Customer.io puts experiments inside automations and makes Design Studio the default editor.
A side-by-side editorial comparison of Ghost and OpnForm — release velocity, themes, recent moves, and the top alternatives to consider.
Ghost automations can now start when a paid member changes tier or leaves.
Member email automation has been Ghost's main line since June. October added automation analytics and tier-specific welcome sequences, and on 4 November automations gained lifecycle triggers: a flow can start when a paid member changes tiers or when their subscription ends. Stripe Checkout customization keeps a publication's brand on the payment page.
OpnForm's fourth patch in a week fixes forms and quietly widens self-hosted telemetry.
OpnForm is an open-source form builder with an MCP server for AI assistants. After v2.8.0 cut public-page script requests from 210 to 57 in one test, four patch releases followed: upload limits, integration edits that reported success without saving, guest AI generation and URL filtering, and now v2.8.4's fixes for date-range mention crashes and base64 email bodies. That last release also starts sending the configured hostname in self-hosted telemetry.

Automation is moving past onboarding into the rest of the subscriber lifecycle. With upgrade, downgrade and cancellation triggers, publishers can run retention and win-back flows inside Ghost rather than in a separate email tool.
Further triggers such as free-to-paid conversion or engagement events are the likely next step, following the pattern of one automation addition per month.

That last release also starts sending the configured hostname in self-hosted telemetry.
The October feature run (custom URLs, self-hosted branding, faster public pages) has given way to a stabilization stretch of weekly patches, each fixing regressions or tightening security. The telemetry change suggests the team wants a clearer view of which self-hosted instances are running which release.
Expect patch releases to taper and a v2.9 feature release to follow; the entries do not show whether it extends the MCP layer or the Pro tier.
