AcyMailing vs OneSignal: 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 OneSignal?
OneSignal's release notes are buried under a competitor-comparison content engine.
Every entry in the current window is marketing content. The newest three are lifecycle-tactics posts — onboarding when a user has done nothing yet, six underused behavioral triggers, and an argument that back-to-school seasonality applies outside retail. Behind them sit competitor-displacement listicles aimed at Firebase and Klaviyo switchers, migration-cost framing, an AI-tools use-case map, and a compliance explainer on French and Italian email-tracking guidance. The actual product record lives in the monthly 'What We Shipped' digest, which this volume has now pushed down to rank thirteen — the July edition cited conversion metrics, deliverability insights and more ways to connect an AI assistant.

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.
OneSignal
5.0MKT AUTO
OneSignal's release notes are buried under a competitor-comparison content engine.
◆ Current state
Every entry in the current window is marketing content. The newest three are lifecycle-tactics posts — onboarding when a user has done nothing yet, six underused behavioral triggers, and an argument that back-to-school seasonality applies outside retail. Behind them sit competitor-displacement listicles aimed at Firebase and Klaviyo switchers, migration-cost framing, an AI-tools use-case map, and a compliance explainer on French and Italian email-tracking guidance. The actual product record lives in the monthly 'What We Shipped' digest, which this volume has now pushed down to rank thirteen — the July edition cited conversion metrics, deliverability insights and more ways to connect an AI assistant.
◆ Where it's heading
Two content tracks are running side by side. The displacement track frames an incumbent messaging stack as a liability and moves the comparison axis from channel count to AI readiness. The newer track is tactical: sends triggered by external signals, pre-churn cooling signals, seasonal windows for non-retail apps — all describing behavior-led orchestration rather than broadcast. That second track reads as demand generation for orchestration features rather than evidence of them shipping. At roughly three posts per publishing day, a monthly digest is outnumbered before it is a week old.
◆ Prediction
The August digest is where any real change will surface, and it will be buried within days on this cadence. Whether the behavior-triggered sends these posts describe are configurable today or aspirational is not readable from the feed.
