电子邮件未通过deliver_later发送给所有用户

Question

我正在迭代一组订户ID以向每个订阅者发送电子邮件，但由于某种原因，并非所有订阅者都收到该电子邮件。

这是调用模型方法的控制器：

class Admin::EmailDigestsController < ApplicationController
    def send_digest
        article_ids = params[:article_ids]
        subject = params[:subject]
        EmailDigest.send_email_digest(article_ids, subject)

        redirect_to email_digests_path
    end
end

这是email_digest.rb：

class EmailDigest < ActiveRecord::Base

    def self.send_email_digest(article_ids, subject)
        subscribers = EmailDigest.where.not(status: "Inactive").ids

        subscribers.each do |subscriber|
          DigestMailer.weekly_digest(subscriber, article_ids, subject).deliver_later
        end
    end

end

这是digest_mailer.rb：

class DigestMailer < ActionMailer::Base
   default from: "secret@secret.com"

    def weekly_digest(subscriber, article_ids, subject)

        @subscriber = EmailDigest.find_by_id(subscriber)
        @subject = subject
        articles_arr = []
        article_ids.each do |f|
          articles_arr << Article.find_by_id(f)
        end
        @articles = articles_arr

         mail(to: @subscriber.email,
         subject: subject)
    end
end

我也设置了sidekiq并且它足以发送至少一封电子邮件，但也许错误处理方式有问题。

感谢您的帮助
