Trustifi admin portal

Step 1 – Verifying the plan and user type

⚠ NOTE! In case you aren’t running under the “Pro” plan and your user type isn’t an “Admin”, you will have to upgrade your plan to “Pro”.

Navigate to "My Plan" page, verify that your plan type is "PRO" and your level is "Admin".

Verifying your plan details

Step 2 – Navigating to "Domains" under "Outbound Management"

The email relay section will be locked because you have no verified domains yet.

To verify your domain, navigate to “Outbound Management” (Shield icon) and then click on the “Domains” tab to continue.

Step 3 – Adding a new domain

Now, we will need to add the domain used to send emails. Continue by clicking on the “Add Domain” button.

Step 5 – Verifying the domain

After adding the domain, you will have to copy and import the records to your DNS provider (e.g. DNS Made Easy, GoDaddy). Continue to the next step after all the DNS records have been imported to your DNS environment.

Adding a new domain

Note: You can also click on "Download records CSV" from the "Actions" menu to save these records as a CSV file.

Step 6 – Verifying the domain and navigating to the Plan Settings tab

After you have added all the DNS records to your domain, click on “Check if verified” to see if the status changes to “Verified”. Continue to the next step only if the domain has been verified.

Note: Depending on your DNS system, your domain may take up to 24 hours to update DNS records.

Then select “Pattern match” from the drop-down menu, enter “.*[@]domain[.]com$” (Without double quotes), instead of domain and com, replace with your domain’s name and your top-level domain (e.g. .net, .com, .org).

Click on "Test expression" to verify the pattern is correct (see next step).
