New/Mode now has an easy way to set up a Mailchimp Integration!
Step 1: Head over to your New/Mode dashboard, and select the Integrations Tab
Step 2: Find Mailchimp from the grid of integrations, and select “Add Integrations”
Step 3: Enter the Title of your Mailchimp Integration, and scroll down to the Mailchimp Settings
Step 4: Enter in your API Key (In your Mailchimp account, click on your name, select Profile > Extras > API keys, then copy an existing one or create a new one).
Step 5: Enter in your Audience ID (In your Mailchimp account, open the Audience tab, click View Contacts > Settings > Audience name and defaults, and take the string of letters and numbers from the Audience ID section).
Step 6: Enter in your Host. This is in the format 'https://<domain>.api.mailchimp.com/3.0/', where <domain> is the characters after the dash in your API Key (in the screenshot above it's "us12").
Now Mailchimp is set up. To edit which components will sync to Mailchimp fields on a tool, head over to the tool, and navigate to advanced -> CRM Integrations.
