It's a good idea, yet, it's risky. You could lose your gmail account.
There are many things that can happen and you'll never get that email.
So, I'd suggest that people try this with a small amount of money, so it doesn't end in sorrow.
There should be more efficient ways to execute this idea.
Why not send it to multiple email addresses you own?
Set a notification on your phone or computer, send it 6 months to 1 year out to keep your self in the loop and constantly repeat the process?
