Authenticate your sending domain
Inbox placement starts with authentication — here's how to add SPF, DKIM, and DMARC records for your sending domain.
1
In Emails, open Sending domains — unauthenticated domains send from a shared pool with lower deliverability.
2
Copy the DNS records into your registrar — the values are unique per domain, so copy them exactly.
3
Click Verify records — once all three pass, campaigns from this domain sign with your DKIM key. Great for deliverability!
