What is the difference between deliver_now and deliver_later?

deliver_now sends the email immediately in the current process, which can slow down web requests. deliver_later pushes the email to a background queue for processing, which is the recommended approach for better performance.

How do I send emails asynchronously in Rails?

Use the .deliver_later method on your mailer action. This enqueues the email as a background job using Active Job, preventing your application from blocking while waiting for the mail server.

How do I handle multiple recipients in Action Mailer?

The 'to', 'cc', and 'bcc' fields in the mail method can accept either a single email string or an array of email strings for multiple recipients.

Can I preview emails during development without sending them?

Yes, Action Mailer includes a Preview feature. By creating a preview class in test/mailers/previews, you can view the rendered HTML and text versions of your emails in your browser at localhost:3000/rails/mailers.
