Which mail server for the domain should I choose?

Question

gmail

We need mail to send confirmations of something and notifications.
Yandex mail limits the daily sending and takes repeated letters as spam.
Mail does not seem to have a limit, but it is not intended to be used for this purpose. For business only.
Need unlimited.
Or is it better to raise your mail server? And how?
Site on go.

Answer 1

yandex, mail...
You look in the wrong direction at all.
For mailings, mailing services are used, not public / free mail services.
Mailgen, Unisender, Pechkin, etc. - from
our Mailgun, Mandrill, SparkPost, SendGrid - from Western
> Unlimited.
Free unlimited = own server.
But you need to configure it correctly so as not to get into spam.
Well, of course, it depends on the volume, hundreds of thousands per day from your own server - you can’t send it in any way. Yes, and you will get into the limits on servers like Yandex / mail.

Answer 2

Unlimited, this is your own hemorrhoids. Calculate what will be cheaper for you.

Answer 3

your own is better, because it gives you complete freedom of action, but like everything else, there are some nuances
1. install the software, set it up, test it (several days)
2. accept slaps and process them
3. you need a competent admin who can do this
4. costs for iron, although you can take a dedicator, but it's still a cost
