List of e-mail recipients is confusing

[tadeu]

List of e-mail recipients is being configure as ['[email protected]', '[email protected]'] instead of [email protected] [email protected].

Does not seem to be a bug, in the documentation it says to list recipients as:

email_notification:
  recipients: "[email protected] [email protected]"

but it's counterintuitive, something like this is what would be expected:

email_notification:
  recipients:
    - [email protected]
    - [email protected]
