- SPF, DKIM and DMARC
- The three records that stop people sending email pretending to be you, and help your real email avoid the spam folder. Google, Microsoft and Yahoo now require them from anyone sending email in bulk, and filter more heavily when they're missing.
- Email provider
- Where your email is delivered, such as Google Workspace or Microsoft 365.
- Website and HTTPS
- Whether your site loads securely, sends visitors to the secure version, and sits behind Cloudflare.
- DNS hosting and DNSSEC
- Who runs your domain's DNS, and whether its answers are signed so they can't be faked.
