Mautic vs Customer.io
Side-by-side trajectory, velocity, and editorial themes.
Mautic hardens security across three branches and lines up a feature-heavy 7.2.
Mautic is in a maintenance-and-hardening phase. The standout is a coordinated security release across three supported branches (7.1.2, 6.0.9, 5.2.11) fixing seven CVEs, including SQL injection in API contact filtering and an API v2 authorization bypass. In parallel, 7.1.3 cleans up campaign and email reliability bugs, and a 7.2.0 release candidate stages the next feature line.
The project is balancing three commitments: keeping older branches (5.2, 6.0, 7.0/7.1) patched for security, steadily fixing campaign and GrapesJS-builder reliability, and building 7.2 around transactional email, better bot detection, and PHP 8.5 support. It reads as the cadence of a mature open-source platform serving a broad installed base, not one chasing new categories.
The 7.2.0 RC points to a stable 7.2 GA next, carrying truly transactional emails, Matomo-based bot detection, and the GrapesJS builder improvements out of pre-release.
Design Studio becomes the one surface where every Customer.io message is built
Customer.io is consolidating message creation around Design Studio, its newer visual editor, and steadily retiring the classic drag-and-drop path. Recent releases add global styling, brand variants, an email review/readiness panel, and a no-code notification inbox — all authored in the same place. The in-app messaging surface is also maturing, now with dark-mode-aware styling across web, iOS, and Android.
The clear direction is Design Studio as the single composition layer for email, in-app, and inbox, with migration tooling to pull legacy content forward and quality gates (SpamAssassin scoring, link/image validation) built in. In parallel, Customer.io is threading its AI Agent and Salesforce sync templates into setup flows to cut configuration work. Expect fewer standalone editors and more capability folded into Design Studio.
Next moves likely deepen Design Studio: broader global-component reuse and further deprecation of the classic editor, plus more Agent-assisted authoring beyond Salesforce field mapping.
