Mailchimp / Brevo Connector for Business Central

If you run newsletters in Mailchimp or Brevo but your customer truth lives in Microsoft Dynamics 365 Business Central, you are almost certainly maintaining two lists by hand: exporting CSVs from BC, cleaning them, re-uploading, and never quite trusting which audience is current. This connector closes that gap.

ECOSIRE builds you a per-tenant Business Central extension (AL language) that synchronizes your Customer and Contact records into your chosen ESP audiences and then feeds engagement data back onto the BC contact, so your sales and marketing teams see one consistent picture inside the ERP they already use.

What it actually does

• Customer/contact → audience sync over the ESP's REST API (Mailchimp Marketing API v3 or Brevo API v3), with field mapping you approve (name, email, company, country, language, custom merge fields/attributes).
• Sales-based segmentation computed from BC posted sales data — top buyers by revenue, lapsed customers (no posted invoice in N months), customers by item/category — pushed as tags or audience segments.
• Engagement back to BC — opens, clicks, last campaign, subscribe/unsubscribe status written to fields added via a table extension on Contact, surfaced through a page extension on the Contact card.
• Scheduled incremental sync through the BC Job Queue, so only changed records move on each run.
• Multi-list / multi-audience mapping for businesses running several newsletters or brands from one tenant.

Honest, build-to-order

This is not an instant AppSource download. After purchase, ECOSIRE scopes your field mapping and segmentation rules, builds the extension, installs it as a per-tenant extension on your BC environment, configures the ESP API credentials and Job Queue, validates the first sync with you, and supports it afterward. You get working software on your tenant plus the engineer who built it.
