Port87 is an email service that automatically organizes your email based on the "To" address.
If you give the address "yourname-netflix@port87.com" to Netflix, then all of their email will go in the "netflix" label in your account. This lets you organize your email when you give out your email address. It also prevents phishing, since an email from "Bank of America" in your "netflix" label is obviously phishing.
Labels meant for human senders, like the "friends" label (yourname-friends@port87.com), can be set to screen senders, so Port87 will respond to any new senders with a link to click to prove they're a human.
Your "bare address" (yourname@port87.com) only responds to emails with a list of your public label addresses, so you can share it all over the internet without fearing spam. (For example, mine is hperrin@port87.com.)
Full disclosure: I created and operate this service.
