A no-show is a booked meeting the prospect simply does not attend. No message, no reschedule — the rep and the account executive show up to an empty calendar slot. No-shows are the direct enemy of show rate, because every one of them lowers the share of meetings that actually happen. They also burn the AE's time, which is why teams treat a high no-show rate as a problem with qualification or follow-through, not bad luck.
In plain English
A no-show is a meeting that was booked and then quietly never happened. You got the yes, put it on the calendar, and the person did not show up. The point of confirmation emails is to make this rare, because when it happens it costs your team an hour and a credibility point.
Why it matters to you
No-shows are partly in your control. A rep who confirms twice, sends a clear agenda, and books meetings with genuinely engaged prospects sees far fewer. If you want to look like a pro in your first sales job, treat no-shows as a metric to beat rather than a fact of life — your AE will notice, and your show rate will be the number that makes the case for you.
