Heads up: If you had previously set up DKIM and SPF records for your SMTP sending, you will need to migrate to the newer improved CNAME version below.

Getting started

Adding CNAME records to your DNS validates your sending email address from Groove, improving your email deliverability and white labeling your emails. 

This is done by making your email deliverability compliant with the DMARC authentication standard, adding an additional layer of security against hackers and spoofing of your domain.

This feature is only available to Mailboxes making use of Groove's SMTP servers. Mailboxes connected via Gmail OAuth need to have DMARC setup within the Gmail admin section.

To get started, locate the DNS control panel for your domain or contact your DNS hosting company.

Step 1. Finding Your CNAME Records

First, you need to go to the mailbox you would like to add the CNAME records for:

  • Click the cog in the left hand navigation in your Groove inbox to go to settings
  • Navigate to the Conversations section
  • This should have you on the Mailbox menu option, where you need to select which mailbox you would like to grab the CNAME records of
  • In the mailbox configuration page, you will see the 3 CNAME records you will need to add to your DNS


Step 2. Adding CNAME records

Next, you'll need to create the CNAME records within your DNS provider's administration panel and configure it to point to your Groove host. Each of the CNAME records will need to be added individually.

Here is an example of adding a CNAME record to a DNS provider:


Step 3. Checking Your New DNS Settings

We've made it simple to test and make sure the CNAME records are configured correctly right from the mailbox. Just under the CNAME records is a "Test DNS" button that will show you if the records are set up correctly or not. For each CNAME record there are 3 possible states:

  • Invalid: The records are set up incorrectly or haven't been setup
  • Valid: You're good to go!


A task will run once per day at midnight Pacific Time to check that your DNS is configured properly. If there is an issue detected, your white labeling will be disabled.
