OttoKit
OttoKit keeps widening its WordPress trigger surface one plugin at a time
A side-by-side editorial comparison of AcyMailing and Buttondown — release velocity, themes, recent moves, and the top alternatives to consider.
AcyMailing spent 11.0 on a security rewrite and is now paying down the regressions.
Patch releases arriving every few days since the 11.0.0 major. The 11.0.x line is dominated by fixes to what the rewrite disturbed — automation conditions, campaign send settings, custom field handling, add-on integrations — with small improvements alongside, such as REST API errors when a campaign targets disallowed lists and faster module insertion in emails.
Buttondown ships almost daily, and most of it is someone else's bug report closed.
The changelog is a near-daily log of two to four items, overwhelmingly fixes, many crediting the customer who reported them by name. The editor accounts for a disproportionate share — pasted Word documents locking it, cursors that would not sit between stacked tables, blank lines above tables that could not be deleted. Feature work is smaller and steadier: multi-select subscribe form fields, a searchable font specimen panel, Bluesky link cards that re-sync themselves.

The arc is consolidation, not expansion. 11.0.0 reworked the codebase for security and added GDPR-aware pixel tracking; 10.11.1 before it patched a SQL injection. Since then the work has been stabilizing that base, and the attachment fix in 11.0.3 even asks administrators to re-upload files or correct permissions.
Expect continued 11.0.x patches closing regressions from the rewrite before any new feature work resumes.

The pattern is a small team working a public queue in the open, and the fixes cluster where newsletter software actually breaks: rich-text editing, subscriber state transitions, and cross-posting to social platforms. Several recent items concern silent failures specifically — automations skipping sends without saying so, cross-posts marked failed after publishing, resubscribes quietly changing subscriber state. Correcting quiet-wrong behaviour into loud-correct behaviour is the through-line, and it matters more in a product where a mistake reaches someone's whole list.
Expect the cadence to hold and the editor to keep generating items, since that is where the reported bugs concentrate. The entries are day-stamped batches, so individual releases carry no version or theme to read direction from.
