+## My emails are landing in the spam folder
+
+Emails landing in spam folders is a common issue. Here are key steps to improve deliverability:
+
+1. **Configure proper domain setup**:
+   * Use a dedicated subdomain for sending emails (e.g., mail.yourdomain.com)
+   * Ensure [reverse DNS (PTR) records](https://www.cloudflare.com/learning/dns/dns-records/dns-ptr-record/) are properly configured
+   * Warm up your sending domain gradually
+
+2. **Implement authentication protocols**:
+   * Set up [SPF records](https://www.cloudflare.com/learning/dns/dns-records/dns-spf-record/) to specify authorized sending servers
+   * Enable [DKIM signing](https://www.cloudflare.com/learning/dns/dns-records/dns-dkim-record/) to verify email authenticity
+   * Configure [DMARC policies](https://www.cloudflare.com/learning/dns/dns-records/dns-dmarc-record/) to prevent spoofing
+
+3. **Follow deliverability best practices**:
+   * Include clear unsubscribe mechanisms in all marketing communications
+   * Personalize content appropriately
+   * Avoid excessive promotional language and spam triggers
+   * Maintain consistent HTML formatting and styling
+   * Only include links to verified domains
+   * Keep a regular sending schedule
+   * Clean your email lists regularly
+   * Use double opt-in for new subscribers
+
+4. **Monitor and optimize**:
+   * Track key metrics like delivery rates, opens, and bounces
+   * Monitor spam complaint rates
+   * Review email authentication reports
+   * Test emails across different clients and devices
+   * Adjust sending practices based on performance data
