这是你的字符集问题，在sendblaster中撰写电子邮件时选择正确的字符集，即“windows-1252”
This is the issue of your charset, select the correct charset when composing email in sendblaster, that is "windows-1252"
Google 故意限制在单个会话中和不同时间范围内可以发送的电子邮件数量。当您收到 500 封邮件时，我怀疑您已经在使用他们的一款高级产品 - 例如 Google Apps for Enterprise。
不过，请注意电子邮件流量是在整个域中测量的，并且您可能会限制公司其他用户的电子邮件或共享 Google Apps 帐户。
要批量发送数千封电子邮件，您将需要一个专门的邮件列表管理器 - 在 Google 中搜索大量产品。您还必须更改您的 DNS 记录，以证明您没有发送垃圾邮件。
要发送无限数量的消息，您将需要访问专门的营销服务。
Google deliberately limits the number of emails that can be sent in a single session and over various timeframes. As you achieved 500 mails I suspect that you are already using one of their premium products - such as Google Apps for Enterprise.
Still, beware that email traffic is measured across the whole domain and that you may be restricting email for other users at your company, or sharing the Google Apps account.
To send batches of thousands of emails you will need a dedicated mailing list manager - search Google for lots of products. You will also have to make changes to your DNS records to prove that you are not sending spam.
To send unlimited numbers of messages, you will need access to a dedicated marketing service.
根据我的经验，最好的免费邮件解决方案是spark post，它免费为您提供10万封电子邮件，但请记住，当您使用免费的第3方服务时，您正在使用共享服务器，因此如果其他免费用户发送垃圾邮件从共享 IP 来看，您的邮件也可能会被发送到垃圾邮件，因此我建议您实施自己的 smtp 服务器或采用付费计划。更新
经过一番研究，sparkpost 似乎不再提供此免费套餐。但没有好的选择。我能找到的最接近的是 Mailgun，最好的情况是如果您从 AWS EC2 服务器发送在这种情况下，您每月可以获得 62000 封免费邮件 SES。
PS：这些可能会发生变化，并且仅在更新时有效。否决这篇文章无助于改变公司政策。
The Best Free mailing solution according to my experience is spark post which gives you 100k emails for free, But do remember when you're using free 3rd party services, you're using shared servers, therefore if other free users send spam from the shared ip, your mail will probably be sent to spam as well, hence I recommend Implementing your own smtp server or going for a paid plan.UPDATE
After some research it seems sparkpost no longer offer this free package. But there are no good alternatives. Closest I can find is Mailgun, And best case scenario would be if you send from an AWS EC2 server in which case you get 62000 free mail per month SES.
