Email service providers (like Google and Microsoft) filter incoming mail aggressively to protect user inboxes. If your technical records are missing or misconfigured, you get marked as spam automatically.
1. The Mechanics of Deliverability
Spam filters look for sender reputation, blacklists, engagement rates, and correct technical setup. Writing better subject lines will not help if your server is blocked by ISPs.
2. DNS Core Records
Configure dedicated SPF, DKIM, and DMARC text records in your domain settings to verify your authorization to send emails from that address.
3. The Warm-Up Protocol
Never send thousands of emails from a new address immediately. Increase daily sending volumes slowly over 3-4 weeks to establish domain authority.
