E-mail authentication is the process that allows you to mask Dyn as your relay point in all of your emails and replace it with your own domain. This does not affect any email sent outside of BenchmarkONE; but, it will drastically improve your deliverability when sending from your BenchmarkONE account. E-mail authentication can lead to a better sending reputation and more consistent inbox delivery.

This can be accomplished with the addition of a few new DNS records, you need to have access (and permission!) to make some DNS changes on your sending domain.

Contact BenchmarkONE Support or your Consultant for the correct records for your domain. You will need to add three TXT records:

1) An SPF record (or edit your current SPF to include our email vendor).

2) A domain key record with a selector of "dyn."

3) A domain key policy record.

Below is example text of what the changes will look like:

NOTE: Do NOT add these records. These are only examples. Contact support@benchmarkone.com to receive the records needed for your domain.


HOST: yourdomain.com
DATA: v=spf1 include:spf.protection.outlook.com include:spf.dynect.net -all


HOST: dyn._domainkey.yourdomain.com
DATA: k=rsa; t=y; p=large_amount_of_numbers_and_letters_here


HOST: _domainkey.yourdomain.com
DATA: t=y; o=~;

After adding these records to your domain, they can take some time to propagate across the internet. A best practice is to give yourself roughly 24 hours before sending any emails once you have made the DNS changes. This is only to ensure you don't unintentionally receive bad delivery rates while the changes are propagating.

If you have any questions, or if you'd like to begin this process, contact support@benchmarkone.com for more information.
