DKIM stands for DomainKeys Identified Mail. DKIM adds a digital signature to your emails that verifies an email was sent from an authorized sender and hasn’t been altered in transit.
Manually setting up DKIM requires editing your domain's DNS records. If you're not comfortable making these changes, you can use Entri to automatically configure your DNS.
To get started, go to your Account tab, select Campaign Settings, and click on Domain Authentication.
On this page, enter your domain and subdomain (if applicable). Afterward, click the Add Domain button to proceed.
Once you've added a domain, our system will offer you instructions on setting up DKIM, SPF, and DMARC. The SPF record will be displayed on the left, DKIM setup instructions will appear in the middle, and DMARC information will be shown on the right.
In the middle section of the DKIM instructions, the first box shows your current DKIM record, updating periodically to reflect the latest status. The second box provides the text to add to your root DNS zone, and the final section contains the DKIM key for the IN TXT record. To easily copy the values from these sections, use the copy button located to the right.
After making the necessary changes, allow at least 10 minutes for the DNS updates to propagate. To check your records, click the Check Current DNS button to refresh the status manually. If the setup is correct, you’ll see green success messages confirming a successful installation. If not, verify that your DNS entries are accurate and fully propagated before trying again.
ReachMail recommends that customers implement DKIM, SPF, and DMARC for best results.
