Building Your SPF Record

Step 1: Start with version

Always begin with: v=spf1

Step 2: Add your sending sources

Add an include: for each service that sends email for you.

Step 3: Add specific IPs (if needed)

If you have your own mail server: ip4:YOUR.IP.ADDRESS

Step 4: End with policy

Choose your ending:

• -all – Hardfail (reject unauthorized) - Recommended
• ~all – Softfail (mark as suspicious) - Safer for testing

Important Rules

• ⚠️ Maximum 10 DNS lookups – Each include: counts as 1+ lookups
• ⚠️ Only ONE SPF record per domain – Multiple records cause failures
• ⚠️ Maximum 255 characters per string – Long records may need splitting

After Creating Your Record

1. Add it as a TXT record in your DNS
2. Wait for propagation (up to 48 hours)
3. Verify with SPF Checker
