Is there a reliable and inexpensive SMTP service?

Question

Mail server

In an existing project, there is a need to send email notifications to users. There are few users (about 1.5), each of them receives several letters per day on various system events, in addition to this, there are several mailing lists a couple of times a month. In total, it turns out about 150k letters per month.
For a long time, we used https://pdd.yandex.ru/ for sending notifications and https://www.mandrill.com/ for mailing lists. But some time ago, PDD began to ban, mark messages as spam and, accordingly, stopped sending them to users.
From what I see to use it is:

• , it turns out about $ 200 per month
  
• , about 12000 rubles
  

But in any of these cases, the cost of mail is commensurate with the cost of hosting. Actually, the question is: are there more affordable, but at the same time reliable alternatives?
