How to get into Yahoo Inbox with your bulk emails

Feb 21, 2010 by Paul White

Yahoo runs one of the strictest Anti Spam setups of all the Free mail Servers.  If you send any kind of bulk emails then you likely haven't had much success getting into the inbox of yahoo.  Your Emails are either bounced with a deferred message like this Reason: Remote host said: 421 4.7.0 TS01 Messages from 69.80.230.7 temporarily deferred due to user complaints - 4.16.55.1. or they end up in the spam folder.  After switching IPs of my mail server I had the opportunity to validate many of my theories on how Yahoo's AntiSpam technology works.

ATT and Verizon DNSBL Problems.

Feb 13, 2010 by Paul White

Verizon and AT&T yesterday started bounced emails from my server.  This was very unexpected, as non of my websites do any kind of spam.  A few of them do send a newsletter but this is to a double Opt in Maillist.  Everyone getting the newsletter signed up for it.  So in this blog I will chronicle my journey to get this resolved with both ISPs.  If this turns out good, then fine. If it turns out bad, then at least I will have documented it for the rest of the world.

MX records being used to block spam

Apr 20, 2009 by Paul White

Recently I have noticed that the open rates of a few of my client's newsletters are going down.  This is leading me to believe that most free mail servers are using yet another litmus test to detect and block spam.  Unfortunately those of us with legit bulk emails campaigns are also feeling the pinch.
