Sync Marketing. Simplify Campaigns. See Results.
Connect Dynamics 365 and Mailchimp — and let your marketing data work smarter
Managing customer lists and campaigns across two systems should not be this painful.
Our Dynamics 365 + Mailchimp integration connects your marketing data automatically - no more imports, no manual lists, no missed updates. Just clean, consistent information that saves your team time and helps your campaigns land better.

What does this integration do?
Marketing teams often live in Mailchimp. Sales and service teams live in Dynamics. But your customer data lives in both - and it does not always match up. That is where our integration helps.
We have built a simple, reliable way to sync marketing lists from Dynamics 365 to Mailchimp - and bring engagement activity back the other way. You stay in control of your data, your lists stay aligned, and your teams stay on the same page.
This integration does not replace Mailchimp — and it does not try to.
You will still build and send campaigns from within Mailchimp. You will still use Mailchimp’s segmentation and analytics tools. What this solution does is make sure the right data is flowing in and out of Mailchimp at the right time — without anyone needing to manually move it around.
Key Benefits
Less Admin, More Marketing
No more juggling spreadsheets, re-exporting lists or chasing bounced emails. Your team gets back hours a week - and can focus on creating better campaigns.
One Version of the Truth
Dynamics becomes your single, central source of contact and marketing data. Everyone works from the same view - whether they are in Sales, Marketing or Customer Success.
Flexible for the Future
Need something bespoke? Circyl’s plugins and APIs give us the ability to tailor the solution around your business - now or later.
Smarter Insights, Faster Decisions
Because campaign activity is fed directly back into Dynamics, your teams can see what is working in real time - and act on it, without delay.
Quick to Deploy, Easy to Use
This is not a unique project – it is a purpose-built integration designed for Dynamics and Mailchimp that is customised to your business and your requirements. That means faster setup, less disruption, and fewer technical headaches.
How it Works
Our integration uses secure, proven Microsoft and Mailchimp technologies to create a seamless data bridge:
- Mailchimp API integration keeps lists aligned and updated automatically
- Real-time Webhooks feed campaign activity directly into Dynamics
- Custom-built Dynamics plugins manage the sync and tracking logic
- User-friendly interface inside Dynamics for easy connection and control
No guesswork, no middleware, and no code required to manage it day to day.
