Postscript vs Ghost: at a glance
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.
What is Ghost?
Ghost lets publishers store their own member details in custom fields.
Ghost now lets publications define custom fields and store member details directly in Ghost. It follows a run of member email automation releases: tier-specific welcome sequences and automation analytics in October, then lifecycle triggers on 4 November that start flows when a paid member changes tier or leaves.

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.
Ghost
5.0MKT AUTO
Ghost lets publishers store their own member details in custom fields.
◆ Current state
Ghost now lets publications define custom fields and store member details directly in Ghost. It follows a run of member email automation releases: tier-specific welcome sequences and automation analytics in October, then lifecycle triggers on 4 November that start flows when a paid member changes tier or leaves.
◆ Where it's heading
Ghost is building out its member database so automations have more to act on. Custom fields are the data layer the triggers and sequences have been missing, which points toward segmenting and targeting by publisher-defined attributes.
◆ Prediction
Expect automations or email segments to filter on custom fields next; the entry does not say whether fields can be set through signup forms or the API.
