Facebook Postmaster page

There’s still quite a bit of concern and worry about how the Facebook messaging platform is going to affect marketing. One thing that may help is the Facebook postmaster page. There’s all sorts of good information on those pages, reflecting the years of experience that their messaging team has in running large platforms.
Some points worth mentioning.

• Facebook is giving detailed response codes allowing senders to identify technical problems and policy problems. They’re also giving time frames for how long policy problems might last.
• Facebook is requiring some sort of domain authentication to send mail. While they are not outright rejecting unauthenticated mail, they are reserving the right to deliver unauthenticated mail slower than authenticated mail.
• Facebook is not promoting the use of their messaging system for bulk mail. Based on Zuc’s announcement, this shouldn’t come to a surprise to anyone. This also means they’re not providing any resolution services for delivery problems. They’re also not providing a feedback loop.
• Facebook is not accepting mail from dynamic IP addresses, and are using the PBL as one part of that screening.
