Fix an `ActionView::Template::Error: undefined method 'verification_key' for nil` error in the welcome_user mailer when a user signs up without an email address. Caused by the fact that we now render mail templates regardless of whether the user has an email address, and then skip sending the email only after the mail template is rendered.
Helpers
This directory contains helper functions used by views. Helpers are used for simple common functions, such as linking to users or formatting timestamps.
Helper functions are globals. If you see an unnamespaced function in a view, and it's not a Rails function, then it's probably a helper defined here.
All helper functions defined in this directory are globally available to all views. They're not limited to single views. For example, the functions in posts_helper.rb are available to all views, not just to app/views/posts.
The use of helper functions should be minimized. Partials or components are preferred for more complex widgets, or for things used in only one or two places. Helper functions should be limited to very simple things used in nearly all views.
