Cloudflare adds the three MX records with their priorities when Email Routing is enabled.
Add include:_spf.mx.cloudflare.net to the domain's single SPF record, for example:
v=spf1 include:_spf.mx.cloudflare.net -all107 of 109 Cloudflare Email Routing customers in our sample (98.2%) have this include in their SPF record.
Publish a TXT record at _dmarc.<domain> once SPF and DKIM pass for all mail you send, start with p=none and a reporting address, then move to p=quarantine or p=reject:
v=DMARC1; p=reject; rua=mailto:dmarc-reports@<domain>Official documentation: MX
