Psst, Email Marketing? Get DKIM Now

DomainKeys Identified Mail (DKIM), a synthesis of email authentication work by Yahoo, Cisco, and other companies, holds a key advantage for email marketers beyond getting mail to recipients.

From time to time, news emerges on a company finding its usual email messages being treated as villainous rapscallions, denied entry to inboxes where they once arrived without incident. One day email's traveling without incident, the next day it turns into O'Hare Airport on a snowy holiday weekend.

One's email campaign doesn't need to suffer from an unnecessary blockage (we mean this for legitimate opt-in marketers; you spammers deserve intestinal blockages along with your email being stuffed). We give credit to Mark Risher, group product manager for DKIM Briefly, DKIM lets a mail server know an incoming message from a domain actually came from that domain. DKIM-capable mail servers check this and pass approved messages through.

Risher noted how in our piece about BITS recommended adoption of DKIM for financial institutions. That would go a long way toward restoring trust in email messages from banks, a regularly spoofed item by criminal phishers.
