A side-by-side editorial comparison of AcyMailing and Mailmeteor — release velocity, themes, recent moves, and the top alternatives to consider.
AcyMailing keeps a steady maintenance cadence with a fresh SQL-injection patch
AcyMailing is a Joomla/WordPress email-marketing extension shipping frequent point releases. The recent stream is dominated by security hardening and bug fixes, punctuated by small feature additions to subscription forms, automations, and statistics. It reads as a mature product in maintenance mode: reliability and security over new surface area.
Mailmeteor pushes past simple mail-merge toward AI assistance and serious-sender deliverability.
Mailmeteor is a Gmail-native mail-merge and outbound tool that has spent the last year expanding on two fronts: AI assistance across the mail lifecycle, and deliverability infrastructure for higher-volume senders. Recent releases add a Deliverability Hub for sender-health visibility and Inbox Rotation for spreading campaigns across multiple accounts.

The recent stream is dominated by security hardening and bug fixes, punctuated by small feature additions to subscription forms, automations, and statistics. It reads as a mature product in maintenance mode: reliability and security over new surface area.
The arc is incremental refinement of an established feature set — tightening subscription-form and unsubscribe security, fixing statistics/timezone edge cases, and adding granular options (IP-collection toggle, stats-recording delay). Security patches recur often enough to be a core part of the cadence, suggesting active vulnerability management rather than expansion into new capability.
Expect the pattern to continue: more 10.11.x point releases combining a fix batch with occasional small subscription/automation options. A directional feature jump isn't indicated by these entries.

Recent releases add a Deliverability Hub for sender-health visibility and Inbox Rotation for spreading campaigns across multiple accounts.
Two throughlines are visible. AI has grown from a July 2025 writer (Sheets, Gmail, Dashboard) into a January 2026 reply assistant, moving Mailmeteor from 'send campaigns' toward managing the whole conversation. In parallel, deliverability tooling — warm-up bundled into Pro, then the Deliverability Hub and Inbox Rotation — is repositioning the product for 'serious senders' who need sender health and scale, not just personalization.
Expect deeper deliverability tooling (reputation monitoring, per-sender analytics) building on the Hub, and continued extension of the AI assistant from replies toward more of the send-and-follow-up loop.
