Mailjet vs Neos CMS
A side-by-side editorial comparison of Mailjet and Neos CMS — release velocity, themes, recent moves, and the top alternatives to consider.
Mailjet vs Neos CMS: at a glance
What is Mailjet?
Mailjet is publishing deliverability compliance guidance, and little else.
A low-cadence blog — ten posts spanning eight months — weighted toward authentication and regulatory change rather than product. The substantive entries are two treatments of the CNIL and Garante tracking-pixel guidance in France and Italy, and a DMARC post that states a real product default: Mailjet is DKIM-first. The rest is competitive migration content, a platform comparison still labelled 2025, and research published under the sibling Mailgun brand.
What is Neos CMS?
Neos is rebuilding how its content repository commits and locks, one 9.2 beta at a time
Neos is a PHP content management system whose 9.x line runs three streams at once: 9.0 and 9.1 maintenance releases carrying the same backported fixes, and 9.2 betas where the real work happens. The feed stores these releases as bare tag lines, so what is in them is only visible at the source — the current beta's 32-character body conceals roughly 3,400 characters of notes. Those notes cover the event-sourced content repository: atomic commits, locking, event migrations and structure adjustments.

Mailjet is publishing deliverability compliance guidance, and little else.
◆ Current state
A low-cadence blog — ten posts spanning eight months — weighted toward authentication and regulatory change rather than product. The substantive entries are two treatments of the CNIL and Garante tracking-pixel guidance in France and Italy, and a DMARC post that states a real product default: Mailjet is DKIM-first. The rest is competitive migration content, a platform comparison still labelled 2025, and research published under the sibling Mailgun brand.
◆ Where it's heading
The positioning is compliance-and-deliverability first, which is the pitch of an infrastructure sender rather than a campaign tool — the transactional-plus-marketing post argues exactly that, against teams running two platforms. The Mailchimp migration guide and the comparison roundup point at where Mailjet expects to win customers: cost and consolidation, not features. Nothing in the window describes a shipped capability.
◆ Prediction
More regulatory response content is the safest read, since two of the last ten posts already cover the same EU pixel guidance; on product direction this source is silent and a release feed would be needed.

2.5MARKETING
Neos is rebuilding how its content repository commits and locks, one 9.2 beta at a time
◆ Current state
Neos is a PHP content management system whose 9.x line runs three streams at once: 9.0 and 9.1 maintenance releases carrying the same backported fixes, and 9.2 betas where the real work happens. The feed stores these releases as bare tag lines, so what is in them is only visible at the source — the current beta's 32-character body conceals roughly 3,400 characters of notes. Those notes cover the event-sourced content repository: atomic commits, locking, event migrations and structure adjustments.
◆ Where it's heading
The 9.2 line is reworking the content repository's concurrency model rather than its surface. Atomic events with commitAll remove content stream closing as a locking mechanism, global locking moves into the event store adapter, and follow-up migrations exist for workspaces rebased against content streams that no longer close. Alongside that, a crupgrade:eventsstatus command lets operators see which event migrations apply to their installation — which is the tell that upgrades from earlier 9.x versions are expected to need work.
◆ Prediction
Removing content stream closing changes upgrade behaviour for anyone with rebased workspaces, so expect the remaining betas to be mostly migration coverage and race-condition fixes rather than new features before 9.2 goes final.
