See where webinar registrants come from

Using my Livestorm data, show me where the registrants of [WEBINAR NAME] came from: its next session, or its most recent one if none is coming up or I ask about the last one. Count registered participants only: leave out team members and guest speakers, and say how many you left out. 1. Group them by UTM source and medium, then by campaign. Rename sending tools into channels I'd recognise (for example an email tool's link becomes "email to customers" or "email to leads", using the campaign to tell them apart), merge one-off tags into the matching channel, and ask me if the naming isn't obvious. 2. For registrants with no UTM, use their referrer to guess the channel when you can, and mark those as guessed. Put the rest in a "No UTM" row with their referrers. 3. For each channel, give the number of registrants, its share of the total, the share using a business email address (not Gmail, Outlook, Yahoo and the like; count placeholder or unknown addresses as non-business), and how many registered in the 7 days before the session (or the last 7 days if it hasn't happened yet). 4. Show a cumulative registration timeline by channel, day by day (as a chart if you can make one). 5. If the session has already taken place, add the show-up rate and replay views for each channel. Start with the top channel and one line on what the numbers say, then the table, then the timeline. End with one suggestion, such as a channel to push or a link missing its UTMs. Don't show names or email addresses.
