Is it worth it to raise your mail server?

Question

Mail server

I have a website and it has a private messaging module. Now everything works on Yandex pdd. Those. if the user registers, he receives a notification .. Or changes the password, etc.
But I don't have notifications, ie. let's say informing the user that he received 2 messages. And now I'm thinking about how to be ... Should I raise my mail server (to be honest, I don't really rummage about this) or be content with Yandex. I like Yandex, but I think that it may stop sending emails after some limit, or it will simply consider it to be spam =(
Or maybe there is some other solution? Tell me, pliz)

Answer 1

Yandex limits somewhere around 200 emails per day per account. I don't know, maybe there are separate limits for special letters of the "notification" type.
Bulk notifications are services like aws ses, elastic mail, and so on.
Amazon gives 2k letters per day for free, elastic - 5k (without attachments, of course).
Plus, such services usually work successfully with unsubscribes and abuses, and on your mail server you will have to do it yourself. So I am for third-party services.
