Integration: MailChimp Dynamics 365

Hello,

I would have one question. We have a request from our customer to find the tool which would be able to integrate MailChimp with Dynamics 365. I have already tried Marketing4Dynamics from Inogic, SyncApps from Cazoomi, and PowerMailChimp. But none of these meets all the requirements.

Mandatory requirements:

1. (CRM -> MailChimp) When adding or updating new contact in CRM it would send the data to MailChimp
   1. Conditioning is required – that means that IF we have the contact in MailChimp then we UPDATE it, IF NOT then we ADD it
2. (Mailchimp -> CRM) When adding a new contact to the MailChimp audience it would send the data to CRM
   1. checking: IF contact mail is in the CRM, do nothing (as the contact in CRM might be more correct) … if it is not in CRM,  ADD the new contact to MailChimp
3. It is important to be able to TAG (ideal scenario SELECT a TAG from available tags - if not present create a new one) as we are utilizing tags in our audiences (so we do not have duplicates)

Nice to have:

1. It would be good (but not mandatory – mostly useful when adding new contacts to MailChimp -> CRM) to send ADRESS, COMPANY, TEL NUMBER

Do you know about any tool that meets all the mandatory requirements, and, ideally, also the additional fields mapping?

Thank you.

Jan
