deliver_later!

Enqueues the email to be delivered through Active Job. When the job runs it will send the email using deliver_now!. That means that the message will be sent bypassing checking perform_deliveries and raise_delivery_errors, so use with caution.

Notifier.welcome(User.first).deliver_later!
Notifier.welcome(User.first).deliver_later!(wait: 1.hour)
Notifier.welcome(User.first).deliver_later!(wait_until: 10.hours.from_now)
Notifier.welcome(User.first).deliver_later!(priority: 10)

Options:

• :wait - Enqueue the email to be delivered with a delay

• :wait_until - Enqueue the email to be delivered at (after) a specific date / time

• :queue - Enqueue the email on the specified queue

• :priority - Enqueues the email with the specified priority

By default, the email will be enqueued using ActionMailer::DeliveryJob. Each ActionMailer::Base class can specify the job to use by setting the class variable delivery_job.

class AccountRegistrationMailer < ApplicationMailer
  self.delivery_job = RegistrationDeliveryJob
