I am looking for the best process to have a user input their email address and receive a downloadable PDF in their email inbox. The main problem I'm having is being able to send it to users that are already subscribed to our mailing list.
I was hoping to embed a MailChimp form into the product page, have a user input their email address, click the download link. From there, the user is tagged in Mailchimp and an automatic email is triggered. The MailChimp form won't let users who are already on our mailing list hit the download button (it sends them to an "update your contact preferences").
