Mail Delivery Subsystem not working

[SeoYeong Lee]

Hi all, There's an issue with receiving an error message when there is a wrong email(not exist).

There's no problem with "Document Merge Status" column message when running the program. It just says "Emails sent: [To: not exist email]; Manually run by my email; Timestamp: ~~"

However, the email in that case was the wrong email(not exist).

When I sent the same email individually via g-mail, I got reply by the "Mail Delivery Subsystem" about the error that the email does not exist.

I need to check emails that have not been sent.

I used an email from an organization that uses Google Workspace products.

Thanks for your help.
