If your emails are landing in spam instead of the inbox, you are losing opens, clicks, and customers. This guide explains the real reasons emails go to spam and the exact steps to improve email deliverability.

Why Emails Go to Spam

Spam filters look at your domain reputation, email authentication, content quality, engagement, and sending history. Even legitimate emails can land in spam if these signals are weak.

1. Authenticate Your Domain

  • Add SPF record
  • Enable DKIM
  • Configure DMARC
  • Verify your sending domain

2. Warm Up New Domains

Never send thousands of emails from a brand-new domain. Start with small volumes and increase gradually.
