I have a contact form on my website, but I’m not receiving any form submissions to my primary email address; they’re only being sent to the alias. My primary email, access@digitalpartner.no, works perfectly fine, and I receive dozens of emails there every day. However, form submissions are only coming through to the alias, post@digitalpartner.no.
That’s odd but it shouldn’t relate to the Webflow-end of the system.
I’d try a few things;
Keep the comma but switch your email order. That should not do anything, they should both receive separate email notifications, unless Webflow has made a change.
Change the comma to a semicolon, so that it’s a single submission with two recipients.
Those two tests are just for kicks to see if anything Webflow-side has changed.
Failing that, it would be an email-side problem. Make sure you haven’t filtered your messages, or they’re going to spam etc. Try whitelisting the sender, those types of things.
