AcyMailing vs OpnForm: at a glance
What is AcyMailing?
A Joomla and WordPress mailer working off the debt from its security rewrite.
AcyMailing is a newsletter extension for Joomla and WordPress. Version 11.0.0 in late July reworked the code base for security and added a GDPR-aligned option for pixel tracking; the four point releases since have been almost entirely fixes to what that rework disturbed — automation conditions, multilingual campaigns, attachments, the REST API, and a long tail of add-on integrations.
What is OpnForm?
OpnForm makes itself addressable by AI agents, with the permission model built in rather than bolted on
OpnForm is a form builder that spent the last three months stabilising the V2 platform it shipped in June, then began extending it. v2.4.0 is the largest step since V2: an MCP server and a portable Agent Plugin package let AI assistants create and preview private form drafts, hand them to the editor, and — after OAuth — manage forms, read and search submissions, pull form-level statistics and trigger async CSV exports. The same release adds native campaign attribution, capturing UTM parameters and ad click identifiers from standalone forms, embeds, SDK integrations and popups, then exposing them through submissions, webhooks, SDK events and CSV exports.

AcyMailing
5.0MKT AUTO
A Joomla and WordPress mailer working off the debt from its security rewrite.
◆ Current state
AcyMailing is a newsletter extension for Joomla and WordPress. Version 11.0.0 in late July reworked the code base for security and added a GDPR-aligned option for pixel tracking; the four point releases since have been almost entirely fixes to what that rework disturbed — automation conditions, multilingual campaigns, attachments, the REST API, and a long tail of add-on integrations.
◆ Where it's heading
This is the settling phase after a major version, and the cadence shows it: five releases in three weeks, each smaller than the last. Compliance and security are the recurring theme across the whole window, from the patched SQL injection in 10.11.1 to optional IP collection and the tracking-consent preview. Feature work has largely paused while the add-on surface catches up.
◆ Prediction
Expect the point-release cadence to keep shortening as regressions run out, with the next substantive change most likely in the automation or REST API surface that has drawn repeated fixes.

6.3MKT AUTO
OpnForm makes itself addressable by AI agents, with the permission model built in rather than bolted on
◆ Current state
OpnForm is a form builder that spent the last three months stabilising the V2 platform it shipped in June, then began extending it. v2.4.0 is the largest step since V2: an MCP server and a portable Agent Plugin package let AI assistants create and preview private form drafts, hand them to the editor, and — after OAuth — manage forms, read and search submissions, pull form-level statistics and trigger async CSV exports. The same release adds native campaign attribution, capturing UTM parameters and ad click identifiers from standalone forms, embeds, SDK integrations and popups, then exposing them through submissions, webhooks, SDK events and CSV exports.
◆ Where it's heading
The arc runs from platform (V2) through repair (2.1 and 2.2) through automation (2.3) to agent access (2.4), and each layer reuses the one under it. What distinguishes the MCP work is how much of it is authorization design rather than tool surface: delegated OAuth with PKCE, workspace scoping, revision conflict detection, private capability tokens, confirmation gates before publishing or trashing, and a hard rule that submission records cannot be deleted or restored through MCP at all. Self-hosted MCP ships disabled by default and requires Passport plus public HTTPS before it can be turned on.
◆ Prediction
The notes flag public ChatGPT directory registration as a separate, unfinished distribution step, so the next move is likely getting the Agent Plugin listed rather than adding more tools. Expect the usual self-hosted follow-up patches against the MCP guest-draft migrations this release introduces.
