MailerLite vs Postscript: at a glance
What is MailerLite?
MailerLite is teaching agents to run campaigns, with the sending guardrails baked in.
MailerLite is shipping across three fronts at once. The Simple Editor gained code blocks, video embeds, per-heading font sizes and a full colour picker; any automation step can now be copied and pasted, including incomplete ones; and e-commerce triggers grew variant-level targeting. Running alongside that is a distinct agent track - an installable email marketing skill for Claude, Cursor and around 70 other tools, followed by a listing in the ChatGPT app directory.
What is Postscript?
Postscript is handing SMS marketing to an agent that decides each subscriber's next message
Postscript is an SMS and RCS platform for Shopify merchants, and this archive shows it working two fronts at once. On acquisition it has multiplied the places a subscriber can opt in — embedded forms droppable on any page, standalone landing pages built on the popup editor, and Onsite Opt-in at Shoptin checkout. On messaging it is building Shopper, a conversational AI layer that now answers, analyses and increasingly initiates. The feed carries no publication dates, so this is an archive rather than a timeline.

MailerLite is teaching agents to run campaigns, with the sending guardrails baked in.
◆ Current state
MailerLite is shipping across three fronts at once. The Simple Editor gained code blocks, video embeds, per-heading font sizes and a full colour picker; any automation step can now be copied and pasted, including incomplete ones; and e-commerce triggers grew variant-level targeting. Running alongside that is a distinct agent track - an installable email marketing skill for Claude, Cursor and around 70 other tools, followed by a listing in the ChatGPT app directory.
◆ Where it's heading
Two arcs are moving in parallel. The editor and automation work is convergence: the Simple Editor is being built toward the capability of the Drag and Drop and Nebula builders rather than kept deliberately minimal. The agent track is newer and shaped differently - MailerLite is shipping an opinionated policy about how an agent may send mail, not just an access path to the API.
◆ Prediction
Variant triggers are live on Wix with BigCommerce, Shopify, PrestaShop, WooCommerce and Shoper named as pending, so those are the next obvious landings. On the agent side the entries leave open whether the skill's sending constraints stay advisory or get enforced server-side.

Postscript is handing SMS marketing to an agent that decides each subscriber's next message
◆ Current state
Postscript is an SMS and RCS platform for Shopify merchants, and this archive shows it working two fronts at once. On acquisition it has multiplied the places a subscriber can opt in — embedded forms droppable on any page, standalone landing pages built on the popup editor, and Onsite Opt-in at Shoptin checkout. On messaging it is building Shopper, a conversational AI layer that now answers, analyses and increasingly initiates. The feed carries no publication dates, so this is an archive rather than a timeline.
◆ Where it's heading
The centre of gravity is shifting from campaign tooling to per-subscriber decisioning. Shopper began as a responder, then gained a research surface over its own conversations, and now decides send timing and content for each individual. Alongside that, RCS is the delivery-side bet: webviews, dynamic product photos and tappable suggested replies all work to make the message thread the destination rather than a pointer to the storefront. Experimentation is being pushed into more of the journey rather than confined to campaign sends.
◆ Prediction
Expect the remaining hand-built primitives — static flows and manual segments — to be folded into Shopper's decisioning, and each new RCS capability to keep shipping with an automatic MMS or browser fallback so merchants can adopt it without maintaining a second path.
