DKIM is an important authentication protocol that allows domain owners to sign their outgoing emails with a unique key that is matched against a public key that exists in their DNS during verification. In order to set up DKIM for Sparkpost, follow these steps:
Set Up Your Domain on Sparkpost
Open your Sparkpost application and add a sending domain, if you haven’t already done so during registration
If you have registered your domain on Sparkpost, you can find all your existing domains on the Domains page
Click on the domain to set up DKIM verification
On the Domain Details page scroll down to DNS verification and copy the DKIM record value and hostname
Login to your DNS management console and publish the record. It can take up to 24-48 hours for the record to be effective after publishing.
Verify Your Domain on Sparkpost
Click on the verify button at the bottom of the page after you are done publishing the DKIM record in the DNS.
You will receive a confirmation from Sparkpost that your domain has been successfully verified.
Finally, look up and validate your DKIM record using our free DKIM record lookup tool.
