Steps for Third Party Sending an Email to DMH Staff

Third party users must first register with “Secure Mail” before they can send encrypted email to DMH staff.

  1. To register, send an email to regsecuremail@dmh.ca.gov with subject line Register. You will get a reply back from the DMH “Secure Mail” service with subject “Re: Register (#encrypt).” The following screen shot is an example of what you will receive

For subsequent emails, the third party user can go directly to the Secure Server using the following URL: https://securemail.dmh.ca.gov/ and log in using their email and password from step 2.



  • Secure email is stored for 60 days. The "Secure Mail" delivery notice includes a note at the bottom of the screen, which states the expiration date for the message.
  • Inbound secure email is received in standard email format, indistinguishable from regular email.
  • For any problems or questions please contact the DMH Headquarter's help desk at (916) 654-3445.
