RudderStack vs AcyMailing: at a glance
What is RudderStack?
Open lakehouse streaming and modern native SDKs reshape what RudderStack delivers.
RudderStack is shipping at high cadence across three vectors: open data infrastructure (Snowflake Iceberg streaming destination, P95 latency alerts at GA), modern native SDKs (new Kotlin Android SDK and Swift iOS SDK replacing legacy versions), and integration breadth (Custom Web Device Mode, Singular v2/SDID auto-routing, Braze multi-app keys). Bot Management, Tracking Assistant, and Snowflake Streaming GA from prior weeks set the stage.
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.

RudderStack
3.8MKT AUTO
Open lakehouse streaming and modern native SDKs reshape what RudderStack delivers.
◆ Current state
RudderStack is shipping at high cadence across three vectors: open data infrastructure (Snowflake Iceberg streaming destination, P95 latency alerts at GA), modern native SDKs (new Kotlin Android SDK and Swift iOS SDK replacing legacy versions), and integration breadth (Custom Web Device Mode, Singular v2/SDID auto-routing, Braze multi-app keys). Bot Management, Tracking Assistant, and Snowflake Streaming GA from prior weeks set the stage.
◆ Where it's heading
Two parallel arcs are visible. The data plane is moving toward open lakehouse formats — Iceberg-on-customer-cloud-storage decouples customers from a single warehouse vendor. The collection plane is being modernized end-to-end, with native Kotlin and Swift SDKs replacing older mobile stacks and a new self-serve integration model letting customers ship their own destinations. Together these moves reposition RudderStack as composable infrastructure rather than a closed CDP.
◆ Prediction
Expect Iceberg streaming to extend beyond Snowflake — Databricks Unity Catalog or direct S3-Glue Iceberg as a destination — and the modernized SDK pattern to ship a JavaScript or React Native rewrite next. The Custom Device Mode escape hatch will be productized further as a marketplace for community-built integrations.
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.
