Sending SMTP requests or another option?

Question

PHP

Previously, I always used Yandex, cut permission and tokens for mail programs to it, and sent it via SendMailSmtpClass.php . But now, even after about 30 pieces of test letters, while setting up - emails have already stopped being sent. Some empty letter from the demon arrived in the mail with which I am sending. That's all) As I understand it, I received a BAN for the mailing list.

What kind of mail do you use to send letters from 100 per day, or maybe even this is the last century and what kind of service has already been invented? Or tell me how to remove the limit in Yad?

Answer 1

Of course, it’s good to have your own, but a competent postmaster is also needed for it.
Write to Yandex support - explain that you are not a spammer, but simply tested your service.
Write what volume of letters you plan - 100 letters per day will fit into their limit. But if your mailing list is spammy, then of course it will not work :)

Answer 2

You just need to raise your own mail on the hosting and already use it for sending. Well, for the lazy, there are notifications via telegrams, which you can send to yourself without restrictions.

Answer 3

What mail do you use to send letters from 100 per day
