Why registrants sign up and then don’t show up
Seven competing explanations circulate. Nobody has ever ranked them against each other. This page ranks them, names a source for every one, and marks plainly which ones we address and which ones we do not.
There is no single reason, and the popular one — they forgot — is not the reason the audience itself gives. In the public threads where operators and attendees argue about this, seven separate explanations get offered: the replay, no time, webinar fatigue, the wrong topic, splitting one event across several time slots, spam filtering, and registrants who were never invested. The strongest of them by a wide margin is the replay — and it is the one that no reminder product, including ours, fixes.
What could be the reasons why people sign up and then don’t show up?
That is not our phrasing. It is a non-profit marketer’s, writing about monthly webinars that pull 150–200 registrations across three time slots and get about 50 people showing up live. After being asked why it mattered, he restated the question himself in the comments[1]:
“It’s not so much to get so many people to watch, I’m moreso asking, what could be the reasons why people sign up and then don’t show up and how can we incentivize them to come.”
He got 32 replies and no ranking. That is the whole state of the public record on this question: several confident theories, argued in parallel, never weighed against one another. Below, each one is listed with the strongest evidence anyone has actually put behind it — and with an honest column saying whether a pre-webinar call and SMS system touches it at all.
| Explanation | Strongest evidence anyone has put behind it | Does our system address it? |
|---|---|---|
| The replay — “everyone sends a recording now” | 42 upvotes, the highest-voted answer anywhere in this research, from an attendee explaining his own behaviour | No. We can find out whether it is your reason. We cannot make a recorded lecture feel worth attending live. |
| No time — webinars are first off the priority list | Stated repeatedly by attendees rather than by operators, in their own words, unprompted | This is what a micro-commitment call is aimed at. Whether an AI voice call reproduces the effect a human call had in the research below is untested and unpublished. |
| Webinar fatigue | 18 upvotes, and used in the threads as settled shorthand rather than as a hypothesis | No. Nothing sent before an event fixes an audience that is tired of the format. |
| Wrong topic for that audience | Raised by several operators, including one whose own sub-5% webinar he attributes to a topic that was too broad | No. That is an offer problem, and a call the week before does not change it. |
| Too many time slots | Four separate commenters told the same operator, in one thread, to drop three sessions and run one | No. That is a scheduling decision you make before anyone registers. |
| Spam filters eating the reminders | Raised by the operator whose live attendance fell from ~40% to ~15% on an unchanged email sequence. Nobody in that 56-comment thread resolved it. | No. We do not fix email deliverability, and we do not claim to. |
| They were never invested — “zero intention of attending” | Stated flatly by two operators, one of whom treats no-shows as self-selecting out | No. If it is true of most of your list, you have a traffic problem, not a show-up-rate problem. |
How this ranking was made, and what it is worth
Do they just forget?
The entire reminder industry is built on the assumption that they forgot. Operators say it out loud — “People usually forget they registered to a webinar”[2] — and yet forgetting is the one explanation that nobody in those threads upvoted.
The largest randomised test of that assumption does not come from marketing. In a 287,228-person field experiment published in Psychological Science[3], a standard encouragement phone call had no significant impact on turnout at all. A call that got the person to say what time they would go, where from, and what they would be doing beforehand moved turnout by +4.1 percentage points among the people the call actually reached.
Read that as a correction to the forgetting theory, not as a promise. It is a voting study, not a webinar study, and no published research reports whether an AI voice call reproduces what a human caller did there. That gap is the bet we are making, and saying so is more useful to you than a number we cannot stand behind.
The mechanism itself — the micro-commitment, in the operators’ own word for it — is covered in how to increase webinar attendance. This page is only about causes.
“People really love signing up for things they have zero intention of attending” — is that just it?
“i spend my days debugging salesforce workflows and even that feels less tedious than trying to fix a webinar conversion rate that’s tanking for no reason. people really love signing up for things they have zero intention of attending.”

A second operator in the same thread takes the further step and treats it as a filter rather than a problem: “I’m not too worried about show-ups. If they don’t show, they’re not invested in it anyway, or could watch on-demand.”[5] It is a coherent position, and it is the strongest argument against buying anything at all from anyone in this category — ourselves included.
The best counter-evidence in the whole corpus comes from an events operator with six years of monthly data, reporting the same audience under two different registration conditions:
“Our data from the past 6 years of monthly online events is a 70% no show rate from our free registrations and a 15% no show rate from our paid registrants. Consistent across the board as far as topics, time of day, day of the week, etc.”
— u/krissyface, r/EventProduction, 2026-07-06[6] (one operator, self-reported, no control group)
Take the numbers as one operator’s self-report, because that is all they are. What they suggest is still the important part: intent is not a fixed property of a registrant. It moves with what you ask of them at sign-up. Whether charging is the right move for your business is a separate question, and this page does not answer it.
Is the format the problem, or is it execution?
“What we’re still trying to figure out: is the format the problem, or is it execution? … The bar for ‘worth my 45 minutes’ seems to have gone up significantly.”
— u/delverisk, r/AskMarketing, 2026-05-07[7]
Both answers are held with equal confidence by people who run webinars for a living, which is itself the finding. On the format-is-finished side:
- “i don’t think i’ve joined a webinar in ten years”[8] — 8 upvotes.
- “I want AI to summarize webinars for me so I don’t have to attend.”[9] — 14 upvotes.
- “In 2026 nobody is going to sign up and sit through a webinar.”[10]
Against it, in the same thread as the first two, one marketer reports of a client around 60% attendance, 700–1,000 people a month, in the baby and parenting niche[11] — self-reported, no method disclosed — and draws the conclusion himself: “depending on the niche, webinar fatigue is a real thing.”
So the honest answer is that the question resolves per audience, not in general. The people who have stopped attending webinars and the people who attend one every month are both real, and they are not the same list. Which one you bought is the thing worth finding out.
What is webinar fatigue, and is it real?
Webinar fatigueis the audience’s own shorthand for having sat through enough webinars that another one is no longer worth an hour. It is not a vendor coinage. It appears in the threads as settled language, used without explanation and upvoted:
“Your topics don’t work with your audience. No one has time to sit through another webinar. Webinar fatigue”
— u/cjroxs, r/marketing, 2026-03-12[12] (18 upvotes)
Notice what that one comment does: it names three of the seven explanations in a single breath — wrong topic, no time, fatigue — and treats them as interchangeable. That is exactly why nobody has ranked them. Alongside it sits the same thread’s workload version of the argument — “webinars and trainings are the first things to fall off the priority list”[13] — which is fatigue described from the calendar rather than from the content.
Verdict: real as a stated attitude, unmeasured as an effect. The published webinar benchmarks segment attendance by company revenue, by job seniority and by use case. None of them segments it by how many webinars the registrant has already sat through, so there is no number to quote here and we are not going to invent one.
“Registration and people who show up are completely different topics” — so which number should I optimise?
The phrasing is an operator’s[14], and it is better than the language most vendors use for the same idea. Registrants and attendees are two different populations, and every number you can watch tells you about one of them while hiding something about the other.
| Number | What it tells you | What it hides |
|---|---|---|
| Registrations | Whether your ad and your registration page work | Whether a single one of those people intended to attend |
| Show-up rate | What share of registrants attended live | That it moves when your traffic mix moves — which is most of why published benchmarks disagree with each other |
| Live attendees | How many people were actually there live | What each of those people cost you to get there |
| Cost per booked-and-attended call | What one person who actually turned up cost you | Whether they buy. That is a separate rate, and you have to measure it on your own offer |
If the question underneath yours is really “is my show-up rate normal?”, that is a different page: webinar show-up rate by traffic source covers what the published benchmarks actually measure, and why the paid-traffic number everyone quotes does not exist.
The strongest explanation has its own page
Frequently asked questions
In the public threads behind this page the most strongly agreed-with reason is the replay: people know a recording is coming, so live attendance stops being necessary. It carried 42 upvotes, more than any other explanation found. That is a measure of agreement, not of cause — no published study ranks these causes against each other.
Often the offer. Operators in this corpus attribute their own failures to a topic that was too broad, to an audience that had aged out of the format, and to running three sessions where one would have carried more urgency. A pre-webinar call and SMS system does not change any of those, and we would rather say so than sell you a reminder layer for an offer problem.
Two operators in this research ran the full stack — email, SMS, and a human phone call minutes before — and still reported roughly 20% and under 5% attendance. The reminder ladder is commodity. What the evidence supports is not more reminders but a different kind of contact; that argument sits on the increase-webinar-attendance page.
It exists as a widely shared and upvoted attitude among attendees, and it is their own term, not a vendor's. It does not exist as a measured effect: no published webinar benchmark segments attendance by how many webinars a registrant has already attended, so nobody can tell you how many points it costs you.
Three operators advise against leading with it and none of them has published any before-and-after data. Nobody has measured it, and neither have we. The replay problem page lays out each option, who proposed it, and exactly how thin the evidence is.
One of the seven, partly: the intent gap between registering and turning up, which we work on by getting the registrant to state in their own words when they will join and what they will be doing right before. We do not fix your replay policy, your topic, your time slots, your email deliverability, or an audience that never intended to come. The second thing you get is the answer to this page's question for your own list, in your registrants' own words.
You run a webinar. We come in and increase your show-up rate and your post-webinar sales, with our AI voice and SMS system — and you finally know why every registrant signed up, because the agent asks and the answers come back in their own words. If that is worth twenty minutes, book a call. If you would rather keep reading: the biggest cause on this page is unpacked in the replay problem, and the fixes that survive contact with evidence are in how to increase webinar attendance.
