The UTM Source is a dropdown with predefined channels in HubSpot’s Tracking URL Builder. When selecting Social or Paid Social from the Source field, I see that the list has been updated compared to two months ago: 3 added (TikTok, WeChat, and Weibo) and 18 removed, among which WhatsApp.
Reports > Analytics Tools > Tracking URL Builder:
So, the sad thing is that we cannot make UTM tracking URLs for WhatsApp campaigns from scratch via the Hubspot UTM builder anymore.
I would like to better understand HubSpot’s motive and frequency for implementing such updates.
