How to Update SPF, DKIM, and ARC Records for a Google Workspace Email Address

Updating SPF, DKIM, and ARC records for a Google Workspace email address involves several steps. Here’s how you can do it:

1. Update SPF Record

SPF (Sender Policy Framework) helps prevent email spoofing. To update or set up an SPF record for Google Workspace:

  1. Access DNS Settings: Log in to your domain host’s website and go to the DNS settings page.
  2. Locate the SPF Record: Look for a TXT record with “v=spf1” in its value. If it exists, that’s your SPF record.
  3. Modify or Create SPF Record:
    • If an SPF record exists, add to the record without creating another SPF record.
    • If no SPF record exists, create a new TXT record with the value: v=spf1 ~all.

2. Update DKIM Record

DKIM (DomainKeys Identified Mail) adds a digital signature to emails. To set up or update DKIM for Google Workspace:

  1. Generate the DKIM Key:
    • Go to your Google Admin console.
    • Navigate to Apps > Google Workspace > Gmail.
    • Click on ‘Authenticate email’.
    • Select your domain and generate the DKIM key.
  2. Add the DKIM Key to DNS Records:
    • Copy the DKIM key generated by Google Workspace.
    • Go to your domain’s DNS settings.
    • Create a new TXT record.
    • Enter the DNS Host name (provided by Google Workspace) in the ‘Name’ field.
    • Paste the DKIM key in the ‘Value’ field.

3. Update ARC Record

ARC (Authenticated Received Chain) is relatively new and is used for email authentication. It’s not as commonly set up as SPF and DKIM, and Google Workspace doesn’t specifically provide ARC records to be added. ARC is typically used by intermediaries (like mailing lists or forwarding services) and not directly set up in DNS like SPF or DKIM.

For SPF and DKIM, after updating the records, it’s important to:

  • Save Changes: Save the new records in your DNS settings.
  • Wait for Propagation: DNS changes can take up to 48 hours to propagate.
  • Verify Setup: Use Google Workspace’s tools or third-party tools to verify that SPF and DKIM are correctly set up.

For ARC, if you’re using a service that recommends setting up an ARC record, they should provide specific instructions on how to do so. Otherwise, focusing on SPF and DKIM should suffice for most Google Workspace email authentication needs.
