发送电子邮件广播 [英] Sending Email Broadcasts

问题描述

我正在开发一种应用程序，允许管理员定期发送注册用户（选择加入）广播电子邮件，或根据各种其他条件。在任何情况下，我很好奇，我是否应该单独发送一封电子邮件给每个收件人或bcc所有这些邮件。目前，电子邮件列表大约有1500个收件人，但它应该一直扩展到至少25k，没有问题。

I'm working on an application that will allow management to send registered users (opt-in) broadcast emails at regular intervals, or based on various other criteria. In any case, I'm curious as to whether I should send a separate email to each recipient or bcc all of them on a single message. Currently the email list would be about 1500 recipients, but it should scale all the way up to at least 25k without problems.

想法？我进入一个范围，我需要担心放在垃圾邮件列表上？

Thoughts? Am I getting into a range that I need to worry about being put on spam lists?

推荐答案

是的，我有垃圾邮件列出该大小的邮件列表问题，管理非营利组织的电子邮件列表。

Yes, I've had spam list problem with mailing lists of that size, managing email lists for non-profits.

想要采取额外的预防措施：确保您的电子邮件已 SPF 记录，写一个脚本批量发送电子邮件，随着时间的推移逐步发展。一次一个发送给他们，而不是bcc，因为直邮有更好的机会。使其非常容易取消订阅。在发送的消息中包含人们订阅的电子邮件 - 通常人们将电子邮件转发到另一个帐户，然后尝试取消订阅该帐户并感到沮丧。

One wants to take extra precautions: make sure your email has SPF records, write a script to send the emails in batches, paced out over time. Definitely send them one one at a time, not as bcc, as direct mail has a better chance of arriving. Make it very easy to unsubscribe. Include people's subscribed email in the message sent -- often people have email forwarded to another account and then try to unsubscribe that account and get frustrated.

即使如此，如果您必须在某些时候更改您的IP，不要惊讶。

Even so, don't be surprised if you have to change your IP at some point.
