Summary
The Gmail promotions tab is a specialized inbox category designed to help users manage their promotional and marketing emails. While it serves to organize the user's inbox, its impact on email open rates and the underlying mechanism of pixel loading is a frequent concern for email marketers. The common perception is that placement in the promotions tab can lead to significantly lower engagement. However, the reality is more nuanced, as open rates can be affected by various factors, including the pre-loading of images by Gmail's proxy servers, which can sometimes inflate or deflate reported open rates.
Key findings
- Open rate impact: Emails landing in the Gmail promotions tab often show lower reported open rates compared to those in the primary inbox.
- Pixel loading: The promotions tab appears to have a lower pixel loading rate, meaning the invisible tracking pixels used to measure opens may not always fire, leading to underreported open statistics.
- Deliverability versus engagement: Placement in the promotions tab indicates successful inbox delivery; the issue is more about perceived engagement than actual deliverability to the inbox.
- Metrics divergence: While open rates may drop significantly, other engagement metrics like click rates might not decrease proportionally, suggesting that interested recipients still engage.
Key considerations
- Analyze full funnel: Focus on downstream metrics beyond just open rates, such as clicks and conversions, to get a true picture of campaign performance, especially when emails land in the promotions tab.
- Content optimization: Review email content and sending practices to understand why Gmail categorizes emails as promotional. Our guide on how Gmail decides placement can help.
- Expectation management: Understand that promotional tab placement is normal for marketing emails and does not inherently mean poor performance. Tim Watson of Zettasphere notes that promotional emails are read only slightly less than primary tab emails.
- Pixel accuracy: Be aware of the limitations of open rate tracking due to pixel loading variations, especially when dealing with Gmail's image caching. Our article on Gmail image caching affects accuracy provides more detail.
What email marketers say
Email marketers often express concern over emails landing in the Gmail promotions tab, primarily fearing a negative impact on open rates. While some acknowledge that this placement is a natural categorization by Gmail, others actively seek ways to avoid it. The discussions frequently revolve around whether the lower reported open rates are due to reduced recipient engagement or technical factors like pixel loading. Many marketers now emphasize the importance of looking beyond raw open rates to other engagement metrics to truly assess campaign success.
Key opinions
- Open rate decline: A common observation among marketers is a significant drop in reported open rates when campaigns consistently land in the promotions tab.
- Pixel loading theory: Many marketers suspect that lower reported opens from the promotions tab are due to reduced pixel loading, rather than a complete lack of recipient interest. This can be influenced by how Gmail pre-fetches images.
- Focus on clicks: There's a growing consensus that raw click-through rates (CTR) are a more reliable indicator of engagement when emails are categorized in the promotions tab, as they reflect active user interaction.
- Not a deliverability problem: Marketers frequently acknowledge that landing in the promotions tab is not a sign of poor deliverability, but rather a segmentation of the inbox by Gmail.
Key considerations
- Evaluate true engagement: Shift focus from inflated or deflated open rates to more actionable metrics like clicks, conversions, and revenue, especially if emails are landing in the promotions tab.
- A/B testing: Test different subject lines and preheader texts that might encourage opens even within the promotions tab, as an eye-catching image can make a difference.
- Audience segmentation: Consider if your audience actively checks the promotions tab. For some, it's a dedicated space for deals they want to see.
- Optimize content for tab: Embrace the promotions tab as a legitimate inbox destination. Optimise content, subject lines, and preview text specifically for this tab to maximize open rates from there. You can learn more about image sizes and placement in our guide.
Marketer view
Email marketer from Email Geeks observed a significant drop in open rates, from an average of 70% to consistently around 15%, for a client's newsletter, with emails consistently landing in the Gmail Promotions tab. This dramatic shift highlights the perceived impact of tab placement.
Marketer view
Email marketer from Email Geeks noted that despite the drop in open rates, their IP and domain reputation on Google Postmaster remained high. This suggests that the issue was not with overall sender reputation but specifically with how Gmail categorized the emails.
What the experts say
Deliverability experts generally agree that the Gmail promotions tab is a segmentation feature, not a spam filter. While it can influence how opens are tracked due to image proxying and pre-fetching, it does not necessarily mean emails are going unnoticed. Experts often advise marketers to reconsider the significance of raw open rates in this context and instead focus on deeper engagement metrics. The consensus is that emails in the promotions tab are indeed delivered to the inbox, albeit a specific section of it, and still have the potential for engagement.
Key opinions
- Not a deliverability issue: Experts emphasize that emails in the promotions tab have successfully bypassed spam filters and are delivered to the recipient's inbox, just a categorized one. You can learn more about primary versus promotional tab impact.
- Pixel loading distortion: The variability in pixel loading (or lack thereof) in the promotions tab can distort reported open rates, making them an unreliable metric for actual user engagement. Our page on how tracking pixels affect deliverability has more info.
- Down-funnel metrics: True campaign success is better measured by clicks, conversions, and revenue, as these metrics are less susceptible to inbox rendering quirks. Our guide on how to increase email click through rate details this.
- User expectation: Many users expect promotional content to appear in the promotions tab and actively check it for deals, implying that placement there can be an advantage for relevant content.
Key considerations
- Focus on value: Provide compelling value in your emails, regardless of tab placement, to encourage recipients to open and click.
- Monitor secondary metrics: Pay close attention to down-funnel metrics, like click-through rates and conversions, to accurately gauge campaign effectiveness instead of solely relying on open rates.
- Acknowledge Gmail's role: Understand that Gmail's algorithms categorize emails based on content and sender behavior, and the promotions tab is an intended feature for marketing messages. Our article on Gmail's promotions tab behavior can offer further insight.
- Audience behavior: Recognize that different audiences interact with the promotions tab in varied ways. Some users intentionally visit it for deals and updates, making it a viable space for engagement.
Expert view
Deliverability expert from EmailLabs notes that while open rates may dip when emails are moved to the Promotions tab, down-funnel metrics such as clicks and conversions often remain stable. This suggests that the promotions tab does not necessarily hinder actual engagement.
Expert view
Deliverability expert from Acrelia suggests that the launch of the Gmail Promotions Tab, despite initial fears of significant open rate decreases, has not necessarily had a devastating impact on email marketing. Promotional mail can still perform effectively within its designated tab.
What the documentation says
Technical documentation and research often clarify how email clients, particularly Gmail, handle images and categorize emails, which directly impacts open rate tracking. This includes details on image proxying, pre-fetching, and the criteria used to sort messages into tabs. While documentation may not directly state that the promotions tab 'affects' open rates, it provides the technical context for why measured open rates might vary. It underscores that email opens are inferred from pixel loads, and anything impacting that load can affect the reported metric.
Key findings
- Image proxying: Gmail loads images through its own proxy servers, which can sometimes trigger tracking pixels before a user actually views the email, leading to inaccurate open rates.
- Tracking pixel mechanics: Open rates are typically measured by a 1x1 invisible image pixel. The loading of this pixel sends a signal back to the sender's server.
- Categorization criteria: Gmail uses various algorithms, including sender reputation, content, and user engagement, to determine if an email is promotional and should be tabbed.
- Email clipping: If an email is too large, Gmail might clip it, potentially preventing the tracking pixel at the bottom from loading unless the user clicks to view the full message.
Key considerations
- Understand pixel limitations: Recognize that reported open rates might not perfectly reflect actual engagement due to Gmail's image proxying. Learn more about how email tracking pixels work.
- Content best practices: Adhere to best practices for email content and design to avoid triggering promotional flags unintentionally. Optimize email image sizes and formats.
- Test inbox placement: Utilize inbox placement tools to see where your emails land across different providers, including Gmail's tabs. This can help you understand how to beat average email open rates.
- Monitor spam rates: Keep an eye on your spam rate in Google Postmaster Tools. While the promotions tab is not spam, a high spam rate can indicate deeper deliverability issues. Consult our guide on Google Postmaster Tools V2.
Technical article
Documentation from HubSpot Community explains that not all email opens are tracked for Gmail, particularly when emails are clipped. This occurs because the small invisible image tracking pixel at the bottom of the email may not load until the user clicks to view the full message.
Technical article
Documentation from Influno details that an email tracking pixel is a tiny, almost invisible 1x1 image embedded in emails. When this pixel loads upon opening an email, it sends back information that is used to record an 'open' event.
