Element vs mailcow
A side-by-side editorial comparison of Element and mailcow — release velocity, themes, recent moves, and the top alternatives to consider.
Element vs mailcow: at a glance
What is Element?
Element Web is opening an extension surface while rebuilding its timeline underneath.
Element Web ships on a steady RC-then-final cadence, and two threads dominate the last month. The first is presence: custom user status has been landing piece by piece across releases — member list, room header, autocomplete, room summary — and now includes on-a-call state that users can set and clear themselves. The second is a module system, which reached v1.0.0 across four separate modules in early August and keeps gaining API surface.
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.
Element vs mailcow: editorial side-by-side
Element
5.0COMMS
Element Web is opening an extension surface while rebuilding its timeline underneath.
◆ Current state
Element Web ships on a steady RC-then-final cadence, and two threads dominate the last month. The first is presence: custom user status has been landing piece by piece across releases — member list, room header, autocomplete, room summary — and now includes on-a-call state that users can set and clear themselves. The second is a module system, which reached v1.0.0 across four separate modules in early August and keeps gaining API surface.
◆ Where it's heading
The module work is the more consequential of the two. Banner, Widget Toggles, Widget Lifecycle, and Restricted Guests all hit v1.0.0 on the same day, and the following release adds a Module API for storage helpers plus a dedicated modules docker image — infrastructure for deployments to extend the client rather than fork it. Alongside that, Timeline MVVM has begun as a shared TimelineView, which reads as the opening step of a longer architectural refactor. Individual releases stay incremental; the pattern across them is Element Web becoming a platform its operators configure.
◆ Prediction
Expect Timeline MVVM to arrive in numbered stages across coming releases, and the Module API to keep widening beyond storage helpers as the four v1.0.0 modules run into what they can't yet reach.
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.
