Today MediaPost ran this article, When ‘Best’ Practices Become ISP Law, commenting on many of the best practices and requirements that are published by ISPs and their required sending practices for mailers. As with most best practices they gradually become common practices, and then requirements.

The list includes the following items (all of which we have touched on in the past):

  1. Use double opt-in subscription
  2. Don’t pre-check the subscription box
  3. Authentication
  4. Purchasing lists
  5. List hygiene

A handy list of ISP Postmaster and security pages are also included, we recomend you review these on your own and ensure your program conforms to each of the respective requirements.
