Make sure your emails are received

A lot of people new to email marketing express concern about their mailings being delivered as spam or worse having their site shut down by ISPs. Those are justifiable concerns. Even if your subscribers are opted in and your mailings contain unsubscribe links someone could still report you as spam. The following articles will help you understand the key areas of email deliverability and help ensure your emails are delivered.
  • Blacklists
    Learn how to check the blacklists and how to request removal from any blacklist you are listed on.

  • Sender Policy Framework (SPF) Records
    Sender Policy Framework (SPF) is a record that allows you to determine which computers can send emails on behalf of your domain. Improve email delivery rates by reducing the chance that the emails you send will be seen as spam.

  • DomainKeys Identified Mail (DKIM)
    An enhanced authentication standard that allows a person to verify that a message comes from the domain that it claims that it came from. All outgoing emails are digitally signed with a private encryption key to match a public key that is published in the sender’s DNS record. Used by Gmail, Yahoo, SBCGlobal, British Telecom, Rogers Cable, Rocket Mail, etc.

  • Sender ID
    Is very similar to SPF record except this extends the verification process to include the purported responsible address included in the header. Used by MSN/Hotmail

  • Feedback Loops
    A feedback loop is a service provided by ISPs where they will forward complaints made by email recipients to the original sender

  • Sender Reputation
    In essence, your sender reputation indicates to ISP the trustworthiness of the source of the email that is being delivered.    What constitutes a trustworthy source will vary from ISP to ISP.
