I supposed I could do takeout and then just grep through the messages for the part of the message I remember. But that seems like overkill.
Is there a service out there that will index mail messages sent to/from gmail and allow you to search them? That would be a cool product.
The obvious solution is to call my mom, but I don't want to admit I didn't write her address down (instead assuming gmail would maintain it.)
Sure! What's your email and password? I'll help you.
