Then do this...
MailchimpAdd/Update Subscriber

Rather than manually adding email addresses to your MailChimp list, use Zapier to start automatically adding new email addresses to your list. Once you set up this Email-MailChimp integration, new emails automatically forwarded to your custom Zapier email address from that point forward are individually added as subscribers.

Note: This Zapier integration doesn't add senders from previous emails into MailChimp—only senders of new emails after you've set it up. Emails must also be automatically forwarded (using Gmail filters or Outlook rules) to your custom Zapier email address. If you manually forward emails then your email address will be added to the MailChimp list and not that of the original sender

How It Works

  1. A new email is received by your custom Zapier email address
  2. Zapier adds the sender to a MailChimp list as a subscriber

What You Need

  • Email account (e.g. Gmail or Outlook)
  • MailChimp account
