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 derivability rates
