IMHO, sending email is an action, part of the business logic, and not a view.
Sending email is not an output as well as inserting a record in a database or LDAP server are not outputs.

It doesn't matter that *maybe*, today, or tomorrow, or the next week somebody will access a POP3 server with an email client and will see that email message, as well as it doesn't matter if after a certain time somebody will read that record from the database or LDAP server with an appropriate client.

The views are usually very good to use the same data structure and generate an output in different formats, like csv/xls/xlsx... but very rarely we also need to generate other formats with the fields of an email message (To, Cc, Subject, body, attachments...) so it is also not very helpful to send email using a view.
