What is it?
Deliverability depends on valid mail routing, authentication, sender reputation, message content, and recipient policy.
Why is it important?
Missing MX, SPF, or DMARC records can cause messages to be rejected, quarantined, or routed to spam.
How do you improve it?
Publish valid MX, SPF, DKIM, and DMARC records, monitor reputation, and test real messages with representative recipients.
