CartStack vs AcyMailing: at a glance
What is CartStack?
Five months after its rebuild, CartStack's first follow-up is product-level export data.
CartStack recovers abandoned carts and bookings through email sequences, and rebuilt its platform as CartStack 5.0 in June 2026 with a clearer dashboard, a reorganized campaign builder and date-range comparison in reports. The first feature since then adds cart items and attributes to recovered-order, send-queue and send-archive exports, so merchants can see what was recovered, not just that it was.
What is AcyMailing?
AcyMailing 11.1.2 closes holes that let strangers read or unsubscribe any subscriber.
AcyMailing is a Joomla and WordPress email marketing extension. Release 11.1.2 is a security update: it fixes an unauthenticated leak of subscriber data including the subscriber key, anonymous unsubscribing of any known address, logged-in users changing other people's subscriptions, unchecked post-subscription redirects and campaign archive pages opening without permission. It follows 11.1's privacy work, a per-subscriber tracking switch and fixed one-click unsubscribe.

CartStack
2.5MKT AUTO
Five months after its rebuild, CartStack's first follow-up is product-level export data.
◆ Current state
CartStack recovers abandoned carts and bookings through email sequences, and rebuilt its platform as CartStack 5.0 in June 2026 with a clearer dashboard, a reorganized campaign builder and date-range comparison in reports. The first feature since then adds cart items and attributes to recovered-order, send-queue and send-archive exports, so merchants can see what was recovered, not just that it was.
◆ Where it's heading
Release notes come a few times a year and center on reporting and deliverability: aggregate reports, totals, pre-send email validation, one-click unsubscribe, and now product-level exports. The 5.0 post promised a steady stream of features after the rebuild, but only one has shipped in five months.
◆ Prediction
The next releases will likely build on the product data now flowing into exports, for example per-product recovery reporting in the dashboard; the gap since 5.0 makes the timing unclear.
AcyMailing
2.5MKT AUTO
AcyMailing 11.1.2 closes holes that let strangers read or unsubscribe any subscriber.
◆ Current state
AcyMailing is a Joomla and WordPress email marketing extension. Release 11.1.2 is a security update: it fixes an unauthenticated leak of subscriber data including the subscriber key, anonymous unsubscribing of any known address, logged-in users changing other people's subscriptions, unchecked post-subscription redirects and campaign archive pages opening without permission. It follows 11.1's privacy work, a per-subscriber tracking switch and fixed one-click unsubscribe.
◆ Where it's heading
Since the 11.0 security rework in July, AcyMailing's releases alternate between privacy features and fixes for flaws in how subscriber actions are authorized. 11.1.2 shows the 11.0 rework left gaps in the subscription paths, now patched with ownership checks and security tokens.
◆ Prediction
A security advisory with full details is promised once users have had time to update, and further 11.1.x patches are likely as those details invite scrutiny of related code paths.
