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
5.0MKT AUTO
OpenEMM 26.11 reaches GA eight days after its beta.
◆ Current state
OpenEMM released 26.11.169 as the general-availability build of the 26.11 line on November 12, eight days after the 26.11.136 beta. The notes list only the frontend version. The 26.05 line it replaces reached GA in July and has had only frontend builds since.
◆ Where it's heading
OpenEMM keeps its twice-yearly cycle: a beta, a GA, then months of frontend-only maintenance builds. The notes never say what a line changes, so the cadence is the only visible signal.
◆ Prediction
Expect frontend-only 26.11 maintenance builds over the coming months; the entries give no hint of feature content.
