Nimble and MailChimp Sync Overview 

One of the most popular PieSync integrations is keeping selected (marketing opted-in) Nimble contacts in sync with a MailChimp list.

Watch below for some common MailChimp and Nimble use-cases: 

Example Syncs 

Sync from Nimble to MailChimp. Nimble contacts that have opted-in to a mailing list will be synced to MailChimp. 

Sync from MailChimp to Nimble. New subscribers to your mailing list (e.g through a webform) will be synced to your Nimble contact list.

Note: MailChimp is very strict about the opt-in status of your subscribers, therefore, only sync those contacts of whom you have obtained express permission. In the following example, a tag in Nimble is controlling whether or not contacts get synced to MailChimp.

The rule comes with a handy toggle that completes the 2 way sync. This toggle works like this. Say you have a newsletter and you contacts opt-in to receive it. The contacts that have opt-in for your newsletter will get the tag "Newsletter" inside Nimble. 

If the contact no longer wants to receive the newsletter, simply removing the tag in Nimble and PieSync will ensure that this information is synced to MailChimp, and they will be unsubscribed in MailChimp. 

Syncing with custom fields

Custom Fields enable users to capture unique data that is specific to your business needs. When it comes to MailChimp, not all fields are supported in Nimble, however, you can create them using Custom Fields. By utilizing this integration, you will automatically keep your specially designed custom fields up to date.

Take the example in the .gif for instance. “Average Open Rate” is a field in MailChimp, but not a field in Nimble. After creating the field, it can now be selected as a mappable option for synchronization.

The ability to sync custom fields is available in PieSync’s Pro Plan which you can learn more about here:
