Preview emails sent from ActionMailer in the browser.

Mailbin writes emails to tmp/mailbin for easy access and testing.

Add Mailbin to your Gemfile:

bundle add "mailbin"

Configure Rails to send emails to Mailbin:

# config/environments/development.rb
config.action_mailer.delivery_method = :mailbin
config.action_mailer.perform_deliveries = true

Add the routes to view emails with MailBin:

Rails.application.routes.draw do
  mount Mailbin::Engine => :mailbin if Rails.env.development?
end

Open http://localhost:3000/mailbin to view your emails in development.

Mailbin stores emails in tmp/mailbin by default. To change this, you can set the storage_location config.

# config/initializers/mailbin.rb
Mailbin.storage_location = ENV["MAILBIN_STORAGE_LOCATION"] || Rails.root.join("tmp", "mailbin-#{Rails.env}")

If you're using Mailbin outside of development, you can override Mailbin::ApplicationController to add authentication.

class Mailbin::ApplicationController < ActionController::Base
  # Add authentication here
end
