Did you know? While each web browser has a mobile version for tablets and smartphones, it is designed for devices that rely on touch input and have smaller screens and slower processors. It's best to open Constant Contact in a web browser on your desktop or laptop computer, or download the Constant Contact mobile app for your iOS or Android device.

Unsupported web browsers

If you're using an unsupported browser (Vivaldi, Brave, PaleMoon, SeaMonkey, Qwant, etc.), you'll see a special message indicating that it isn't supported. We won't prevent you from using the browser, but you may run into issues because we can't guarantee 100% compatibility with Constant Contact.

To help our customers have the best possible experience with Constant Contact, we also prevent very old versions of supported browsers from accessing our service. If you log in to Constant Contact with one of these browser versions, you’ll see a special message asking you to update or use another browser. We currently block:

• Google Chrome - Version 110 and lower
• Mozilla Firefox - Version 127 and lower
• Microsoft Edge - Version 110 and lower
• Microsoft Internet Explorer - All versions (11 and lower)
• Android OS - Version 4 and lower
• Apple Safari - Version 16.3 and lower
• Apple iOS - Version 16.3 and lower
• Opera - Version 96 and lower
