In this lesson, you'll learn how to set up a Welcome Series on WhatsApp. We'll guide you through installing WhatsApp as a channel, creating a contact list, and setting up a sign-up form linked to that list. You'll create a Journey triggered by new sign-ups, configure a series of welcome messages to be sent at intervals, and finalize the Journey setup. By the end, you'll be ready to publish and activate your WhatsApp Welcome Series.
