Monitor the email authentication records that affect deliverability.
Email authentication explained
SPF (Sender Policy Framework)
SPF specifies which mail servers are authorized to send email for your domain.
DKIM (DomainKeys Identified Mail)
DKIM adds a digital signature to verify emails haven't been modified in transit.

DMARC tells receivers what to do when SPF or DKIM checks fail.
