Remove me from your mailing list.

If you are sending out newsletters, here's some advice:

Make it very easy to unsubscribe.

Here's why:

1. It's just common decency.
2. Users will not appreciate your lock in tactics, and it will tarnish your brand.
3. Since it's hard to unsubscribe, they'll just mark you as spam.

If you require me to log in to unsubscribe, I'm marking you as spam.
If there is more than 1-2 steps to unsubscribe, I'm marking you as spam.

Ideally, put a link at the bottom of the email that says "unsubscribe". When clicked, it optionally asks, "are you sure?", and then unsubscribes the user. No fuss, no muss.
