How does Gmail's Top Promotions feature work and what factors influence its display?

Summary

Gmail's Top Promotions feature is a dynamic display within the Promotions tab of the Gmail mobile app (and soon desktop), designed to highlight key promotional emails for users. It aims to improve user experience by surfacing relevant deals and updates, but its exact mechanics and influencing factors are not fully transparent, leading to much discussion among email marketers and deliverability experts.

What email marketers say

Email marketers often approach Gmail's Promotions tab with mixed feelings. Some view it as a necessary evil or even a 'spam trap,' while others recognize it as a valuable opportunity for engagement. The introduction of Top Promotions has further spurred discussions about how to optimize campaigns to gain this elevated visibility, with many focusing on the role of subscriber engagement and content optimization.

Marketer view

A marketer from Email Geeks notes that they recently observed the Top Promotions feature and found that while many displayed emails were from brands with high engagement, some were from senders they had forgotten about. This indicates that engagement is likely a significant factor, but it may not be the sole determinant. The presence of emails from less-engaged sources suggests that other algorithms or broad sender reputation metrics might also play a role in initial visibility.

Marketer view

A marketer from Email Geeks questioned whether the Top Promotions feature was simply a new way for Gmail to present ads. This reflects an initial confusion among some users and marketers about the nature of this new functionality, distinguishing it from traditional advertisements. The distinction between organic promotional emails and paid advertisements is crucial for understanding its impact on email marketing strategies.

What the experts say

Deliverability experts largely agree that Gmail's Top Promotions feature is an extension of its existing inbox categorization, driven primarily by user behavior and a sender's overall reputation. They often highlight that this tab is an important part of the inbox experience, not a de facto spam folder, and that senders should focus on foundational deliverability practices and engaging content to improve their chances of visibility.

Expert view

An expert from Email Geeks notes that FreshInbox previously published content about Gmail's testing of subject line images with promotional cards. They indicate that there aren't many specific details available on how Gmail determines which messages receive top billing, suggesting the process is still somewhat opaque to the public. This highlights the ongoing challenge for senders in deciphering Gmail's complex algorithms for promotional email placement.

Expert view

An expert from Email Geeks suggests that Gmail's Top Promotions feature likely starts by using a global view of engagement. They predict that over time, it will probably shift towards an individual user's view once sufficient data is gathered, indicating a phased rollout approach for the algorithm. This evolution would make the feature even more personalized and responsive to individual subscriber preferences.

What the documentation says

Google's official documentation provides insights into how the Promotions tab works and how senders can optimize their emails for it. The focus is heavily on email annotations, which allow for a richer, more engaging experience directly within the Promotions tab, making emails more appealing and discoverable to users who are actively browsing for deals and content.

Technical article

Documentation from Google for Developers indicates that email annotations are designed to enhance messages within the Promotions tab with features like images, deals, and expiration dates.
