Connecting Raiser’s Edge NXT to Mailchimp
To establish a consistent, robust connection between Raiser’s Edge and Mailchimp we connect Constituent records in Raiser’s Edge to the matching Contact in Mailchimp by using the Raiser’s Edge Constituent ID.
![Mailchimp Merge field](https://www.smartthing.org/wp-content/uploads/2021/04/KB_cons_id_screenshot.png)
The Constituent ID is passed to *|MERGE1|* or *|MERGE2|* in Mailchimp. This requires moving either the First Name and Last Name as these values reside in *|MERGE1|* and *|MERGE2|* by default.
The SmartTHING team can help you with this if required.
Subscribe & unsubscribe – Raiser’s Edge NXT Consent
When your Mailchimp contacts subscribe or unsubscribe from your Audience SmartMAILCHIMP will automatically add the correct Consent records to your Raiser’s Edge NXT database.
