While dealing with the issue of
Google workspace not receiving some emails then you need to check Google’s server. Google server might go down for unplanned or maintenance
difficulties. Users need to check Google workspace status and check whether
Gmail is currently down. When Google server is temporarily down then your email
wasn’t handled properly. In such situation, you need to ask sender to resend
the email back to you. Another troubleshooting test users can do is by sending an
email. You need to try sending two emails, one with Gmail account and another
one from email service like Outlook or Yahoo.
