Postscript vs SalesBlink: 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 SalesBlink?
SalesBlink is making agents first-class clients, and just broke API-key MCP connections to do it
SalesBlink is cold-email outreach software shipping monthly roundups plus one-off announcements. The recent run is dominated by machine access: an MCP server, a CLI, an integration letting Hermes agents run outreach, and now OAuth on the MCP server with 40-plus upgraded tools spanning sequences, leads, inbox, senders and analytics. The rest is polish — Slack alerts over OAuth, branded meeting invites, attachments in replies, faster reply detection.

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.

SalesBlink is making agents first-class clients, and just broke API-key MCP connections to do it
◆ Current state
SalesBlink is cold-email outreach software shipping monthly roundups plus one-off announcements. The recent run is dominated by machine access: an MCP server, a CLI, an integration letting Hermes agents run outreach, and now OAuth on the MCP server with 40-plus upgraded tools spanning sequences, leads, inbox, senders and analytics. The rest is polish — Slack alerts over OAuth, branded meeting invites, attachments in replies, faster reply detection.
◆ Where it's heading
The product is being rebuilt so an agent can operate it end to end rather than trigger it. OAuth removes the API-key copy-paste that made MCP setup a chore, a single endpoint replaces per-client configuration, and the tool count suggests most of the app's surface is now callable. Notably the change is breaking: existing API-key MCP connections have stopped working and must be reconnected, which is a cost SalesBlink was willing to impose to get agent access onto a proper auth flow.
◆ Prediction
With OAuth and 40-plus tools in place, the next constraint is what an agent is allowed to do rather than what it can reach, so expect scoped permissions or approval steps on the sending actions before the outreach ones get widely used unattended.
