Better Mailer Previews

Better Mailer Previews is a Ruby on Rails gem that makes it easier to preview ActionMailer email templates.

What you get

• Shows all your previews live on the homepage
• Easily resize individual mailers, for testing responsive layouts
• Forward your previews to an email address (uses the default ActionMailer delivery method for your app).
• Fully compatible with, and can live alongside, native Rails ActionMailer Previews
• Supports namespaced mailers (think User::SignupMailer) as of v1.0.1

Mounting it

# Gemfile
gem "better_mailer_previews"

# config/routes.rb
mount BetterMailerPreviews::Engine, at: "/better_mailer_previews"
