What is beehiiv?
Ungated its MCP server while quietly becoming a website platform that also sends email
beehiiv publishes a monthly digest alongside individual feature entries, and the two tell different stories. The dated digests through April 2026 cover Webinars, Automations v4, On-Demand Ads and the first beehiiv MCP. A separate set of changelog entries - carrying no publish date, so they sit outside the dated timeline - adds beehiiv MCP v2, an AI writing assistant in the editor, a rebuilt analytics dashboard with custom ranges and export, an SEO toolkit, a card-level site design editor and referral program upgrades.
What is Customer.io?
Customer.io adds hosted and embedded sign-up forms, so contacts can enter without custom code
Customer.io now captures contacts itself: sign-up forms can run in-app, embed on any page via a script tag, or live on a Customer.io-hosted page, and submissions create or update people in the workspace. That lands days after the public/private API key split and a new Object trigger, on top of an October of snapshot segments, geofence dwell time and Design Studio API coverage.

◆ Current state
beehiiv publishes a monthly digest alongside individual feature entries, and the two tell different stories. The dated digests through April 2026 cover Webinars, Automations v4, On-Demand Ads and the first beehiiv MCP. A separate set of changelog entries - carrying no publish date, so they sit outside the dated timeline - adds beehiiv MCP v2, an AI writing assistant in the editor, a rebuilt analytics dashboard with custom ranges and export, an SEO toolkit, a card-level site design editor and referral program upgrades.
◆ Where it's heading
Two lines are running at once. The first is agent access: MCP shipped in March as a premium-sounding analyst-in-a-box, and v2 removed both the waitlist and the paid-plan requirement, which is a distribution decision rather than a feature one. The second is the steady conversion of beehiiv from a newsletter sender into a web publishing platform - the SEO toolkit, the card editor, and native website analytics only make sense if the newsletter's website is the product surface that matters. Monetisation keeps widening in parallel through Webinars, On-Demand Ads and podcast hosting.
◆ Prediction
The most likely next move is deeper agent capability on top of the now-ungated MCP - write actions and workflow automation rather than the reporting and analysis framing v1 used. Note that the individual feature entries carry no dates in the feed, so the ordering of the recent releases relative to the April digest cannot be established from these entries.
Customer.io
5.0MKT AUTO
Customer.io adds hosted and embedded sign-up forms, so contacts can enter without custom code
◆ Current state
Customer.io now captures contacts itself: sign-up forms can run in-app, embed on any page via a script tag, or live on a Customer.io-hosted page, and submissions create or update people in the workspace. That lands days after the public/private API key split and a new Object trigger, on top of an October of snapshot segments, geofence dwell time and Design Studio API coverage.
◆ Where it's heading
The recent run pushes Customer.io upstream of messaging: it is taking on the steps teams used to wire themselves, from credential setup to audience capture to email content via API. Consent records, polygon geofences and dwell time show the same pattern on the data side, with more state recorded and acted on inside the platform.
◆ Prediction
Expect form-level follow-ups such as form-submission triggers or form analytics, since the rollout runs through 6 November and the entry frames forms as a journey entry point.
