Reduce Costs with Reduced Bounce Rates

Dundee Internet offers email list hosting.  Most of our customers are pretty savvy when it comes to email marketing.  We find when someone switches their ESP (Email Service Provider) to us, they typically see a reduced bounce rate; as we help customers identify and correct any mailing issues.  Bounced email seems to be among the many reasons for their change.   For example, one customer told us:

“I was sending emails once a week to a list of 97,000 members I had acquired through hard work and diligence. Everyone on the list is opted in.  Every new member receives a welcome letter series. They also have a place to go on my website to change their email address, interests and, yes, they can even suspend their account when needed.  It was going great until recently when a lot of emails were returned.

The returned emails or bounces have a code, supposedly indicating a specific reason why my mail is not sending.  I have these codes from the report my ESP provides.  They told me to use the codes to figure why my email is bouncing.  I’m completely puzzled with these error codes, I thought I’d try you guys out”
