Is your e-mail getting through?

Lets say you or your client use e-mail marketing. Let's say it's permission based marketing, and not just spam. You'd think that your emails are reaching your targets, right?

Think again. And it could be your ISP's fault.

emarketer.com writes that Return Path, an e-mail service provider, has studied 18 different ISPs and has found that some ISPs see as much as 37,7% of their emails are blocked (Netzero is the worst). The winner is Earthlink that sees only (!) 7% of their permission-based emails blocked.

The most common reason for non-delivery is that the target's ISPs identify the e-mail as spam (even though it's not) and either block the mail or send it to a junk mail folder.
