◆ Current state
Simon Data's recent cadence is dominated by activation-channel reach. April 2026 added Movable Ink Da Vinci (AI-driven email orchestration via SFTP) and Rokt (e-commerce engagement audiences). Q1 2026 brought Criteo semantic email matching, custom base URL support for self-hosted MessageFlow and ExpertSender deployments, a 14-day send-or-click attribution window, credentials search, and a Redlink → MessageFlow rename. Earlier shipping included Oracle Hospitality as a data source, Privacy Request Expirations with configurable TTL, and Braze user-alias fallback.
◆ Where it's heading
Simon Data is positioning itself as the CDP that plays nicely with the broadest set of activation channels — including AI-driven ones like Movable Ink Da Vinci. The integration roadmap is working harder than the core product on the value story; that's defensible for a CDP, where each connector represents real revenue, but it suggests the platform itself is in maintenance mode while the integrations team carries the cadence.
◆ Prediction
Expect more AI-activation integrations (other generative-email vendors, retail-media platforms beyond Amazon and Rokt), continued attribution-window flexibility, and possibly a Simon-side AI feature that uses the customer-data graph to suggest segments — that would be the directional break from pure integration cadence.
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.
