Email Infrastructure
Building Reliable Email Infrastructure for Small Teams
A practical checklist for SPF, DKIM, and DMARC checks when setting up Google Workspace.
When a small team moves its communications to Google Workspace, the biggest surprise is usually deliverability.
Core checks to run first
- Verify domain ownership and brand records.
- Create SPF record with only one hard include.
- Add DKIM keys and publish the selector.
- Enable DMARC with a reporting-only policy before enforcing.
You can use simple scripts to verify all of these in one run.
dig +short TXT yourdomain.com | sed 's/^/SPF: /'
Why this matters
Most failed deliveries are caused by a weak DNS chain, not the sending app.
A clean mail infrastructure creates trust with receiving servers and lowers the chance of fallback spam behavior.
