Objective
Are your messages to Gmail users ending up in the Promotional tab? This is likely due to Gmail flagging your message as promotional due to the content of your email. This guide explains some of our recommendations and best practices for avoiding your email showing up in Promotional if it shouldn't be there.
Notice: Please keep in mind that Promotions Tab was created specifically for marketing emails. If you are sending marketing emails, we do not encourage trying to cheat Gmail’s algorithms by trying to have your marketing emails land in the main inbox. Trying to game the system and avoid accurate promotional message filtering can have a negative impact on deliverability overall.

Procedure
Subject, Content, and Structure
Gmail’s algorithms scan the subject, body text, and structural elements of incoming emails to determine their intent. To improve your inbox placement:
-
Review Subject Lines and Copy: Reconsider sales-heavy subject lines or commercial phrasing in your message body. Check out our blog for examples of high-performing subject lines:
Understand Structural Triggers: Gmail uses structural markers—such as the presence of an unsubscribe link or marketing-specific headers—to identify promotional email. When these elements are detected alongside commercial copy, Gmail has high confidence that the Promotions tab is the correct destination.
Ask Subscribers to Move Your Emails: Encourage your recipients to drag your messages from the Promotions tab into their Primary inbox. This trains Gmail's algorithm to deliver your future emails directly to Primary for that user.
Additional tips
Separate Transactional and Marketing Content: Selling in an email is promotional by definition. If you send both transactional and marketing communications, keep them strictly separate so your non-promotional messages aren't miscategorized.
Focus on Quality and Engagement: Create compelling content that encourages recipients to open and click. Avoid overly commercial jargon or aggressive sales language that triggers automated filters.
