Rails 8.1.0 (October 22, 2025)¶ ↑

• Add structured events for Action Mailer:

  • action_mailer.delivered

  • action_mailer.processed

  • action_mailer.delivered

  • action_mailer.processed

• Add deliver_all_later to enqueue multiple emails at once.

  user_emails = User.all.map { |user| Notifier.welcome(user) }
  ActionMailer.deliver_all_later(user_emails)
  
  # use a custom queue
  ActionMailer.deliver_all_later(user_emails, queue: :my_queue)
  

  This can greatly reduce the number of round-trips to the queue datastore. For queue adapters that do not implement the enqueue_all method, we fall back to enqueuing email jobs indvidually.
