The Email Marketing & Mailchimp Connector syncs both directions: CRM segments become Mailchimp audiences automatically, while campaign opens, clicks, and unsubscribes flow back onto ERP contacts with revenue attribution. For marketing teams running Mailchimp alongside the ERP who currently export CSVs in both directions and can’t answer what a campaign actually sold. Planned features include segment-to-audience sync with field mapping, automatic suppression of unsubscribes across both systems, campaign engagement data written to contact timelines, e-commerce order attribution to campaigns, abandoned-audience cleanup, tag synchronization for behavioral triggers, and ROI dashboards per campaign inside the ERP. This app is currently in development on the ECOSIRE build pipeline. It will ship first for Odoo 17, 18, and 19 simultaneously, with an ERPNext port following on the v15/v16 track — the same triple-version coverage as every live ECOSIRE app. One-time license, free updates within your major version.
