use cases.

Postscript isn’t focused on conversational SMS marketing 

Unless you just want to blast your subscribers with 1-way SMS/MMS texts, you won’t be able to have a fully-managed conversational SMS approach with Postscript. They are focused on automations and 1-way campaigns that generate revenue but don’t create a solid relationship between you and your customers. 

With Cartloop, however, everything is based on an end-to-end communication happening in real-time. This means, your shoppers are able to reply to any kind of texts and start a 1:1 real-time conversation that can lead to higher ROI and increased LTV.

Postscript doesn’t have pre and post-purchase support

If your customers have shipping or product-related questions after they complete their orders, Postscript won’t be able to assist them. The only way to handle those support tickets is if you’re using a third-party app such as live chat, email or Facebook messenger. 

With Cartloop, we offer pre and post-purchase assistance on technical issues, shipping or delivery information, product-related questions, up-sells/cross-sells, personalized recommendations and much more. These are handled in real-time by Cartloop’s Live Experts.

Postscript doesn’t have 24/7 Live Agents

Unless you don’t mind using your own support team or hire additional members to cover SMS interactions, you’ll have a hard time managing all the 2-way conversations with Postscript as they don’t provide a fully-managed service nor live agents to help.

Postscript doesn’t have personalized product recommendations

If you want to offer your customers a premium experience while shopping, Postscript won’t be able to help. You can either use a third-party app that provides product recommendations or switch to Cartloop which combines AI + humans to personalize your customers’ shopping experience from browsing your store to choosing the right products for them. The Live Experts make relevant product recommendations to your customers, exactly as if they were in a physical store asking for assistance. 

Why Cartloop is the best Postscript alternative

Postscript’s approach listed above explains why it isn’t a viable option as a conversational SMS marketing platform. That’s where Cartloop comes in. Cartloop is the conversational SMS marketing tool designed for fast-growing eCommerce brands. Small to medium eCommerce businesses, and growing brands use Cartloop to manage their 1:1 customer interactions via SMS. With Cartloop, you can easily focus on your business while we text with your shoppers and help them with support, questions or discounts. 

Cartloop vs Postscript Pricing

The all important question: How much do these tools cost? We explain each platform’s pricing model and share the plans they offer.

Cartloop Pricing

At Cartloop, our pricing model is pretty simple.

  • Growth: $49 per month + 7% of Cartloop generated sales
  • Pro: $299 per month + 3.5% of Cartloop generated sales
  • Custom

We also offer a 14-day unlimited free trial that’s available on all plans.

Postscript Pricing

Postscript’s pricing is quite different as it’s based on the number of messages you want to send per month. The minimum starts at 2.500 messages sent per month with $0.0100 cost per message. 

Postscript has a 30-day free trial.
