How to setup dkim signature?

Question

Email Marketing

In general, the problem is of this nature. I needed a domain mail to send a mailing list. I went to the quark with this question. And everything seems to be in order, everything works, BUT! Emails sent to gmail.com go to spam. And the problem is only with gmail. On the mail tester I get a score of 8.7. How to fix the first line for which I got -0.1 points? I know about the new domain, maybe it somehow affected the way gmeil treats me?

Answer 1

Good evening!
Do not look at minus 0.1, it is extinguished by the next line.
Most likely, either there were clicks on spam on Google, or the domain was not heated enough.

Answer 2

The second and third lines say that the signature is valid.

Answer 3

It may also be worth connecting Gmail Postmaster Tools in order to have a more detailed idea of ​​the deliverability of letters to this particular mailer.
