Is your email marked as “Queued” in your outbox in Gmail?
If so, your email will not be sent to the recipient even though you have an internet connection.
Gmail has security, real-time notifications, and support for multiple accounts.
You can use it to send and receive emails, collaborate with others, video call, and more.
However, some users experience errors in the app like insufficient space and unsent emails.

Why is my Gmail email queued but not sending?
