AcyMailing vs Postiz: at a glance
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.
What is Postiz?
Postiz encrypts channel tokens and lets agents send connect links for new channels.
Postiz's November 13 release encrypts channels' access and refresh tokens in the database when enabled, with a local key or AWS KMS, and needs no migration. A new connect link endpoint and MCP tool let an app or agent give someone a one-hour link that adds their social channel to a workspace. It also fixes two access-control holes (billing routes open to plain members, and post saves across organizations), adds Amazon SES for email, and fixes 40+ provider and billing issues.

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.
Postiz
2.5MKT AUTO
Postiz encrypts channel tokens and lets agents send connect links for new channels.
◆ Current state
Postiz's November 13 release encrypts channels' access and refresh tokens in the database when enabled, with a local key or AWS KMS, and needs no migration. A new connect link endpoint and MCP tool let an app or agent give someone a one-hour link that adds their social channel to a workspace. It also fixes two access-control holes (billing routes open to plain members, and post saves across organizations), adds Amazon SES for email, and fixes 40+ provider and billing issues.
◆ Where it's heading
Postiz still ships large releases about every six weeks. The last three have moved it from a scheduler toward publishing infrastructure that other software and agents can drive, with MCP access, preview comments and now connect links. This release adds the security work, encrypted tokens and tenant isolation, that larger self-hosted and multi-organization deployments need.
◆ Prediction
The next release will likely extend connect links to platforms that need API keys or instance URLs, and keep tokens out of Temporal history, which this release describes as groundwork.
