You may want to know what email clients your recipients are using in order to optimize the design of your template. For example, if most of your recipients are reading your email in Outlook on Windows, your message should not use fonts that are unavailable on Windows.
Here's how to see what the popular email clients are:
- Go to the Reports tab.
- Click on the email campaign you want to inspect.
- The top 5 email clients are shown in the Summary section. For a more detailed view, click Recipients or Charts > Email Clients.
