Authenticate your domain or die. 💀
Sending pro emails without authentication is technical Russian roulette. 🎰 And right now, Gmail is completely ruthless. 📉
To save your domain reputation and actually hit the inbox, you need these 3 pillars locked down:
📋 1. SPF (The Guest List) ➔ Authorizes your sending IPs. 🔏 2. DKIM (The Wax Seal) ➔ Cryptographically signs your emails. 👮 3. DMARC (The Bouncer) ➔ The orchestrator that rejects spoofers.
Stop letting your emails rot in the spam folder. 🛑
