There’s no software to install, so your Gmail or Outlook speed won’t be affected at all. EmailAnalytics works entirely and exclusively through the back-end (via the Gmail and Outlook API). In other words, we get our data directly from Gmail and Outlook’s servers, not yours. And no, you don’t need to train employees how to use EmailAnalytics  It’s a monitoring tool that is designed to help you visualize email activity. Neither you nor your team members need to do anything different; just continue emailing the way you normally do!
