Some of the email workflows, like updating a user's email, require the back-end api-server to send out emails. While developing, you can use a tool to catch these emails locally instead of having to use an email provider and send an actual email. MailHog is one such email testing tool for developers that will catch the emails your local freeCodeCamp instance is sending.
Download the latest MailHog version from [MailHog's official repository](https://github.com/mailhog/MailHog/releases). Click on the link for your Windows version (32 or 64 bit) and the .exe file will be downloaded to your computer.
Once it finishes downloading, click on the file. You might get a Windows firewall notification where you will have to allow access to MailHog. Once you do, a standard Windows command line prompt will open with MailHog already running.
Once you have installed MailHog and started it running, you need to open your MailHog inbox in your browser. Open a new tab or window and navigate to [http://localhost:8025](http://localhost:8025).
