What are the Russian services for sending mail (similar to mailgun)?

Question

Web development

We use mailgun to send mail.
Due to the current situation, there are problems with payment plus the risk of blocking.
What are the alternatives in Russia?
It is highly desirable that SMTP is supported (or there is integration with django), so as not to reinvent the wheel.
