What changes when a team owns WhatsApp
One person sending a broadcast when the shop is quiet isn't a marketing programme. Once a team owns the channel, it needs what email and paid social already have: a calendar, a brief for each send, an approval step, a budget, and a report that someone actually reads.
The mechanics each have their own page: broadcasts, drip sequences, Click-to-WhatsApp ads. This page is about the operating rhythm around them: who writes, who signs off, what the month costs, and how you tell whether it worked.
Roles matter more than they look. Gallabox's Basic plan has an owner role only. Essential adds member, admin and owner roles, and Advanced adds custom roles. Decide early who is allowed to send to the full list, because one wrong broadcast reaches everyone at once.
