How to gmail yourself
I've noticed recently that when I send myself an email note, it shows up as a sent message but never hits my inbox. So I need to remember I was reminding myself of something. Not very bueno.
Here's the fix: Create a filter for messages from yourself and tell it that messages that match this search should never be sent to spam.
Messages to yourself weren't actually turning up in the spam folder, but the two seem to be related in some way.
Now then, if I could just figure out how to teach it that I never want to reply to myself in a conversation thread. I thought sure it used to be good at that.
Turns out, this was also capturing mail I sent to anyone and dropping it in my inbox. You might have better luck putting your own address into both the from and to fields, or if you're working from a catchall address, '*@example.com'
