Woocommerce not sending mail, how to cure?

Question

PHP

Hi all!
I noticed that woocommerce does not send emails. You don’t send any letters about a new order or a notification for the customer ...
The most incomprehensible thing for me is that they work successfully from other forms (located on other pages and not connected with woocommerce in any way)! So everything is ok with the server.
It means that woocommerce messes up, but I have no idea how to fix it ...
Some time ago everything worked (a month or two ago) ... Tell me where to dig, what and how to edit, so that everything would work ...
Thank you.

Postal services, Google Mail ban letters (or throw them in spam), try testing on Yandex
