You will learn
Learn which internet browsers and versions are supported when accessing Klaviyo.
If you have trouble accessing Klaviyo, check that you’re using an up-to-date supported browser and that JavaScript is enabled.
Browser support policy
Klaviyo supports versions of the following internet browsers from the past 2 years:
- Chrome
- Edge
- Firefox
- Opera
- Safari
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
- Use extensions that change how your browser displays content or identifies itself to websites (its user agent)
- Have disabled JavaScript in your browser
Keep your browser up to date to get the latest browser features and security updates.
How to check which version of a browser you have
Use the instructions below to check which browser version you have:
If your browser version is 2 years or older, update your browser, then reopen Klaviyo.
If you still see “Your browser is not supported” in an up-to-date supported browser, check that JavaScript is enabled, then open Klaviyo again.
Connection security
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.
