Mailchimp Connector for Dynamics 365

Key Features

Bi-directional contact sync between Business Central Contacts and Mailchimp audiences, keyed on email with configurable conflict resolution

Tag sync in both directions, with governance rules so BC categories and Mailchimp tags stay aligned

Map CRM/BC marketing segments to specific Mailchimp audiences via a configuration page (table-extension backed)

Pull open, click, bounce, unsubscribe and per-campaign stats into BC and display them on the Contact card via page extension

Create and schedule Mailchimp campaigns from within Business Central against a chosen audience

Field mapping UI for Mailchimp merge fields ↔ BC contact fields, including custom fields

Dedup controls — email-based matching plus pre-sync duplicate detection to prevent double subscribers

Job Queue–driven incremental sync on a cadence you set (e.g. every 15 minutes), with manual on-demand sync

Event subscribers on contact insert/modify queue only changed records, keeping API calls and rate-limit usage low

Sync log and error table with retry handling and per-record status for full auditability

Dedicated permission set scoping configuration and sync-trigger rights

OAuth/API-key credential storage in isolated storage, with subscriber-status handling (subscribed, unsubscribed, cleaned)

About this Product

Mailchimp Connector for Dynamics 365 is a build-to-order extension for Microsoft Dynamics 365 Business Central, written in AL and delivered as a per-tenant extension installed directly on your environment. It is not an instant AppSource download — ECOSIRE scopes it to your audiences and field model, builds it, installs it on your sandbox first, then promotes it to production with you.

The connector establishes a two-way sync between Business Central Contacts (and CRM marketing segments) and Mailchimp audiences. New and updated contacts flow to the right Mailchimp audience; subscriber status, tags, and merge fields flow back into Business Central. Engagement data — opens, clicks, bounces, unsubscribes, and per-campaign stats — is pulled into BC and surfaced on the Contact card via page extensions, so your marketers see Mailchimp activity without leaving the ERP.

Under the hood it uses table and page extensions to add mapping and engagement fields, event subscribers on contact insert/modify to queue changes, and a Job Queue entry that calls the Mailchimp Marketing API on a schedule you control. Outbound sync respects your field mapping and dedup rules (email-based matching, audience-to-segment mapping, tag governance) so you don't duplicate subscribers or overwrite curated data. A dedicated permission set scopes who can configure the connector and trigger syncs.

Optional Dataverse / Power Platform alignment is available where your CRM marketing lists live in Dataverse rather than native BC. Because it's your own per-tenant extension, the code, the mappings, and the sync cadence are yours — and ECOSIRE supports them. Pricing is a one-time USD 249 build; installation and the support window are included.

Who this is for

Marketing Operations Manager

Runs campaigns in Mailchimp but needs the audience to stay current with the D365 CRM contact base — and wants engagement visible to sales without manual CSV exports.

Business Central Administrator

Owns the BC environment and wants a clean per-tenant extension with a scoped permission set and Job Queue, not a fragile manual integration or an opaque third-party app.

Sales / CRM Lead

Wants to see who opened and clicked recent campaigns directly on the Contact card so follow-up is timed and informed.

Frequently Asked Questions about Mailchimp Connector for Dynamics 365

Is this an instant download from Microsoft AppSource?

No. This is a build-to-order, per-tenant AL extension. ECOSIRE scopes it to your Mailchimp audiences and Business Central field model, builds it, installs it on your sandbox for validation, then promotes it to production with you. There is no public AppSource listing to download.

How long does delivery take?

Typical lead time is 1–2 weeks from when we receive your Mailchimp API access and a short mapping brief (which audiences map to which segments, which fields, tag rules). Simpler one-audience setups land faster; heavier custom field mapping or Dataverse alignment can extend it. We confirm a firm date after the scoping call.

How does the two-way sync avoid duplicates and overwriting data?

Sync is keyed on email with pre-sync duplicate detection. You define field-level conflict rules (which side wins per field) and tag governance, so curated Mailchimp data isn't clobbered by BC and vice versa. Only changed records are queued via event subscribers, keeping API usage within Mailchimp rate limits.

What about ongoing support and updates?

The one-time build includes an initial support window for fixes and tuning after go-live. Because the extension is yours per-tenant, ECOSIRE can also provide ongoing support and adapt it as your audiences, fields, or Business Central version change — quoted separately as an optional retainer. You retain the source code either way.

Does it work with Dataverse / Power Platform marketing lists?

Yes, where your marketing lists live in Dataverse rather than native BC, we can align the connector to read from Dataverse via the BC–Dataverse integration so the same engagement and tag data still surfaces in Business Central. This is part of scoping and may affect lead time.

Will it survive Business Central upgrades?

It is built as a standard AL per-tenant extension using table/page extensions and event subscribers — the supported extensibility model — so it upgrades cleanly with Business Central. If a Microsoft platform change ever affects an API surface, support covers the adjustment within your support window.
