What is the Email Deliverability tool?

This tool makes it possible to identify any problems with your DNS records related to email for all domain names added to your cPanel plan. In fact, this system uses these records to verify that other servers can trust it as a sender.

How do I use the Email Deliverability tool? 

To access the Email Deliverability tool, log in to your cPanel interface and click on "Email Deliverability" located in the "Email" section.

The email deliverability table lists your domains, provides their DNS record status, and allows you to manage DNS records related to email.

You can click the "Manage" button located behind the relevant domain in order to manually configure the email-related DNS records. The top of this new page will display the following information:

DKIM configuration

This section allows you to manage a domain's DKIM record, verify the sender and the integrity of a message. In addition, it allows the mail system to ensure that spammers have not modified an incoming message during transit. Lastly, this key makes it possible to verify that emails received by your domain actually come from the specified domain.

To install a DKIM record correctly, your server must be the authoritative nameserver.

  • Full: The record will be displayed in full. This option is intended for providers that automatically split their records.

Important :

Exposing your DKIM private key can be a security issue. In fact, if other people obtain your key, they would be able to sign emails while pretending to be you. Therefore, only provide the DKIM key to trusted people.

SPF configuration

This section allows you to manage a domain's SPF record. This area checks that messages sent by your domains come from a listed and authorized server. If any problems are present in this DNS zone, a correct SPF configuration will appear in the "Suggested SPF Record" section. This section also allows you to perform the following actions:

Conclusion

You are now able to identify any problems related to DKIM or SPF configuration on your domain. Please note that changing your configuration may cause issues when sending emails. Therefore, it is best to modify the SPF configuration only if this was requested by another provider such as Mailchimp or if you encountered an error when sending an email.
