- View: Also called a "template", a file that contains markup (like HTML) and optionally additional instructions on how to generate snippets of HTML, such as text interpolation, loops, conditionals, includes, and so on.
- View engine: Also called a "template library" or "templater", ie. a library that implements view functionality, and potentially also a custom language for specifying it (like Pug does).
- HTML templater: A template library that's designed specifically for generating HTML. It understands document structure and thus can provide useful advanced tools like mixins, as well as more secure output escaping (since it can determine the right escaping approach from the context in which a value is used), but it also means that the templater is not useful for anything other than HTML.
- String-based templater: A template library that implements templating logic, but that has no understanding of the content it is generating - it simply concatenates together strings, potenti

Your application is growing, and you are starting to have a complex mailing system: notification emails, retention emails, misc user emails, admin emails, etc...
It's time to clean up your mailers !
You may already have a single mailer, responsible of every emails, like this one:
- Your class can be no longer than 100 lines of code.
- Your methods can be no longer than five lines of code.
- You can pass no more than four parameters and you can’t just make it one big hash.
- When a call comes into your Rails controller, you can only instantiate one object to do whatever it is that needs to be done. And your view can only know about one instance variable.
You can break these rules if you can talk your pair into agreeing with you.
