You own the pipeline.
Not the mail server.

Here’s what the email terms mean for your team, and what to ask the person managing your setup.

Email essentials

SPF: Sender Policy Framework; The list of services allowed to send using your domain. Ask your DNS team to review it when you add or remove a sending platform.; Included in your public DNS check.
DKIM: DomainKeys Identified Mail; A signature attached to your email that receivers can verify. Your sending platform provides the DNS records needed to set it up.; Not measured by public DNS alone.
DMARC: Domain-based Message Authentication, Reporting and Conformance; Connects authentication to the address recipients see in the From field. Your policy tells receivers how to handle messages that fail those checks.; Included in your public DNS check.
MX: Mail Exchanger; The records that point incoming email to your mail provider. Have your email team review them if replies or incoming messages aren’t arriving.; Included in your public DNS check.
Reputation: Sender reputation; How mailbox providers assess your sending, including complaints and sending patterns. A clean DNS report cannot tell you whether your reputation is healthy.; Not measured by public DNS alone.
Placement: Inbox placement; Where a message lands after it is accepted. Your sending platform may say “delivered” even when the message ends up in spam.; Not measured by public DNS alone.
