Postscript said:

“Expertise and resources focus solely on SMS (and always will!)”

Postscript now:

“It’s here: Postscript Email.”

Postscript changed its roadmap. TxtCart did not.

THE TXTCART PROMISE

“We will never build email.”

Email already has great platforms. TxtCart exists to make SMS and conversational messaging more valuable for ecommerce. Our roadmap, engineering, automation, analytics, and AI remain focused on messaging rather than email. TxtCart will not become an ESP. Product investment stays with SMS and conversational messaging.

Why ecommerce brands switch from Postscript to TxtCart

Postscript now offers one platform across retention channels. TxtCart is for teams that want more control and revenue from text without moving email into the same product.

Choose the best platform for each channel.

Keep the email platform that already works for your team while giving SMS its own automation, conversations, and performance model.

Move SMS without forcing an email-platform migration.

Build more precise text journeys.

Use 22+ triggers, branching, listeners, A/B testing, wait steps, filters, frequency controls, and cancellation criteria to decide when a shopper enters, continues, or exits a Flow.

More control over the journey, without adding another channel to the platform.

Make conversational AI easier to adopt.

TxtCart includes AI Agent access across its plans and charges per resolved conversation. Teams can put conversational AI to work without committing to a separate AI subscription.

Use it for questions, recommendations, recovery, and support.

Postscript is going wider. TxtCart is going deeper.

Postscript’s roadmap now spans email, SMS, and RCS through ACP, a shared customer data and AI layer. TxtCart is making a different product bet: deepen SMS and conversational messaging without becoming an ESP.
