Google Workspace does not require special configuration actions for SPF outside of Authenticate. Please follow these steps to complete configuration for Google Workspace and then return to your automation-guided task list in Authenticate. 

Set up in Google

Use Google's help article to set up DKIM on their side.

Copy out the DKIM key from Google. You'll need to add it on the Sender Detail page for Google Workspace.

Be sure to click 'Start Authenticating' in Google's portal.

Set up in Valimail

1. Make sure you have added Google Workspace as an “Approved Sender” in Authenticate for the domain you are configuring it for. If it's not there, already, use  '+Add Sender'

2. Mark the service Approved. This automatically enables SPF support, so Google will pass on SPF.

3. A DKIM key should be added automatically. If you don't see one yet, try refreshing the page.

4. If you need to add a DKIM key, click 'Add DKIM Key'

5. Enter the values for your DKIM key as provided by Google.

If you've turned on DKIM on Google's side, you should be done and your emails will authenticate reliably.
