We are pleased to introduce you today to a deliverability guru from the UK, Tim Watson of Zettasphere.

Here's an article Tim posted on his blog a couple of years ago about the factors scrutinized in the spam filtering process. While we have touched on many of these items in the past in this space, Tim's description is right on target and very helpful.

It's called "7 tips so you don’t burst your deliverability balloon" and you can read it here.

Remember... don't break that balloon!
