Here are the main reasons why your emails might be going to junk folders:
Primary Causes:
1. Lack of Email Authentication
You’re sending emails without proper technical setup like SPF, DKIM, and DMARC records. Without these, email servers see you as an anonymous sender and treat you like a potential phisher, blocking your emails on sight.
2. Poor Sender Reputation
Your sender reputation works like a credit score. Email providers score you based on:
- High bounce rates
- Spam complaints from recipients
- Low engagement rates
- Sudden volume spikes in sending
- Blacklist appearances
3. Content-Related Issues
- Spammy subject lines or content: Using trigger words like “best price,” “big bucks,” “cash bonus,” “extra income”
- Improper HTML formatting or heavy use of images
