Why Email Authentication Matters in 2024+
1. Avoid the Spam Folder
Major inbox providers (Google, Yahoo, Microsoft) now strictly quarantine or reject unauthenticated marketing and transactional emails.
2. Prevent Phishing & Domain Spoofing
Without SPF and DMARC, anyone can forge emails claiming to come from your @yourdomain.com address.
3. Improve Sender Reputation
Consistent DKIM signing and strict DMARC policies build positive reputation with mail servers worldwide.
