Recently we have had a lot of complaints of email not being delivered, or bouncing back from the large ISP's ilke Yahoo, AOL etc, when sending out an email marketing blast.
Here is some useful information to help with deliverability.
Yahoo, AOL and other large ISP's control email delivered to there systems based on a number of factors, if you are not a spammer and are sending legitimate email from systems that are setup properly like ours here at K1 then the biggest factor is complaints. If your marketing emails are flagged as spam by only .22% or two people out of a thousand* then our entire system is prevented from sending email to this ISP for a unspecified amount of time.
To prevent your customers from flagging your messages as spam there are a number of things you can do. I found a good blog post on this "how to ruin deliverability in 10 easy steps" by Stephan Pollard a email marketing professional.
*AOL and Yahoo won't say exactly what percentage of messages need to be flagged, the .22% is based on Goodmailsystems.com standards for delivering to Yahoo and AOL.
