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 Customer.io?
Customer.io puts experiments inside automations and makes Design Studio the default editor.
Customer.io is consolidating messaging work into its own canvas. On November 9 Design Studio became the default email editor, covering SMS, WhatsApp and inbox messages too, and Experiments arrived for testing whole multi-step paths inside an automation. The week before brought dynamic SMS senders by country, click heatmaps and per-language rules for auto-translate, after sign-up forms, the Object trigger and new API keys.

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.
Customer.io
5.0MKT AUTO
Customer.io puts experiments inside automations and makes Design Studio the default editor.
◆ Current state
Customer.io is consolidating messaging work into its own canvas. On November 9 Design Studio became the default email editor, covering SMS, WhatsApp and inbox messages too, and Experiments arrived for testing whole multi-step paths inside an automation. The week before brought dynamic SMS senders by country, click heatmaps and per-language rules for auto-translate, after sign-up forms, the Object trigger and new API keys.
◆ Where it's heading
Releases are moving testing, translation and content creation into the places teams already build journeys, so fewer steps need an outside tool. Daily-cadence shipping across messaging, data and AI translation suggests a broad push rather than one flagship bet.
◆ Prediction
Expect Design Studio to add the channels it says are coming and Experiments to gain reporting or winner automation inside the workflow view.
