Shop email address UX improvement | Messages with multiple addresses in From: header are not accept
Clearer field separation or a warning if multiple addresses are set as the sender field for "Shop Email Address".
If multiple email addresses are used in this field, it can generate the following error message:-
"Messages with multiple addresses in From: header are not accepted."
Either it is necessary to have a separate field for ONLY receiving email notifications, where you can state multiple email accounts and a separate field for sending (single email address), or it is necessary to explain that some email servers will reject emails where multiple email addresses are used as the "FROM" field.
