A Beginners Guide to ISP Inbox Delivery
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

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.
Minimize Complaints
Minimizing complaints always starts with practices used to collect e-mail addresses. It should be obvious by now sending unsolicited e-mail only gets you in trouble. Mailing lists with the lowest complaint rates are either confirmed opt-in or properly managed single opt-in. If you have a solid permission-based list but still find incoming complaints are higher than the optimal rate or are rising, consider the following:

-> Consider including unsubscribe instructions at the top of your e-mail, in addition to the footer. Some users use the “report spam” button as an unsubscribe method and won’t scroll through an entire message to find that link.
-> Include instructions for users to whitelist your domain. This prevents a user-based filter from mistaking your message for spam and either diverting it to the spam folder or prefixing “[SPAM]” to the subject of the message.
-> Provide a preference update page. Disclose how your organization will use a subscriber’s e-mail addresses, and how often. Allow subscribers to select preferences on the opt-in form, and link from e-mail to a preference or profile update page.
-> Avoid spammy looking content. Try not to use garish, bold fonts; large, red letters, and the like. Avoid images with poor compression quality. A clean, readable design isn’t as likely to be mistaken for spam.
-> Don’t over e-mail. If recipients expect to receive a few informational e-mail messages each month from your company, don’t suddenly start sending two or three each week.
-> Don’t send unexpected e-mail. If subscribers opted in to receive your “Trends & Tips” newsletter, don’t send them your hard-sell e-commerce messages, unless they clearly requested them.
-> Include opt-in information. If possible, add to your e-mail admin area information, such as the subscriber’s e-mail address, date of opt-in, and how she potentially subscribed (product registration, white paper download form, sweepstakes entry, etc). With many subscribers receiving dozens of commercial e-mail messages daily, it’s easy to forget signing up for your newsletter — and then https://greenthoughtsconsulting.com/murfreesboro-marketing-services/ to file a complaint.
