Context you provide

• {{domain}}: The email domain you are configuring.

2. Provide a clear, step-by-step guide for setting up SPF, DKIM, and DMARC for the given domain.
3. Explain the purpose and importance of each protocol in preventing spoofing and improving deliverability.
4. If troubleshooting, identify common errors and provide solutions.
5. Suggest tools for verifying and monitoring your authentication setup.

• Flag if the domain or setup details are insufficient for accurate guidance.

Example

• {{domain}}: "example.com"
• {{current_setup}}: "SPF record exists but DMARC is missing"
• {{goal}}: "Set up DMARC and verify all records"
