How do I know if emails have been flagged or are in spam?

Question

gmail

Good afternoon!
Context: through gmail smpt mail is sent from the domain, say [email protected]
Usually, about 100 emails are sent per day.
I verified the domain and connected postmaster gmail.
but here's the trouble for 2 years, zero statistics.

What could be wrong?
You need to understand when emails are automatically detected as spam.
(it is known that this is not often but it happens)

Thank you in advance!

Answer 1

Postmaster statistics are built not by emails sent by a Google user, but by domain emails sent to Google mailboxes. At the same time, Google has additional requirements for the number of letters at which statistics begin to be displayed. What matters is not how many emails you send, but how many emails you send to GMail recipients. Also, only letters authorized by DKIM are usually included in the statistics, make sure that it is in your letters.

Answer 2

If anti-spam will inform senders (that is, potential spammers) that the letters are in spam, this anti-spam is worthless.

Answer 3

Only indirectly. Try to create new mailboxes in Zhmail, Yandex and other popular mailers, and then send letters to them.

Answer 4

No way. As the host, I can do whatever I want with the letter. Generally. And the sending side has no means of detecting this.
