Do you guarantee that I won’t be blocked in hotmail, yahoo, etc?
Neither us, nor any other company, can guarantee 100% input into a particular provider, it is something that only depends on them. The rules that filter spam email are personal to each vendor and are not public. However, our platform is ready and designed to meet the provider requirements in terms of delivery speed, IP management, and many other factors that determine the entry or not of the emails. The most important thing for the user to enter all suppliers well is to have and maintain the subscriber list clean.
