Tried this, and one of the big difficulties is that I send email to my todo list manager to create todos ("pick up milk", "Email person about important_thing").

I don't want to give this up, but can't find an app that only sends email. So when I opened Mail to send a todo email, I'd see all the new emails that were begging to be read. I could create a new email account that I use for sending only, but that seems like a pain.

Anybody seen an iOS app that sends email, but doesn't check it?
