使用 MailMessage 类发送邮件 - BCC 和 CC 计数的限制?

发布于 2024-12-02 13:25:50 字数 224 浏览 0 评论 0原文

我有一个客户列表(1,000,000 个电子邮件地址),我想使用 MailMessage calss 向他们发送一封特定的电子邮件(所有这些电子邮件都是相同的)。
对于垃圾邮件发送者来说,使用此类或关于此问题的全局规则的 Ensemble 电子邮件是否有任何限制?
密件抄送和抄送数量是否有限制?
我可以发送一封包含一百万个密件抄送地址的电子邮件吗?

提前致谢

is there any limitation(s) about Ensemble Emails using this class or global rules about this issue for spammers?
also is there any limitation about bcc and cc count ?
can i send one email with one million bcc addresses?

thanks in advance

你的方法大错特错了:

  • 不要用相同的非定制电子邮件来打扰这 1,000,000 个客户,当然不是所有人都对相同的服务或产品感兴趣(顺便说一句,我怀疑他们真的都是你的客户,如果你有这样的想法)许多客户(您有 IT 部门和知道答案的人员);
  • 除极少数情况外,一般情况下不应使用密件抄送;
  • 如果您在密件抄送或抄送字段中放入 1.000.000 个电子邮件地址,它可能会在 SMTP 服务器中爆炸,即使不是,也需要很长时间才能发送和传递,并且您将拥有比真实电子邮件内容更多的元数据。
  • 只是不要这样做,如果您想做智能营销或忍者/病毒营销,请选择按业务或其他因素(位置、需求...)聚合的客户子集,并通过真正感兴趣的真实报价联系较小的子集对于那些。

you are deeply wrong in your approach:

  • do not bother this 1.000.000 customers with same not customized emails, surely not all of them are interested in the same service or product (btw I doubt they are really all your customers, if you have so many customers you had an IT department and people who knew the answer);
  • bcc is not to be used in general except rare cases;
  • if you put 1.000.000 email addresses in the bcc or cc field, it will probably explode in the SMTP server and even if not it will take ages to send and deliver and you will have more metadata than the real email content.
  • just do not do it, if you want to do smart marketing or ninja/viral marketing select a subset of those customers aggregating by business or by other factors (location, needs...) and contact the smaller subset with a real offer interesting only for those.

不知道投票否决。

但是邮件中的 ids 数量的限制通常是由服务器端的电子邮件服务器管理员来限制的。如果您有可能一次性发送所有内容,请将其分解为多个块。

同样,如果您使用经过身份验证的方式发送电子邮件(提供 pass 和 unames),那么您的电子邮件服务器不会将您视为垃圾邮件发送者,因此您可以按照自己的意愿发送电子邮件。

顺便说一句,请注意,一次发送十亿个电子邮件 ID 对您的服务器来说是一个巨大的痛苦,除非它是像谷歌这样的服务器群:)

No idea bout downvote.

But the restrictions on No. of ids in a mail is usually restricted by the Email Server's admins at server side. If your having probs sending all at ones, just break it down to chunks.

Again, if your using an authenticated way to send an email (supplying pass and unames), then your email server wont treat you as spammer so you can send the emails as your wish.

Btw, please note that billion email ids at 1 shot is a huge pain for your server unless its a server farms like google has :)

一百万封电子邮件?使用持续联系或 mailchimp 或其他第三方服务(rackspace 现在提供)。

即使您可以创建并发送它,您最终也会被列入黑名单或被发送到很高比例的预期收件人的垃圾邮件文件夹。

One million emails? Use constant contact or mailchimp or other 3rd party service (rackspace now offers it to).

Even if you could create and send it, you'll end up blacklisted or destined for the spam folder of a very high percentage of intended recipients.
