Help Scout keeps adding channels — now a portal customers sign into
Two customer-facing surfaces landed in a week: two-way SMS through a customer's own Twilio number, and a Customer Portal where a company's contacts sign in to see support history raised across their organization. Underneath, the SLA system built out in May and June now drives workflows, views, and reporting. Per-inbox office hours, away auto-reassignment, and availability status on web and mobile fill in the operational layer.
Postmark ships Skills for AI coding agents and an async-first Python SDK — leaning into the agent-built-app era.
Postmark released two coordinated developer-platform moves. First, an open-source set of 'Postmark Skills' designed to teach AI coding agents — Claude Code, Cursor, GitHub Copilot, OpenAI Codex, Gemini CLI — accurate Postmark API context, covering send/batch/bulk, inbound, templates, webhooks, and message streams. Second, an official Python SDK built async-first, with split ServerClient and AccountClient surfaces and Python 3.10+ support. Around these, the team is highlighting bulk email send capabilities and routine maintenance (Axios 1.13.5 in the JS SDK).

The product is widening from an agent-side inbox into the places customers actually wait — SMS, WhatsApp, and now a signed-in portal with company-level visibility. Portal access sitting on Plus and Pro puts the newest surfaces on the paid tiers rather than across the board.
Expect the portal to pick up what adjacent surfaces already have — SLA status, more self-serve actions — and the channel list to keep widening rather than any one channel getting deeper.

Postmark is positioning for a market where AI agents are the integrators, not just human developers. The Skills release is a direct response to the failure mode the team itself names — agents writing 'code that looks right but isn't' against transactional-email APIs. By shipping curated context as an open standard, Postmark stakes out the ground that whoever feeds correct knowledge into agent toolchains earns the integration calls. The async-first Python SDK fits the same thesis: agents and modern Python apps both want non-blocking calls by default.
Expect Postmark Skills to expand to inbound parsing and event-driven flows, and the open-standard framing to invite peer ESPs (Resend, Loops, Customer.io transactional) to publish their own Skills — at which point the question becomes whose Skills agents actually reach for. Watch for an MCP server next; it's the natural pairing with Skills for runtime tool calls.
