Depending on the set of Apps you have chosen, SendGrid can alter or add links to emails. This includes unsubscribe links, click tracking, and open tracking. In addition, SendGrid adds email headers that reference SendGrid’s servers so remote servers can verify the authenticity of emails. These links and headers reference the sendgrid.me or sendgrid.com domain.
SendGrid allows companies to customize the domain that appears, a process called Whitelabeling. SendGrid does this using a subdomain for your domain. For example, if your domain is EXAMPLE.COM, you might use EMAIL.EXAMPLE.COM, where EMAIL is your sub-domain.
Your first step is to choose a subdomain. Common examples are EMAIL, MAIL, CONTACT, NEWS, NEWSLETTER, but you can make it anything you like. Now you just need to run the Whitelabel Wizard from your account and the wizard will generate the DNS records you need to add to your DNS entries. Below are links to some hosting and domain name registrars that you might be using.
Our Whitelabel Wizard makes it easier to setup your Whitelabel by walking you through the necessary steps and verifying your settings along the way. You can access the Whitelabel Wizard by navigating to the “Developers” menu and choosing “Whitelabel”
The following records are needed for links, SPF, DomainKeys, and DKIM to work correctly.
|example.com.||TXT||v=spf1 include:sendgrid.net ~all|
If your DNS server does not allow underscores in CNAMES you will have problems adding the smtpapi._domainkey CNAME records. If that is the case please create the following TXT records instead:
SendGrid allows you to have your own dedicated IP address to help build your own reputation. These IPs need to be mapped to real names. SendGrid handles the mapping of an IP to a name, reverse DNS records (RDNS), and expects the mapping of the name to match the IP in the RDNS record. Please use the Whitelabel Wizard or contact support for the IPs and the names needed to be setup. In this case, an IP of 192.168.2.1 has been given the name o1.email.domain.com. SendGrid assigns the mapping of 192.168.2.1 to o1.email.example.com, and the following A record is needed to map o1.email.domain.com to 192.168.2.1:
