Sender vs AcyMailing: at a glance
What is Sender?
Sender rebuilt its email builder and grew workflow templates from 9 to 79 after the MCP launch.
Sender's autumn work is on the creation side of the product. The new email builder, in September, uses one flexible container for every layout. October took the automation library from 9 pre-built workflows to 79, with 5 industry collections, 5 new categories and 19 sequence types. Those follow August's MCP server and rebuilt subscriber import; the Capterra ranking post in the same week is marketing, not a release.
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.

2.5MKT AUTO
Sender rebuilt its email builder and grew workflow templates from 9 to 79 after the MCP launch.
◆ Current state
Sender's autumn work is on the creation side of the product. The new email builder, in September, uses one flexible container for every layout. October took the automation library from 9 pre-built workflows to 79, with 5 industry collections, 5 new categories and 19 sequence types. Those follow August's MCP server and rebuilt subscriber import; the Capterra ranking post in the same week is marketing, not a release.
◆ Where it's heading
The MCP server changed how data leaves Sender, and these releases cut the effort of getting campaigns in. Templates and a looser layout model both shorten the path to a first send, which fits Capterra's 'Best for the Tightest Budgets' label. The feed still mixes marketing posts with releases, so cadence overstates shipping volume.
◆ Prediction
More industry collections are the simple extension of the template library. Write actions on the MCP server remain the open question, since the entries still describe read access only.
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.
