I believe it’s no longer the case. There was quite a bit of work done to convince them this was a bad idea.

Part of it was requiring senders to pre-register selectors. laura -- Having an Email Crisis? 800 823-9674 Laura Atkins Word to the Wise la...@wordtothewise.com (650) 437-0741 Email Delivery Blog: http://wordtothewise.com/blog
