Promotions tab

The Promotions tab is one of Gmail's category tabs that separates marketing email from the Primary inbox. Gmail automatically classifies incoming email and routes typically-promotional messages (newsletters, sales emails, transactional confirmations with marketing) to Promotions. Users can override the classification or disable the tabs entirely.

Engagement on Promotions-tab email is lower than Primary-tab email — opens drop 30–50%, clicks drop similarly — but it isn't zero. Engaged subscribers check Promotions intentionally, especially for brands they care about. Promotions classification isn't a deliverability failure; it's a different inbox context.

Optimizing for Primary placement involves reducing the obvious "this is marketing" signals: explicit promotional language, dense link patterns, high image-to-text ratios, common spam-trigger phrasing. Some of this can be controlled at the content layer; some is structural (any email with multiple unsubscribe-list-style headers will skew toward Promotions). Trying too hard to game Primary placement on marketing email tends to backfire; focus on engagement, which improves classification long-term.
