RE: Multiple email address field on an account
Hi Kim,
The fields you mentioned has been set as format = Email by default and cannot be modified.
This is shown in the app by clicking on the envelope button after this field to create an email directly.
It is an OOTB designer which cannot be customized.
If you insist on merging all email addresses, create a new field to enter it directly or merge existing email address fields as its value.
If this helped you, I'd appreciate it if you'd mark this as a Verified Answer, which may in turn help others as well.
Best Regards,
Nya
