email marketing

Numerous DNSBLs compiled by independent groups are out for mail administrators and ISPs to purchase. These lists contain not only spam-sending emails but even emails sending legitimate messages. And what is so surprising is, you might be included in these lists. You can be blacklisted if your previous promotional emails have been flagged by content filters, disgruntled users, or algorithms that are beyond your control. This can happen even if you are a CAN-SPAM compliant.

Domains or IP addresses believed to send spam are placed in the email blacklist. These domains and addresses comprise the blacklist. Once you send an email, a software program will check if your message is a spam. This process has some degree of uncertainty, because the software only makes its “best guess” by evaluating the words in your subject line to the size of the font that you used, quality of graphics or quantity of message sent.

User Feedback and Email Blacklist Problems

Email blacklist can also be influenced by user feedback. This problem can occur in two instances. First, if your clients do not recognize you message as something they have signed in, then they would probably consider it as spam. The other instance is when you make it hard for your clients to get rid from your mailings. They can report your messages as spam if they want a quick way to undo their subscription.
