Do authentication protocols make emails “safer” for users?

Yes. Authentication protocols help make emails safer by verifying sender identity and message integrity. This helps recipients and their mailbox providers distinguish legitimate mail from spoofing attempts.

Without authentication, anyone can claim to send from any domain. With authentication, spoofed messages fail verification, enabling better filtering of phishing and spam.

Authentication does not make email content safe; malicious senders can authenticate too. But it prevents impersonation of legitimate domains, protecting brands and helping recipients trust verified senders.
