You measure the success of your event communication via these KPIs. Reach: how many unique people you address per channel (email, LinkedIn, website). Engagement: the number of clicks on your message (click-through rate). Conversion: the number of people who sign up after your message (sign-up rate). Turnout: the share of registrants who actually come. Aim for at least 80%. Quality: is your audience in the room? Attribution: which channel brings in the most sign-ups? Track everything in one dashboard, for example Google Sheets. If you're off course, adjust along the way: more email work, more LinkedIn, more personal contact. Compare per event and learn from last time. Live Impact gives you a ready-made measurement template.
