Feature.fm allows you to seamlessly sync the emails and other fan data you collect to a designated mailing list in Mailchimp or ActiveCampaign through the Integrations page.
To setup email integration, log into your Feature.fm account and click on the drop-down in the upper right-hand corner of your account. Select Integrations.
From the Integrations page, you can enter your Mailchimp and/or ActiveCampaign API keys. Be sure to first toggle the switch over to enable API Key entry. Check out this article on how to create and find your API Keys and other relevant info.
