Campaign Monitor vs OpenEMM: editorial side-by-side
Campaign Monitor
5.0MKT AUTO
Campaign Monitor is publishing deliverability, migration, and agency-tooling content.
◆ Current state
Campaign Monitor's feed is email-marketing content — deliverability how-tos, a Mailchimp migration guide, and a January batch of agency tool and CRM roundups. No product releases appear in the window.
◆ Where it's heading
The mix targets switchers (Mailchimp migration), agencies, and deliverability-conscious senders. Output is sporadic, clustering in batches rather than a steady drumbeat.
◆ Prediction
Expect more migration and agency-focused content; product moves aren't visible in these entries.
OpenEMM
2.5MKT AUTO
OpenEMM ships versioned builds on schedule, with no notes on what changed.
◆ Current state
OpenEMM moved to its 26.05 line in July with a full frontend and backend GA build. Since then only frontend builds have followed (26.05.111 in September, 26.05.132 in October). Earlier lines (25.11, 25.04) got maintenance releases into December 2025. No entry describes actual changes.
◆ Where it's heading
The pattern is roughly two feature lines a year, then frontend-only builds and backported maintenance. The direction of the product can't be read from version numbers alone.
◆ Prediction
Another 26.05 frontend build in the next one to two months fits the cadence; the next major line's timing and content are unclear from the entries.
