Outgoing e-mail connector / trigger

[kazagz]

What would you like to see!

While there is possibility to notify users via e-mail, I would like to see possibility to trigger e-mail based on alert payload. In our shop we're getting alert from many different sources and some of source specify contact persons / e-mails in alerts. What is required is to have the same functionality "Outgoing webhooks" have, but in this case they would trigger e-mail notifications.

Example

Alert payload:

{
    "message": "Something bad is happening",
    "mail": [
        "foo@example.com",
        "bar@example.com"
    ]
}

This would trigger "Outgoing e-mail" using Jinja2 templates - one for subject, message and recipients:

# Adding all templates here, but in reality these would
# be 3 inputs similar to how they are for existing e-mail notifications

# --- Title (subject) template ---
{{ payload.message }}

# --- Message template ---
Hello,
you should check this: {{ payload.message }}

# --- Recipients template, should accept comma separated list ---
{{ payload.mail | join(",") }}

The result would be mail sent to "foo@example.com,bar@example.com".
