Want to know if that important email was actually read -- or ignored? These Gmail tools can help.
When
you send an email, it can sometimes feel as if you're tossing it into a
black hole. Did your recipient get it or was it waylaid by a faulty
spam filter? Was it ever read or did it get lost in the day's mass of
messages? The only way to tell is via email tracking, which lets you
know when your email is opened by its recipient.
