Hello!
Interested in what services for email marketing exist? + sms + push notifications
To be able to make trigger mailings, send letters, edit templates with variables.

I only have mailing lists + unsubscribes. Made through amazon. Fast, cheap (or even free, if you don’t send a lot, for example, 2k letters per day).
