Most operating systems include compatible browsers (e.g., Windows 10 has Edge).
You may be unable to use Klaviyo if you:
- Are on an older version of the above browsers
- Use a browser not listed
- Have extensions that affect how your browser displays content (i.e., ones that modify your user agent)
Please make sure your browser is up to date so that you can get the best possible Klaviyo experience, including all the latest features and security updates.
If you’re experiencing issues accessing the Klaviyo app using one of the browsers listed above, find out which version you have. Below, we link to instructions on how to check which version you’re on:
If the version is 2 years or older, we strongly recommend updating your browser.
Why these browser versions are required
Klaviyo requires that browsers support a security standard called transport layer security (TLS), specifically TLS 1.2. This ensures that a browser uses reasonable security when connecting to the Klaviyo app, hosted pages, or any other content hosted and managed by Klaviyo.
Up-to-date versions of Google Chrome, Mozilla Firefox, Apple Safari, Opera, and Microsoft Edge will support this without any extra steps.
