Cloud-based note service Evernote does many things well, like improve gifts, but its direct email functionality was always kind of lacking. Not so anymore, as you can tag and organise mailed-in notes using subject line character codes.
If you don't already know it, find out your "secret" Evernote email address by heading to Settings while signed into Evernote on the web, checking the Account Info box on your desktop client, or looking at the Sync tab of Evernote for iPhone. Once you've got it, you can add it to your address book and send it anything you want to add to Evernote — forwarded emails, full web pages from your desktop or mobile browser, quick notes you jot to yourself, whatever. To add a tag, put the pound/hash symbol (#) before it, like so:
Nancy Drew purse #gifts #wife
To put the note in a particular notebook, use the email-type "at" symbol (@), as such:
Nancy Drew purse #wife @gifts
Evernote states in its blog post that you can't create new tags or notebooks with these symbols — they have to already have been set up elsewhere — and that the title of your note should always go before your tag and notebook symbols. It's a great, if overdue, improvement for those who are more at home in email or SMS-to-email than on a smartphone, and for Gmail junkies who can now knock out a note before they forget it.
