Email Meter is the email analytics teams get when Gmail and Microsoft 365 don't tell them enough. It connects to your existing Google Workspace or Outlook accounts and shows how your team actually handles email, without changing the way anyone works.

You can see first response time, average and median response time, SLA compliance, email volume, busiest hours, thread length and how the workload is split across the team. Email Meter also reports on shared mailboxes on both Gmail and Outlook, so you can tell who is carrying the load and whether you are hitting your response time targets. Most inbox analytics tools only do this for individual mailboxes.

Dashboards are easy to read and easy to share, reports can be scheduled, and a BigQuery connector handles email at enterprise scale. Teams use Email Meter to rebalance workload, set and monitor SLAs, speed up customer replies and run weekly reviews based on what really happened.

Email Meter is used by teams at companies like Fujifilm and Avery Dennison. The results are concrete: Payday HCM cut its average response time from 5 hours to 2 hours, Entirety improved by 48 percent and Fujifilm by 30 percent. There is a free plan to start with, and paid plans for bigger teams and enterprise needs.

Best for support, sales and customer success teams on Gmail or Microsoft 365 who want to track response times, SLA compliance and workload, including across shared mailboxes.

React Complex Tree features and specs

  • Customizability
    React Complex Tree offers a high degree of customizability, allowing developers to tailor the tree component to fit their specific needs. This can be especially useful for creating unique UI experiences.
  • Feature-Rich
    The library includes a wide range of features out of the box such as drag-and-drop support, keyboard navigation, and dynamic data loading, which can save development time.
  • Accessibility Support
    React Complex Tree is designed with accessibility in mind, providing support for ARIA attributes and keyboard interactions, which helps ensure that applications are usable by people with disabilities.
  • Performance
    The component is optimized for performance, handling large data sets efficiently without significant slowdowns, which is critical for applications that manage extensive hierarchical structures.
  • Community and Documentation
    The library has a supportive community and well-structured documentation, providing developers with ample resources to troubleshoot and extend its functionality.

Possible disadvantages of React Complex Tree

  • Complexity
    Due to its extensive features and customizability, React Complex Tree can be complex to set up and configure properly, which may lead to a steeper learning curve for new users.
  • Bundle Size
    As a feature-rich component, React Complex Tree can increase your bundle size, which might be a concern for projects where performance and loading time are critical.
  • Third-Party Dependency
    Relying on a third-party library introduces dependencies outside of your control, which may present challenges in terms of long-term maintenance and potential update or deprecation issues.
  • Specific Use Case Tailoring
    While it offers a lot of features, developers may find that very specific use cases require additional effort to customize or extend the component beyond its intended use.

Questions & Answers

As answered by people managing Email Meter and React Complex Tree.

What makes your product unique?

Email Meter's answer

It tracks first response time, SLA compliance, workload and volume automatically, and adds industry benchmarking and email sentiment analysis. Teams get the picture that Gmail and Microsoft 365 do not show natively, without changing how they work.

Email Meter's answer

Choose Email Meter if you want complete team email analytics across both Gmail and Outlook, including shared mailboxes, with response times, SLA compliance, workload and industry benchmarking.
