我正在尝试使用 Mailgun 从我的服务器发送一封电子邮件。这是一封非常基本的纯文本电子邮件，但由于某种原因，它最终被归为垃圾邮件。SPF 和 DKIM 通过了。有什么想法吗？我没有任何线索。这将是用于交易电子邮件.. 而不是垃圾邮件/新闻通讯等。

Testing some Mailgun awesomness!
任何线索都会有帮助。我对此没有太多经验。提前致谢。
答案1
虽然 DKIM 和 SPF 有助于将您自己标识为该域的发件人，但垃圾邮件发送者也可以使用它们，因此他们无法保证邮件投递。
不同的目的地对电子邮件信息的不同方面赋予不同的权重，但以下是主要要点，大致按重要性从高到低排列：
- 电子邮件的内容。Gmail 似乎比其他邮件更依赖这一点。
- 投递尝试率（尤其是与 IP 的移动平均值相比）
- 发送服务器/IP 的信誉
- DNS 机制（SPF、DKIM、PTR 记录、A 记录、MX 记录等）
- 发送域的声誉
- 邮件格式，包括邮件头异常
我要做的第一件事是测试真实的您要发送的电子邮件的内容，而不是“这是一个测试”。如果它不起作用，请向发送您邮件的人（在本例中是 mailgun）投诉。
