+=========================
+Mail tracking for Mailgun
+=========================
+
+This module integrates mail_tracking events with Mailgun webhooks.
+
+Mailgun (https://www.mailgun.com/) is a service that provides an e-mail
+sending infrastructure through an SMTP server or via API. You can also
+query that API for seeing statistics of your sent e-mails, or provide
+hooks that processes the status changes in real time, which is the
+function used here.
+
+Configuration
+=============
+
+You must configure Mailgun webhooks in order to receive mail events:
+
+1. Got a Mailgun account and validate your sending domain.
+2. Go to Webhook tab and configure the below URL for each event:
+
+.. code:: html
+
+   https://<your_domain>/mail/tracking/all/<your_database>
+
+Replace '<your_domain>' with your Odoo install domain name
+and '<your_database>' with your database name.
+
+In order to validate Mailgun webhooks you have to save Mailgun api_key in
+a system parameter named 'mailgun.apikey'. You can find Mailgun api_key in your
+validated sending domain.
+
+Usage
+=====
+
+In your mail tracking status screens (explained on module *mail_tracking*), you will
+see a more accurate information, like the 'Received' or 'Bounced' status, which are
+not usually detected by normal SMTP servers.
