Christine Borgia has a post on the Return Path blog where she interviews a number of different groups (spamfilters, DNSBLs, mailbox providers) about their filtering strategy for the holidays. Overall, no one changes their filtering during the Holiday Mailing Season. On the other hand, many marketers do change their marketing strategies in ways that trigger more filtering and blocking.
The take home message? Pay attention to what is being sent and who it is being sent to. This is nothing new, but many marketers seem to forget it in the effort to get into their customers’ inboxes.
