What Is Causing This Error?
When using an SMTP plugin with SendGrid mailer and you encounter the ‘The from address does not match a verified Sender Identity’ error, know that the issue originates from SendGrid.
Essentially, when setting up a sender on SendGrid, you need to verify ownership of a single email address to use as a sender. SendGrid would have sent you a confirmation message with a link to finalize your Single Sender identity setup. By not confirming through that link, the system doesn’t recognize your sender as valid, hence the error.

To fix the ‘The from address does not match a verified Sender Identity’ error, you’ll need to verify ownership of the email address you’re going to use as a sender in SendGrid.
