Verify email for FROM caluse in Deluge script

Verify email for FROM caluse in Deluge script

Hi! I'm trying to use the SendEmail function with Deluge Script in a Custom Function. I want to put a custom email address in the FROM clause. I've read that it has to be verified but I can't find the way in Zoho Books. We are already using the email address in Email Templates, but I was configured by another person and know we don't know if these addresses are verified. Is there any way to check that?

Thanks. Regards
