MailchimpAdd/Update Subscriber

Rather than manually exporting iRefer sign-ups and importing into MailChimp, use Zapier to automatically add new sign-ups to your MailChimp list. Once you set up this MailChimp integration, new sign-ups from that point forward are added as subscribers.

How this iRefer-App MailChimp works

  1. Someone signs up to your iRefer campaign
  2. Zapier adds that sign-up to a MailChimp list

Apps involved

  • iRefer account
