Browser requirements and clearing the cache

WordFly is a web-based application that works in most web browsers. There are a few browser-related settings to have enabled and important notes to review.


Compatible browsers

  • Mozilla Firefox
  • Safari
  • Microsoft Edge
  • Google Chrome 


Browser settings

  • JavaScript should be enabled in your browser, so you can view errors, alerts, and preview screens.
  • Adobe Flash is currently required for editing the Subscribe, Unsubscribe, and Forward pages in the Account > Custom Pages section. A new way to create these pages will be released at the end of 2020.


Important notes

  • You can only work in a single browser tab when working in WordFly. Multiple tabs are not supported.
  • We highly recommend removing all plug-ins from your browser. Plug-ins can add unwanted code to your email and page designs.
