We've been working hard over the last few months to make improvements to our newsletter deliverability rate. We've added two major enhancements which we believe will significantly enhance the deliverability of your email newsletters.
- DKIM - DomainKeys Identified Mail is a method for email authentication that allows you to take responsibility for the email newsletters that you send in a way that can be validated by a recipient. Large email providers such as Yahoo and many others rely on this technology to validate your newsletters and allow for a more timely delivery
- List-Unsubscribe Headers – This feature will add a "list-unsubscribe" header to your outgoing email marketing emails. By doing so we enable ISPs to add an unsubscribe link or button into their user interface. That way, readers who want to unsubscribe, but can't be bothered with locating the unsubscribe link in your email, can do so without clicking the "Spam" button in their email clients which in turn affects your deliverability rates
