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 is going all-in on Europe's sovereign-comms thesis, with both customers and rhetoric to back it.
Element has narrowed its public posture almost entirely to one buyer: European governments and regulated organisations that want a Matrix-based, self-hostable alternative to US consumer messengers. The last two months blend concrete shipping work — Spaces on Element X, an ESS Community migration tool, MatrixRTC progress — with a steady drumbeat of policy commentary on CRA, the Digital Omnibus, and Signal/WhatsApp targeting incidents. The Meedio deal anchors the strategy with a real customer building a sovereign comms platform on ESS Pro.
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
0.8COMMS
Element is going all-in on Europe's sovereign-comms thesis, with both customers and rhetoric to back it.
◆ Current state
Element has narrowed its public posture almost entirely to one buyer: European governments and regulated organisations that want a Matrix-based, self-hostable alternative to US consumer messengers. The last two months blend concrete shipping work — Spaces on Element X, an ESS Community migration tool, MatrixRTC progress — with a steady drumbeat of policy commentary on CRA, the Digital Omnibus, and Signal/WhatsApp targeting incidents. The Meedio deal anchors the strategy with a real customer building a sovereign comms platform on ESS Pro.
◆ Where it's heading
Product work and policy work are now reinforcing each other rather than running in parallel: every shipped feature is framed as evidence that decentralised, federated comms can meet government-grade requirements. The migration tooling and Spaces in Element X point at a concerted push to make ESS deployable enough that procurement teams will sign. Expect Element's editorial output to keep using competitor security incidents to harden the case for Matrix in regulated markets.
◆ Prediction
Look for another EU-government deployment announcement within a quarter, alongside continued Element X feature work aimed at making the client feel competitive with WhatsApp for everyday users — Spaces was the precondition, threads and call quality are the obvious next slabs.
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.
