Please note some DNS hosts will automatically add your top-level domain to the end of DNS records you create, which can turn a CNAME for “” into “”.

i.e. On Sendgrd states however in your domain settings you would put 'abc123'.

Once these records are updated

7. Tick 'I've added these records' and select Verify.

This is now complete. 

If you face an error with the verification failing please review the entries in your domain and ensure to remove your domain incase your DNShost will automatically adds your top-level domain to the end of DNS records you create. For example “” into “”. So you only need to add in the component prior to your email domain. 

Once you have this all set up you can review your system email activity and manage any suppressions (Bounces/Blocks)
