SmartSource endorses DKIM for email reputation authentication


Jason Sykes, SmartSource Director of Deliverability, reports that all email messages sent on behalf of SmartSource clients are DKIM certified. 


According to Sykes, “SmartSource has been a proactive leader in supporting email reputation certification.  We believe that all mailers should maintain their own email identities and those identities are crucial to successful email programs.”


Sykes continued, “Our role is to assist our clients in every possible way to establish and maintain email best practices using technology and consulting services.  DKIM message authentication is a critical part of our deliverability programs.”


DKIM (Domain Keys Identified Mail) was developed in partnership by Cisco and Yahoo and is currently supported by all major ISPs.  For more information on DKIM, go to
