hi,I am interested in your service, how to contact youWell, in general, it certainly depends on many factors, such as the country, for example, the target audience, and overall goals. Our service now provides for the Viber bulk mailing and every day all the volumes of mailings are filled, we have a lot of regular customers, I think if they were ineffective, we would fail. We have been working for more than 2 years in this market![]()
