AcyMailing vs Formidable Forms: at a glance
What is AcyMailing?
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.
What is Formidable Forms?
Formidable widens MCP compatibility and locks down signature files
Forms API v2.0.1 makes the Formidable MCP server tolerate the older MCP adapter versions bundled in other plugins such as WooCommerce and Rank Math, instead of refusing with an incompatibility message. Digital Signature Forms v3.2 adds form-level protection for signature files, a role requirement to access them, and permanent deletion of old signatures when an entry is deleted.

AcyMailing
5.0MKT AUTO
AcyMailing spent 11.0 on a security rewrite and is now paying down the regressions.
◆ Current state
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.
◆ Where it's heading
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.
◆ Prediction
Expect continued 11.0.x patches closing regressions from the rewrite before any new feature work resumes.
Formidable Forms
6.3MKT AUTO
Formidable widens MCP compatibility and locks down signature files
◆ Current state
Forms API v2.0.1 makes the Formidable MCP server tolerate the older MCP adapter versions bundled in other plugins such as WooCommerce and Rank Math, instead of refusing with an incompatibility message. Digital Signature Forms v3.2 adds form-level protection for signature files, a role requirement to access them, and permanent deletion of old signatures when an entry is deleted.
◆ Where it's heading
Two threads are running in parallel across the add-on family. One is agent access, opened by the Forms API v2.0 MCP adapter and the WordPress Abilities API, now being made to coexist with the other plugins already shipping MCP adapters on the same site. The other is a sustained security pass, visible in signature file handling, tokenized CSV downloads, and the Stripe and core-plugin hardening earlier in the window.
◆ Prediction
Adapter-version collisions between plugins are likely to recur as more WordPress plugins ship MCP servers, so expect further compatibility patches rather than new API surface in the near term.
