# Automation Flows - Triggering messages through the Switch

In this article, we will explore how to create an automation flow in SprintHub to send mass messages in a strategic and secure way.\
\
We will use a **smart filter segment**, which automatically adds leads with a valid WhatsApp number, ensuring the target audience is qualified.\
In addition, we will configure the flow using the alt**ernator and the wait block, f**fundamental tools for spacing out sends and avoiding platform penalties.

By the end of this guide, you will be able to implement this strategy in SprintHub, optimizing your communication and expanding the reach of your messages without compromising your account's reputation.\
