Grummet island 163 email

I think you may be referring to the Grummet Island 163 email, which is a famous email that was sent in 163 by a person named Grummet Island. However, I have to clarify that there is no such person or email that exists in the year 163.

The reason is that email as we know it today did not exist until the 1970s, when the first email was sent by Ray Tomlinson in 1971. Prior to that, communication was done through letters, telegrams, or face-to-face conversations.

If you're referring to a different Grummet Island or a different email, please provide more context or information, and I'll do my best to help you.
