## What does the Mailgun integration do?

Our Mailgun integration enables the automation of email communications. Use the Mailgun API within Rewst workflows to send emails, trigger workflows when receiving emails, and more.

## Set up the Mailgun integration

### Set up steps in Mailgun

1. Log in to Mailgun.
2. Navigate to **Sending > Domain Settings > Sending Keys**.
3. Choose your appropriate domain from the drop-down selector, if you use multiple domains.
4. Click **Add sending key**.
5. Enter a name for the key.
6. Copy the **Sending API key** value displayed in the dialog.  You won't be able to view the key again after you close it. Store this key somewhere secure. You'll need it for further steps in Rewst.

### Set up steps in Rewst

1. Navigate to **Marketplace > Integrations** in the left side menu of your Rewst platform.
