Why stores look for a Postscript alternative

Two tools for two channels. Postscript is SMS and MMS first, and its email is rolling out by waitlist (Postscript email), so most stores pay for an email tool beside it.
Three lines on the bill. A monthly platform fee, per-message rates, and carrier fees passed through at cost (Postscript pricing).
Texts and emails that don’t know about each other. With two tools, a shopper can get a text and an email about the same cart.

How to choose

If you want one tool for email and texts, pick one that does both well rather than pairing two.
If you want a predictable texting bill, compare pay-as-you-go per segment with monthly commitments and platform fees at your real volume.
If you need MMS, RCS or two-way conversations, check each tool: Attentive and Postscript offer more channels, and Shopify Messaging’s number can’t receive replies.

Moving your texting subscribers

Marketing texts need prior opt-in, so your consent records have to come with your subscribers. Amy reads the SMS marketing consent Shopify recorded for each customer, and only texts people who opted in. Before you switch, check that everyone who replied STOP in Postscript shows as unsubscribed in Shopify too. Your new number also needs carrier verification before it sends, so start that early and keep Postscript running until it’s done.
