GMail 將基本電子郵件發送到垃圾郵件文件夾。SPF DKIM 好嗎？

我正在嘗試使用 Mailgun 從我的伺服器發送電子郵件。這是一個非常基本的純文字電子郵件，但由於某種原因它最終成為垃圾郵件。SPF 和 DKIM 通行證。有任何想法嗎？我沒有任何線索。這將用於交易電子郵件.. 不是垃圾郵件/通訊等。

Testing some Mailgun awesomness!

任何線索都會有所幫助。我在這方面沒有太多經驗。提前致謝。

雖然 DKIM 和 SPF 在將您自己辨識為該域的發件人方面很有用，但垃圾郵件發送者也可以使用它們，因此它們不能保證送達。

不同的目的地對電子郵件消息的不同方面的權重不同，但這裡是要點，大致從最重要到最不重要排列：

• **電子郵件的內容。**Gmail 似乎比其他人更依賴於此。
• 傳遞嘗試率（尤其是與 IP 的移動平均值相比）
• 發送伺服器/IP 的信譽
• DNS 機制（SPF、DKIM、PTR 記錄、A 記錄、MX 記錄等）
• 發送域的信譽
• 消息格式，包括標頭異常

我要做的第一件事是測試您打算發送的電子郵件的*真實內容，而不是“這是一個測試”。*如果它不起作用，請向發送郵件的人投訴（在這種情況下為 mailgun）。
