# Configure Mailgun

[Mailgun](https://www.mailgun.com/) is required in order to send email notifications from Taskforce.sh to your users. Most likely the free account will be enough for your needs. However Mailgun requires a valid credit card in order to create the account to avoid spammers to exploit their service.

You will need to pick the **Private API key** and use it in the Taskforce.sh configuration tool**.**
