In order to prevent your emails from being rejected or flagged, we highly recommend configuring DKIM on your domain. The protocol validates your emails and prevents unauthorized sources from sending emails on your behalf.
To get started, Mailjet will walk you through the steps needed to create your domain’s DKIM records. Once that's done, you'll be all set.
Creating DKIM record for Mailjet
Log in to your Mailjet account
Navigate to Account > Domain
Click on ‘Manage’ for the domain you want to authenticate, and view the DKIM record values.
Then click on “Set up domain authentication”
Publish this record in your DNS records section for your respective domain.
Wait for 24-48 hours to allow your DNS to process the changes
