Setting up a Google Workspace: SPF, DKIM and DMARC Records
Once you get the Google Workspace set up, you will need to add TXT records to the domain to improve email deliverability and prevent spoofing. Google will send an error message if you do not.
After working with Google support, I got some clarity on the records.
SPF Records
Reference this help article: https://support.google.com/a/answer/33786?hl=en&ref_topic=9061731&sjid=6887155437240596817-NC
Here is an example from websitesmadewithlove.com, which includes MailChimp, a screenshot and then some code after:
Name: websitesmadewithlove.com.
v=spf1 +mx +a +ip4:165.22.233.249 +include:_spf.google.com +include:relay.mailchannels.net ~all
Here is a more basic option for Google Workspace only:
v=spf1 include:_spf.google.com ~all
DKIM
You need to follow this help article: https://support.google.com/a/answer/174124?src=supportwidget0&hl=en&authuser=0#dkim-create-key
You will have to generate the key; always do the smaller character length, 1024, so it doesn’t split. It takes 48 hours to authenticate, don’t forget this crucial step.
DMARC
Here is the Google help article: https://support.google.com/a/answer/2466580?hl=en&ref_topic=9061731&sjid=6887155437240596817-NC
This one is pretty simple but cant be done until DKIM is authenticated.
Ad the TXT record as shown below:
Name: _dmarc.insertyourdomainhere.com.
TTL: 3600
Type: TXT
Record: v=DMARC1; p=none;
