Email authentication is the process that allows you to mask BenchmarkONE as your relay point in sent emails and replace it with your own domain. This does not affect any email sent outside of BenchmarkONE, but it will improve your deliverability when sending emails from your BenchmarkONE account.

Email authentication can be accomplished with the addition of a few DNS records on your sending domain. You will need access to your domain host’s DNS panel to complete these changes. If you are not able, it's likely your web developer or whoever set up your email account can complete these for you.

Additional information:

1. SPF

If your domain already has an SPF record:

Find the TXT record that begins with “v=spf1”.

  1. Edit this record.

  2. Before or after any “include:” statement, add this —

  3. Be sure to save your changes.

If your domain does not have an SPF record:

Can’t find a record that begins with “v=spf1”? You will need to add a brand new record.

Add a new TXT record –

  • Type: TXT

  • Host / Name: @

  • Value: v=spf1 ~all


Add a new CNAME record –

  • Type: CNAME

  • Host / Name: f1._domainkey

  • Value:

3. Custom Return-Path

Add a new CNAME record –

  • Type: CNAME

  • Host / Name: bounce

  • Value:

4. Custom Link Wrapping

Add a new CNAME record –

  • Type: CNAME

  • Host / Name: You will choose the host name. It is common to use something like “link” so when BenchmarkONE wraps your links for tracking they will appear as ""

  • Value:

💡 NOTE: Once you have added this record to your DNS, you must provide the host name to our support team so we can complete the setup from our side.

Confirming Authentication is Complete

You will need to let our team know the changes are complete by reaching out to and including your email sending domain(s). If you are implementing custom link wrapping, you must also provide us the host name entered for that CNAME record.

Since changes to your DNS can take some time to propagate across the internet, we may not be able to confirm your changes right away. A best practice is to allow roughly 24 hours for the records to propagate and the BenchmarkONE team to verify them. During this window of time you will not want to send emails out of BenchmarkONE to ensure you don't unintentionally receive bad delivery rates while the changes are still propagating.

Once we are able to verify the updates are correct you have the green light to resume sending!

Help Articles for Popular Domain Hosts

Below we have included help articles for popular domain hosting services to assist with updating/adding records within their DNS portal. If you do not see your domain service listed, you can typically Google your provider’s name and “manage DNS” to find the help you need.

Please note that any questions specific to your domain host’s portal should be sent to your provider. The BenchmarkONE support team can help with common questions, but cannot offer specific support within your DNS tool.
