Understanding Inbox Placement

Inbox placement goes beyond basic email deliverability. While deliverability simply confirms that your email was accepted by the recipient's server, inbox placement determines whether it lands in their primary inbox or gets filtered into the spam or promotions folder. This distinction is critical as better inbox placement leads to higher engagement rates, improved scalability of specific campaigns and segmentation strategies, and ultimately, more revenue.

As we reach the final quarter of this year, it’s paramount to focus on mastering trends and strategies that enhance inbox placement, ensuring emails reach their intended audience effectively, as well as helping you leverage other channels in your marketing strategy.

Growing importance for Marketing teams

Inbox placement has traditionally been a primary concern for sales teams, especially those focused on cold outreach where ensuring emails land in the inbox is critical for connecting with potential leads. 

However, inbox placement should be a priority for all marketers—not just those in sales. With engagement-driven algorithms and increasingly sophisticated spam filters, the ability to ensure your marketing emails reach the inbox is essential for driving the success of any email campaign. 

Whether you're nurturing leads, promoting products, or delivering valuable content, if your emails don’t land where they’re meant to, your entire strategy can fall flat. Every email has the same challenge, regardless of your department: getting noticed, getting read, and prompting action—and that starts with strong inbox placement.

With that being said, let’s move on to the top trends that are impacting marketing teams and how you can boost your inbox placement success.

9 key Inbox Placement trends

1. AI-driven personalization and optimization

Surprise surprise, AI is at the forefront of revolutionizing email marketing, offering tools that allow for hyper-personalized email campaigns. AI can analyze past campaigns, predict what content will resonate based on a global analysis of top-performing emails, as well as suggest optimal send times and subject lines. The result? Emails that engage recipients, and therefore reduce your chances of landing in the spam folder.

But AI-driven personalization is not just important to the content creation side of things but is also key in driving primary inbox placement. One trend we’ve seen impact this the most has been predictive tools, like those in Klaviyo, that can even recommend the best time to send emails based on past behavior, ensuring your emails land when users are most likely to engage.

Pro Tip: Explore the AI features in your email marketing software. While the goal of some of these tools may not specifically be geared towards inbox placement, utilizing tools that prioritize high quality content can help optimize email engagement.

2. New metrics to measure inbox placement

Last month, we received yet another update on Google’s evolving spam filters, affecting the deliverability of emails with images (including open rate tracking pixels) sales teams and marketers can no longer rely on open rate as an indicator of Inbox placement, and therefore need to pivot toward engagement metrics such as response rates and sender reputation, to assess campaign success.

Your sender reputation plays a vital role in email deliverability – affecting inbox placement. It’s built on factors like engagement, spam complaints, and bounce rates. The stronger your sender reputation, the more likely your emails will reach the inbox. 

Another essential factor is email authentication. Implementing protocols like DKIM, SPF, and DMARC helps build trust with internet service providers (ESPs) and ensures your emails aren’t flagged as suspicious.

Actionable Tip: Regularly monitor your sender reputation and ensure your emails are authenticated with protocols like DKIM and SPF to boost inbox placement.

3. List-centric email marketing

As we mentioned above, marketers must rethink how they track and engage users. Existing regulations like GDPR and Apple’s Mail Privacy Protection have already forced marketers to reshape their target contact lists in order to stay compliant, but staying compliant doesn’t guarantee your emails will still reach your subscribers. 

Building a strong sender reputation, ergo hitting the primary inbox of your users, also now depends on clean opt-in practices and regular email list cleaning. By focusing on users who opt-in and actively interact with your content, you reduce the risk of being marked as spam.

While consent-driven email lists are crucial, it’s equally important to regularly clean your lists to remove any users who may harm your sender's reputation. Even with opt-in subscribers, some recipients may mark your emails as spam, or their addresses may become inactive or invalid over time. Failing to remove these problematic addresses can result in increased bounce rates, spam complaints, and lower engagement, all of which negatively impact your inbox placement.

Pro Tip: Conduct regular list hygiene by identifying and removing unengaged users and invalid emails to maintain a healthy sender reputation and improve your inbox placement. Only include "safe" emails in your campaigns—those that are verified and show a positive engagement history.

4. Leveraging first-party data and segmentation

As third-party cookies phase out, first-party data is gaining importance. First-party data allows marketers to create more accurate audience segments, resulting in highly targeted emails that recipients are more likely to engage with.

Targeted emails, driven by first-party data, are key to better inbox placement. Segmentation based on user behavior, such as purchase history or website interactions, ensures that your emails are relevant and engaging, improving both engagement rates and inbox placement.

Pro Tip: Use insights from surveys, purchase behavior, and website activity to build segmented email lists that cater directly to user interests.

5. Hyper-segmentation and frequency

As you very well know, generic, one-size-fits-all email campaigns are a thing of the past–we’ve all tested segmentation based on industries and other demographics, but it’s time to double down on your efforts. Hyper-segmentation not only means creating more personalized content based also on location, purchase history, behavior, and such, creating smaller, more defined groups of users.

Equally important as the content itself is email frequency. Sending hyper-segmented emails on a regular and consistent schedule can significantly improve inbox placement by fostering higher engagement rates. When you tailor content to specific segments of your audience, the relevance increases, leading to more opens, clicks, and interactions—all positive signals to email service providers (ESPs). 

However, sending mass email campaigns infrequently or inconsistently can trigger ESP spam filters, as irregular email patterns and low engagement are often associated with spammy behavior. Consistency and relevance are key to maintaining a strong sender reputation and ensuring your emails consistently reach the inbox.

Pro-tip: If you’re just starting to send out email campaigns, you should apply email warm-up and throttling for maximum email deliverability.

6. Interactive emails 

Interactive emails—featuring elements like polls, quizzes, or carousels—are becoming more popular as marketers look for ways to increase engagement. Dursiksya reports that interactive emails can boost click-through rates by up to 73%, a stat that highlights their potential impact.

Higher engagement signals to ESPs show that your emails are valuable and deserve to land in the inbox. However, it’s essential to ensure that interactive elements don’t slow down your email or trigger spam filters.

Pro Tip: Make sure the interactive elements don’t slow down your email or trigger spam filters. It’s also a good idea to avoid adding interactive elements in your very first communication with a new subscriber.

7. Mobile-first email design

With over 60% of emails being opened on mobile devices, designing with a mobile-first mindset is essential. Emails that aren’t optimized for mobile can result in low engagement and high bounce rates, both of which hurt your sender reputation and inbox placement.

By focusing on mobile-friendly design, including larger touch targets and easily scannable content, you can improve user experience and engagement.

Pro Tip: Also consider a responsive design, email content layout, and best practices that are suitable for smart watches for increased engagement with your users.

8. Email accessibility

As email marketing continues to evolve, accessibility is becoming more important. Ensuring your emails are accessible to all users, including those with reading difficulties, can significantly improve engagement rates.

Accessible emails, featuring alt text, readable fonts, and proper contrast, signal to ESPs that your emails are designed for broad usability, which in turn improves inbox placement.

Tip: Follow Web Content Accessibility Guidelines (WCAG) to make your emails accessible to all users, improving overall engagement.

9. Cross-departmental accountability

Inbox placement is not just the responsibility of one team—it’s a shared priority across the entire organization. Every email sent from your domain, whether it’s from marketing, sales, or customer success, contributes to your sender reputation. If one department is sending emails that result in high bounce rates, low engagement, or frequent spam complaints, it can negatively affect inbox placement for everyone. This means that all teams must be aligned in their email practices to ensure emails are being delivered, engaged with, and trusted by email service providers (ESPs).

To avoid any unintended damage to your sender reputation, it’s critical to collaborate across departments. Ensure that marketing, sales, customer success, and any other team sending emails are using clean email lists, crafting relevant content, and adhering to best practices. Consistency across all outbound email communications will improve inbox placement and maintain a healthy sender reputation.

Pro Tip: Implement an inbox placement tool that allows all team members to connect their mailboxes and review email performance metrics. This will enable your entire team to track and optimize behaviors that could impact overall inbox placement, ensuring a unified approach to improving deliverability across the board.
