可以使用after_action
请检查以下示例：

class YourMailer < ActionMailer::Base
  after_action :check_email_delivery, only: [:your_action]

  def your_action
    # Your email generation code
  end

  private

  def check_email_delivery
    # Implement your custom logic to check email delivery status here
    # You can use SMTP libraries or services to verify the delivery
    # For example, you can use the `smtp_mail` gem to check delivery status

    # Update your database or perform other actions based on the delivery status
  end
end
