Gmail is one of the most popular email services without any flaws. But sometimes users deal
with the issue of
Gmail not sending emails with attachments. If you are facing the same issue then start by switching off the firewall. It is possible
that firewall on PC is blocking email when you are trying to send. To disable
the firewall, proceed to control panel > network > system and security and
choose Windows defender firewall. After that, you need to clear browser cache
and cookies. Some temporary files stored in cache might keep email from getting
sent.
