When you send an email, providers want to confirm:“Is this sender legitimate?”Authentication proves your emails are truly coming from your domain.
SPF: Defines which servers are allowed to send emails for your domain
DKIM: Verifies the email hasn’t been altered
DMARC: Tells providers how to handle suspicious emails
Without authentication:
Emails are more likely to go to spam
Some messages may be blocked entirely
With proper setup:
Your emails appear more trustworthy
Inbox placement improves
