I’m using a Mailchimp signup form integration (embed form) which I linked up to a Webflow form.
We’re giving out coupons for a free product which are automatically sent to their inbox via a Mailchimp + Couponcarrier.io integration. Problem is that we’re just sending one coupon per email adress, even if they try to enter their adress multiple times. This is controlled by Couponcarrier which prevents multiple coupons per email adress.
I can’t figure out a way to detect that their adress is already registered, directly at the signup stage. It would be perfect to be able to show a message that says their email is already registered and that they therefore won’t get another code in their inbox.
Right now the form submission just pushes in an email data update (via action URL in Webflow) at the customers already existing profile in Mailchimp. Customer then waits for a code that’s never going to come.
