No. They are not there at all.

Spam filters can respond to certain words if they are present in the header or body of the email. I try to avoid using the following words (they were found by experience, and I do not guarantee that this is the correct list)

You need to set up dkim, spf, dmarc. The user must also activate the subscription. And when he signs, display a message: "If you did not find our letter, check your spam folder. If it is there, check the "not spam" box next to the letter."

There is no data in the log about messages that were not sent.

Everything is sent from one customer. But another customer with a Cyrillic sending server on Punycode sends only activation letters. But then mailing letters are not sent. What do you advise?
