Setting the Sender Domain for Bulk Email

By setting the domain authentication setting (SPF authentication, DKIM authentication) for bulk email, you can show that emails are sent from a Sansan-managed server. This setting prevents the target recipient from seeing a message such as "sent via". This reduces the chances of your mail going to the recipient's Spam folder.


Key Points

  • Use of this function requires administrator access.
  • Some records need to be registered in the DNS of the target domain you are using. Consult with your network administrator for specifics.



Checking DNS records

  1. Click [Admin Settings] > [Domain Settings].
  2. Enter [Sender Domain].
  3. Register the displayed records in your domain in [DNS Settings].


Registering DNS records

Add the records indicated in the above step 3 to the DNS of your domain. It may take up to 48 hours for this to take effect.
Consult with your network administrator for specifics about registration.


Enabling DNS records

After confirming that the records are effective in the DNS, return to the domain authentication setup screen and click the "Verify" button. If the settings are correct, the status will be "Active".


Deleting the domain

Select the target domain and click "Delete".
