You can export your affiliates to a CSV file and upload them to an email marketing platform (ie. MailChimp).
It is also possible to automate this process, and add every new affiliate who joins your program to a mailing list in MailChimp using a Zapier integration. Sendpulse also offers an integration with Tapfiliate through Zapier.
We believe in a "marketing stack” approach. This means, we focus on our core functionality and try to make it as easy as possible for you to integrate with other products.
