How to Authenticate a Sending Domain?

To improve email deliverability and protect your domain from spoofing and phishing attacks, it is essential to authenticate your sending domain. Here are the common authentication methods:
SPF (Sender Policy Framework): Defines which IP addresses are allowed to send emails on behalf of your domain.
DKIM (DomainKeys Identified Mail): Adds a digital signature to your emails to verify they haven’t been altered.
DMARC (Domain-based Message Authentication, Reporting, & Conformance): Provides instructions on how to handle emails that fail SPF or DKIM checks.
