This gem makes it possible to send mails asynchronously using Resque by simply rewriting `SomeMailer.some_mail(ar_resource, 1234).deliver` to `SomeMailer.async_deliver.some_mail(ar_resource, 1234)`. Using ActiveRecord objects as arguments to mailers is still possible. This is achieved by storing the class name and the record id as arguments in the Resque queue which will be transformed back to records by the mailer job and passed along to the mailer.

ActionGmailer, oauth/gmail delivery method

Enhances the ActionMailer Previews introduced in 4.1 by automatically creating ActionMailer Previews at runtime in development mode. See automatic previews of your ActionMailer emails, with no extra effort or mock data. Install the action_mailer_auto_previews gem into your :development group, and it'll 'just work' with sensible defaults. Each ActionMailer email object that has .deliver or .deliver_later called will automatically launch your default browser right to a ActionMailer Preview page with the real data passed to that email. Flexible options allow you to alter this behavior as well. Warning: Since this is dynamically creating Ruby classes/methods, you will want to make sure your web-server is single threaded. For example, if you're using Puma, be sure to set the `workers` configuration parameter to 1.
