Weve discussed blacklisting, I wanted to spend some time looking at where the rubber hits the road for email delivery: the ISP inbox.
Lets be very clear about this for consumer facing campaigns there are 4 major ISPs that manage the majority of consumer inboxes.
-> MSN/Hotmail
-> Yahoo Mail
-> AIM Mail
-> Gmail
What Does this Mean?
Basically unless each of these mail platforms relays your message to the primary folder, your email campaign is far from optimized.
What Causes mail to be delivered to a bulk/spam Folder?
All of these ISPs allow their users to report spam with a report spam button. The ISP uses this feedback to create a profile for your mail. If users are reporting your mail as spam you will run into problems.
What Can I do to make sure I do not create ISP Spam complaints?
AOL recommends keeping spam complaints below 1-3 percent of traffic, depending on volume. This figure is unique to AOL’s user base; it’s too generous when applied as a general standard. Be at or below the range of one complaint per 6,000 to 8,000 messages, or 0.013 percent.
