Gmail uses sophisticated algorithms to sort emails:
Factors Affecting Tab Placement:
Content type and language used
Sending patterns and volume
User engagement history
Commercial content indicators
Common Triggers for Promotions Tab:
Marketing language and sales phrases
Bulk sending patterns
Commercial imagery and formatting
Previous promotional sending history
Best Practices:
Focus on personalized, valuable content
Maintain clean mailing lists
Monitor engagement metrics
Use appropriate authentication (SPF, DKIM, DMARC)
Consider whether Promotions tab placement aligns with your email goals
Note: While some senders try to "game" the system to reach the Primary tab, the Promotions tab is a legitimate inbox location designed to help users organize their email, not a spam folder.
