Get your own email server to send it through. Follow all the rules to make this server believable, the content believable and then just MAYBE will you be able to reach all those people with your message. However if the message actually is spam someone will mark it as so and most people won't receive it anyway.
当您发送电子邮件时，您必须监控垃圾邮件阻止列表以查看您的服务器 IP 是否出现在其中。如果是这样，您将必须联系他们并申请将您的服务器从阻止列表中清除。
发送 1000 万封电子邮件的美好时光已经一去不复返了。只有大公司才能做到不被封锁。
I would recommend using your own mail server on your own server rather than the gmail server.
But this won't prevent your emails being flagged as spam. It all depends on the recipient's email settings.
You will also have to edit your emails to ensure they do not contain spam related topics and methods because spam filters which check content will mark it as spam.
As you send your emails, you will have to monitor spam block lists to see if your server IP appears on them. If it does, you will have to contact them and apply for your server to be cleared from the block lists.
The good old days of send 10 Million emails is gone. Only the big companies can do it without being blocked.
you can use gmail smtp for max 90 users at a time else your gmail will be banned by google. So, to play safe you may send 50 emails per hour but that's taking forever for 500k emails list. I recommend you to use your own server which allowing you to send 500 emails per hour. Use phplist, they look like a professional autoresponder if you know how to mod and customize it like i did on my site http://phplistmod.com please take a look at it.
I don't think there is any way to sent 5000,000 mails at a time bc its like you are spamming all think or just want to sent newsletter as you say.
all mail providers are have a certain limit to sent mails at a time you need special account with your email provider to access this kind or facility as you mention above you are using gmail account to send mail
i think you need to to go with the third parties solutions for this.
I seem to have succeeded by making sure the rDNS record was correct and making some DNS changes including signing with DKIM (requires configuration of the mail server and DNS record).

这称为“tarpitting”，旨在防止人们发送大量电子邮件。

获取您自己的电子邮件服务器来发送它。遵循所有规则，使该服务器可信，内容可信，然后也许您就能将您的消息传达给所有这些人。然而，如果该邮件实际上是垃圾邮件，有人会将其标记为垃圾邮件，并且大多数人无论如何都不会收到它。

我建议在您自己的服务器上使用您自己的邮件服务器，而不是 gmail 服务器。
但这并不能阻止您的电子邮件被标记为垃圾邮件。这完全取决于收件人的电子邮件设置。
您还必须编辑您的电子邮件，以确保它们不包含垃圾邮件相关主题和方法，因为检查内容的垃圾邮件过滤器会将其标记为垃圾邮件。

您一次最多可以为 90 个用户使用 gmail smtp，否则您的 gmail 将被 google 禁止。因此，为了安全起见，您可以每小时发送 50 封电子邮件，但这对于 50 万封电子邮件列表来说需要很长时间。我建议您使用自己的服务器，每小时可以发送 500 封电子邮件。使用 phplist，如果您知道如何像我在我的网站上那样修改和自定义它，它们看起来就像一个专业的自动回复器 http://phplistmod.com 请看一下。

我认为没有任何方法可以一次发送 5000,000 封邮件，因为这就像您在发送垃圾邮件一样，或者只是想像您所说的那样发送新闻通讯。
所有邮件提供商对一次发送的邮件都有一定的限制
您需要电子邮件提供商的特殊帐户才能访问此类或设施
正如您上面提到的，您正在使用 Gmail 帐户发送邮件，
我认为您需要使用第三方解决方案。

通过确保 rDNS 记录已成功，我似乎已成功更正并进行一些 DNS 更改，包括使用 DKIM 签名（需要配置邮件服务器和 DNS 记录）。
