Linking Mailchimp as a source

The Mailchimp connector can link lists, campaigns, reports, and contacts to PostHog.

To link Mailchimp:

Go to the sources tab of the data pipeline section in PostHog.
Click + New source and then click Link next to Mailchimp.
Next, you need an API key from Mailchimp. Go to your API keys settings in Mailchimp. Click Create A Key, give it a name, and copy the value of the newly created key. The key should be in the format key-dc (e.g., abc123def456-us6), where the suffix after the last hyphen is your Mailchimp data center.
Back in PostHog, paste the API key in the API key field and click Next.
On the next page, set up the schemas you want to sync and modify the method and frequency as needed. Once done, click Import.

Once the syncs are complete, you can start using Mailchimp data in PostHog.
