Read sender-domain health
Interpret SPF, DKIM and DMARC signals.
What is checked
Domain health inspects public DNS authentication signals such as SPF, DKIM and DMARC for a domain you enter. It explains configured, missing or uncertain findings without making a deliverability prediction.
DNS changes can take time to become visible. Recheck after the new records have propagated.
Use the findings
Treat domain health as a configuration aid. A healthy signal does not guarantee an individual message will be delivered.
