For people who send email news letters from their own website verses outsourcing to a service such as MailChimp or Constant Contact, acceptance of these emails by major service providers such as Yahoo, Gmail, Hotmail, Comcast, and others is a very important concern. DKIM (Domain Keys Identified Mail) is a way of digitally signing your email to verify that it is in fact yours and not somebody else claiming to be you. For non technical people it's the equivalent of the wax seal the king put on letters in medieval times.
Whether or not these major carriers accept your mail or consider it spam is still up to them but by claiming responsibility for the message it is more likely that they will. If there are user complaints they know where to find the person that sent it. Further they assume you will make a conscientious effort not send unwanted email if you are taking full responsibility for it.
ADHD Media now offers this service for any sites hosted on one of our servers. Setup cost is minimal and a one time fee verses the ongoing monthly fees at outsourced companies such as MailChimp or Constant Contact. ADHD Media is one of the few smaller personal service web hosting companies to offer this service on outgoing bulk mail.
