Setup guide
The exact SPF record Google Workspace needs, how to add other senders, and how to publish it.
v=spf1 include:_spf.google.com ~all
Add it as a TXT record at the root of your domain (name @). This allows Google’s mail servers to send for your domain and marks everything else as suspicious. Google recommends ending with ~all.
Add their includes before the ending, in the same record. For example, Google Workspace with Mailchimp and SendGrid:
v=spf1 include:_spf.google.com include:servers.mcsv.net include:sendgrid.net ~all
Keep it to one SPF record and under 10 DNS lookups. The SPF record generator builds it and counts the lookups for you.
Check for an existing SPF record. If there is one, edit it rather than adding a second: see multiple SPF records.
Add or edit the TXT record at @ where your DNS is managed. In GoDaddy, follow adding a TXT record in GoDaddy.
Switch on DKIM too, so DMARC passes even when email is forwarded: set up DKIM in Google Workspace.
Check it with the SPF checker.
