OneSignal's feed is channel-marketing content, with RCS as the recurring drumbeat
A side-by-side editorial comparison of Sender and AcyMailing — release velocity, themes, recent moves, and the top alternatives to consider.
Sender is filling out from a budget email tool into a fuller marketing platform, now reaching into transactional sends.
Sender ships roughly monthly and has spent the past two quarters closing the feature gaps that separate it from pricier marketing platforms. December brought transactional emails — its first move beyond pure marketing sends — alongside a rebuilt dashboard; since then it has refreshed the email builder, added brand settings, and pushed ecommerce reports down to the Standard plan. Several feed entries are tutorials and best-practice posts rather than releases.
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.

The direction is breadth at an accessible price: landing pages, transactional email, ecommerce events and reports, all aimed at small ecommerce senders who'd otherwise stitch together multiple tools. Moving features down to lower plans points to a land-and-expand pricing strategy. Expect more ecommerce-trigger automation and continued parity-building with the Mailchimp/Brevo tier.
The next likely moves are deeper ecommerce automation — event-driven flows building on Custom Events — and further transactional and deliverability features now that that surface exists.

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.
