How to configure SPF and DMARC?

SPF and DMARC are TXT records in DNS that protect your domain from spoofing and improve email deliverability. Generate the records above and add them in your domain registrar's DNS panel.

Start with SPF using ~all (softfail) and DMARC with p=none. After analyzing DMARC reports, switch to -all and p=reject.
