DMARC

Your domain Policy (p) Subdomain policy (sp) Aggregate report address (rua) Percentage (pct) Alignment

Host/name: _dmarc

SPF

Tick every service that sends email as your domain.

Extra IPv4 addresses (comma separated) Ending

Host/name: @ (root)
Type: TXT
Value:

Only one SPF record per domain is allowed: edit your existing one rather than adding a second. Some providers (Mailchimp, HubSpot) authenticate with DKIM and don't need an SPF include. Lookup counts shown are approximate (a provider's own nested includes add more). Verify with the checker.
