Why is gmail throwing an email as spam?

Question

gmail

Hello! I use The Bat to send emails. Mail and Yandex accept the letter as normal, but Google throws it in spam. And the letter is the usual "Hi, how are you?". I am using SMTP server. What could be the problem?

Google is quite demanding on mail servers, recently it requires not only SPF, correct hostname, TLS, but also DKIM. So right away without diagnosing your letter - it's impossible to understand the reason. You need to look at the service headers of the letter and analyze, look for possible reasons for such behavior.
