Aivie is modular as an application and uses the latest technical possibilities to carry even very large loads. The various components are all virtualized and can scale up in a short time. So it is no problem if, for example, an email Campaign brings a lot of traffic in the short term.
The modular setup also allows a dedicated server to be provided for certain tasks. This way, tasks are clearly distributed and the frontend is not affected by background work, for example.
From 100,000 contacts, at the latest, it makes sense for us to take a close look at the individual setup and also discuss the price. We will be happy to discuss the individual enterprise setup with you.
