Bulk Email Deliverability Issues

Keys Identified Mail (DKIM) – Domain Keys Identified Mail I an email authentication method that is independent of the SMTP service. This service adds a header to all email that is sent from your server that has a key in it. The receiving server, if then set up to recognize DKIM, will do a DNS lookup with the key on the header to make sure that the email originated from your server. With this method, the receiving server can be sure that the email they are receiving is not forged by someone else and can set up filters to lower any spam scores to help the email avoid any automatic spam tagging. Use Sender Policy Framework (SPF) - Sender Policy Framework allows an email server administrator to give the means for other servers to verify that a server is authorized to send email for a certain domain. This is done by using a TXT DNS record that lists the authorized senders for that domain. The receiving sender can then decide to either reject the email based on a failure or apply a certain score that in combination with other factors will either mark your email as spam or not. Get into the Yahoo Whitelist - Yahoo has a certain procedure in place that will get companies that qualify into an internal whitelist.

This allows emails from these companies to go into the customer’s inbox instead of the spam folder. There are a lot of things that Yahoo require for you to get into their whitelist and it may take some time for them to review your qualifications. But if you qualify and get into their whitelist, it is well worth the wait to insure that your emails get into your mailing list’s inboxes.

Get into the AOL Whitelist – Like Yahoo, AOL has a similar system whitelist that you can get on. They have a different set of requirements and criteria from Yahoo, but being on their whitelist is worth the trouble. Create a Sender ID Framework - Microsoft is also involved in email authentication because of the prevalence of Hotmail, MSN, and Live users. Creating a Sender ID Framework is then very important and can help you with your email marketing campaign.
