Enabling DKIM for Sendgrid
Note: Irrespective of you using a shared or dedicated IP, SendGrid automatically enables DKIM for all outbound emails to improve email deliverability, and generates 2 CNAME DKIM records for you to publish in your domain’s DNS for your specific DNS hosting service to configure the protocol.
In order to enable DKIM for SendGrid go through the following steps:
Login to your SendGrid account
Go to Settings > Sender Authentication > Authenticate Your Domain by clicking on Get Started
Now choose your DNS Host (GoDaddy, Bluehost, Cloudflare) from the options and click on Next.
Enter the domain name you would like to authenticate and click Next.
You will be able to see 2 DKIM records now (Selector1 – s1 and selector 2 – s2) respectively.
Now you may publish these 2 DNS records for your domain and we’ve completed the DKIM authentication setup process for SendGrid.
You can lookup and validate your published DKIM record using our free DKIM record lookup tool.
