What is Simon Data?

Simon Data is shipping integration after integration — Movable Ink Da Vinci, Rokt, Criteo semantic matching, Amazon Ads.

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.

OpenEMM vs Simon Data: editorial side-by-side

OpenEMM
MKT AUTO
5.0

OpenEMM opens a 26.11 beta, still without notes on what changed.

◆ Current state

OpenEMM published a beta of its 26.11 line on November 4, with frontend, backend and runtime all at 26.11.136. The 26.05 line it will replace reached GA in July and has had only frontend builds since. No entry describes actual changes.

◆ Where it's heading

OpenEMM keeps a twice-yearly line cadence (xx.05 and xx.11), with a beta, then GA, then maintenance builds. The release feed confirms the schedule but not the content of each line.

◆ Prediction

Expect 26.11 GA within a few months on the pattern of earlier lines, followed by maintenance builds; what 26.11 changes is not visible in the entries.

Simon Data is shipping integration after integration — Movable Ink Da Vinci, Rokt, Criteo semantic matching, Amazon Ads.

◆ 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.
