As for free/cheap to send emails from the site?

As for free/cheap to send mail from the website with different notifications?

I saw a bunch of similar topics, but the responses all write that in your mail server no one sends through the gmail server or Yandex, too much is not sent, but how for example are forums out there subscribe to new notifications of replies to the topic, etc, the result is quite a large number of emails per day.
Using paid services will be too expensive, 0.1-0.2 per 1 letter.

through your mail server no one sends

some nonsense
Any hosting email service... you just have to send an email with mail

there are services with free limits (Yes, the same Amazon)
and inexpensive
and with your server.

but there are nuances

most of them with their server, why not send

100-200 fit perfectly in Gmail API / SMTP
and Yandex is also nearby
