Notifier is the layer that provides a way to comunicate with the users, could be a mail service, or a instant messenger service like telegram, jabber, etc...
At this moment only mailgun service it's implemented. 

In order to configure mailgun service, firstly you need a Mailgun account. Register your account here: https://mailgun.com/signup

Once you have your new account you need to configure the notifier transport.
Edit the `instance/config.py` file and add or edit this config:

NOTIFIER_MAILGUN = {
    "transport": "Mailgun",
    "api-key": "key-XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX",
    "host": "https://api.mailgun.net/v3/sandboxceXXXXXXXXXXXXXXX.mailgun.org/messages",
    "from": "from@email.com" 
}

NOTIFIER_DEFAULT = 'NOTIFIER_MAILGUN'

Firstly define your new data structe at models.py, alembic will check this file

then sure your database it's to date
```
alembic upgrade head
``` 
and then add a new revision with a descriptive message
```
alembic revision -m "descriptive message" --autogenerate
```
