Brand domain SPF and DKIM configuration

Our branding system sends emails with your brand email address as sender email address to your customers. For our branding system to do so, our SPF-record needs to be added to your brand's email address if there's an active SPF-record in your domain's DNS settings. We also support DKIM, but this is optional and depends on DKIM being active for your brand's sending email address.

To setup our SPF-record and DKIM for your brand's sending email address, follow the instructions below.

SPF-record

1

Add our SPF entry to your domain's SPF-record. The SPF entry is:

include:spf.mydomainprovider.com

2

Use an SPF tool to check if our SPF-record is active for your domain, we frequently use Kitterman for troubleshooting SPF- issues

3

Your domain is now ready to use as sending domain for your Realtime Register branding email address

DKIM

1

Add the below CNAME record to your domain's DNS settings (sendingdomain.com needs to be replaced with your sending domain)

mydomainprovider._domainkey.sendingdomain.com CNAME dkim.mydomainprovider.com
	

2

Check if the CNAME record is active using a dig command

% dig cname mydomainprovider._domainkey.realtimeregister.com  


; <<>> DiG 9.10.6 <<>> cname mydomainprovider._domainkey.realtimeregister.com

Contact support and ask them to activate DKIM for your account. Make sure to inform our support department whether or not the CNAME record has already been created

Once support confirms DKIM is active for your account, you're all set and DKIM is active for the sending domain for your branding email address.
