As you may or may not know already, we're members of MAAWG, the Messaging Anti-Abuse Working Group. As part of our participation in that group, we're working to help develop the next version of MAAWG's “Sender Best Common Practices” document. Meant for email service providers, their clients (folks like you), and other senders, the goal is to provide clear and detailed guidance on list management and email delivery practices.

In the mean time, I'd recommend taking a look at the current Sender Best Common Practices document. In it, you'll find guidance on what it means to obtain clear and conspicuous consent, how to make it easy for end recipients to unsubscribe, how to manage email delivery issues, list hygiene and maintenance, blocking issues, etc.

It can be a bit of a dry read, but if you're looking for where to begin on how to do things right, this is where you start.

As always, if you have any questions, feel free to contact our deliverability team at deliverability@exacttarget.com and we'll be happy to help.
