DoubleTick vs mailcow: at a glance
What is DoubleTick?
WhatsApp-commerce blog feed is stale — newest entry is late 2024
DoubleTick's feed is WhatsApp-commerce how-to content — CRM roundups, broadcast guides, and selling tips for SMBs. Notably the entries all date to late 2024, so the crawled feed appears stale and no recent activity or changelog is visible.
What is mailcow?
mailcow's release notes are almost entirely upstream security currency.
mailcow ships named seasonal releases with lettered revisions, and nearly every revision exists to pull in an upstream security fix - Redis, ClamAV, SOGo, Rspamd, nginx, unbound, Postfix. Revision B of the Mooly 2026 release updates Redis 7.4.10, ClamAV 1.4.6, and SOGo 5.12.10, adds minor web UI and nginx hardening, and removes a legacy DeltaChat sieve rule. The last release with genuinely new features was the March cut, which added forced 2FA, ACME DNS-01 challenges, and a passwordless autodiscover endpoint.

DoubleTick
0.0COMMS
WhatsApp-commerce blog feed is stale — newest entry is late 2024
◆ Current state
DoubleTick's feed is WhatsApp-commerce how-to content — CRM roundups, broadcast guides, and selling tips for SMBs. Notably the entries all date to late 2024, so the crawled feed appears stale and no recent activity or changelog is visible.
◆ Where it's heading
The content positions DoubleTick around WhatsApp marketing and sales enablement, but with no 2025 or 2026 entries the trajectory is indeterminate — either the blog stopped updating or the crawler is pointed at an archived feed.
◆ Prediction
Without fresh entries no confident prediction is possible; the feed source most likely needs re-pointing to current content.
mailcow
5.0COMMS
mailcow's release notes are almost entirely upstream security currency.
◆ Current state
mailcow ships named seasonal releases with lettered revisions, and nearly every revision exists to pull in an upstream security fix - Redis, ClamAV, SOGo, Rspamd, nginx, unbound, Postfix. Revision B of the Mooly 2026 release updates Redis 7.4.10, ClamAV 1.4.6, and SOGo 5.12.10, adds minor web UI and nginx hardening, and removes a legacy DeltaChat sieve rule. The last release with genuinely new features was the March cut, which added forced 2FA, ACME DNS-01 challenges, and a passwordless autodiscover endpoint.
◆ Where it's heading
For a self-hosted mail stack that bundles a dozen upstream components, keeping current with their CVEs is the product, and mailcow has organized its release cadence around exactly that. The pattern is consistent: a named release with some feature content every few months, then lettered revisions that are pure security currency plus small web UI escaping and validation fixes. The web interface is where mailcow's own code gets hardened - HTML escaping in quarantine views and sieve editors recurs across several revisions.
◆ Prediction
Expect the next entry to be another lettered revision carrying upstream updates, with the next named release likely bundling whatever feature work has accumulated since March.
