Amazon SES：如何向所有用户发送HTML邮件

Question

I want to send all users (<200) on the rails application. The mail server is Amazon SES. If the lists were over 50, we have to divide email transactions.

So I coded like below:

class NewsMailer < ApplicationMailer
  def all_notify(news)
    @news = news
    @users = User.where(is_news: true)

    @users.each do |user|
      mail(
        subject: @news.title,
        to: user.email,
      )
    end
  end
end

Although email has been sent, but html was collapsed like this.

When I try to send to one user. It doesn't occur the problem. But when using each causes the problem...

Do you have any ideas?

Answer 1

  @users.each do |user|
    NewsMailer.all_notify(@news, user).deliver
  end

I could do it by writing each on the controller.
