Troubleshooting Campaign Emails Marked as Spam


    Outgoing campaign emails are marked as spam which reduces the chances of recipients receiving the email.

    Beginning with version 9.1.0, each user’s license type (e.g. Sugar Serve) determines what functionality is available as described in the¬†User Management¬†documentation. Please note that the Campaigns module is not available for Sugar Serve users.


    This issue can occur when using sendmail as your mail transfer agent. Emails sent via sendmail fail reverse DNS lookups because the “From” address’ domain will not resolve to the IP address of the server hosting SugarCRM. This is a standard test performed by most anti-spam filters. For more information regarding reverse DNS lookups see the following Wikipedia page:


    To resolve this issue, use a valid SMTP server, one that corresponds to the “From” address of the outbound emails, to send emails from Sugar. Changing this setting requires administrative privileges.

    1. From the Admin Panel, select the “Email Settings” link.
    2. In the Email Notification Options section, change the “Mail Transfer Agent:” drop-down to “SMTP” and fill the fields as required with the appropriate SMTP information. Contact your IT administrator if you need help filling in the SMTP information.
