How to get the signature "Sender confirmed and verified" in Yandex Mail?

Question

Yandex

Hello. On my WordPress site, I turned on sending emails to the user after registration with login data (sent by the Woocommerce plugin) - in the inbox of such letters there is a yellow icon and the signature "The sender is confirmed. However, the letter came from the domain *address and signature of the hoster*, which does not correspond to the reverse address". When sending newsletters with the Mailpoet plugin, it's even worse - a red icon and a signature that the letter is most likely forged. However, nothing got into my spam while I was testing it.
Tell me how to get the green "Verified Sender" badge, what manipulations with the tambourine do you need to do to do this? DNS for the domain is registered from Cloudflare, I did not create corporate mail on Yandex.

1) You make mail for your domain in Yandex.360 at a trial rate (for free, it is not necessary to delegate the domain)
2) You create a mailbox, be sure to enter it once via Yandex mail.
3) Install the SMTP plugin and send emails with mailbox credentials.
