You run a webinar. We increase your show rate and your post-webinar sales, with our AI voice and SMS system.
AI webinar attendance is a done-for-you system that works your registrant list for you: we text every registrant who opted in, call them before the webinar to get a concrete plan out of them, and then work the attendees and the no-shows while your offer is still open. Every call says it is an AI assistant in the first seconds. You get back two things - the people who turned up, and a written record of why each registrant signed up, in their own words.
It is not a reminder tool. Two reminders do beat one, and that is roughly where the reminder ladder stops paying. What the evidence actually supports past that point is asking the registrant a question they have to answer.
What Actually Makes Someone Show Up?
Not being reminded. Being asked. The strongest randomised evidence anyone has on this question comes from voter turnout, and it separates the two cleanly: a call that helped a person work out when they would go, how they would get there and what they would be doing right before moved behaviour. A call that simply encouraged them did not.
Operators already have a word for the small version of this, and it is a better word than ours: the micro-commitment. Ask one question the registrant has to answer, and they are now defending a position they authored themselves rather than filing away a notification.
Three caveats that travel with that number, every time we use it
What Do You Get Besides a Higher Show Rate?
You know why every registrant signed up, in their own words. Because the system asks rather than announces, every webinar produces a document: hundreds of stated reasons, in the language your market actually uses, grouped so you can see what keeps coming up.
That is the asset most reminder tools structurally cannot produce, because they never ask the registrant anything. It is also the part that does not depend on a webhook, a platform integration or any timing guarantee - which is why we lead with it rather than with a show rate. It feeds the next landing page, the next offer, and the objection list your closers work from.
Their words, not your categories
Free-text reasons, not a dropdown. What people write when nobody gave them options is the part you cannot get from your registration form.
Per webinar, not per quarter
The document arrives with each run, so you can see the market move between one webinar and the next instead of once a year.
Useful even if nobody shows
A no-show who told you why they registered is still worth something. This is the one output that survives a bad attendance week.
How Does It Run, From the Registration Form to the Offer Window?
Four phases. You can buy them separately, and most operators start at phase four, because that is the one nobody has the hours to finish by hand.
Phase 1 - the registration form, before anyone is contacted
Channel consent is won on the form, not on the call. We read what your registration form actually authorises - which channels, for which purpose - and tell you plainly if it does not yet authorise the follow-up you want to run. In several EU countries that consent is the only lawful route to an automated call, so this step is part of the deliverable rather than the fine print.
Phase 2 - the SMS thread, right after registration
Every registrant who opted in gets a text that asks one question instead of repeating the date. That is the micro-commitment operators already talk about: a registrant who has answered something is in a thread, not on a list. We attach no performance number to this leg, because the pooled evidence on two-way SMS versus standard care is null (Odegard 2022, PLoS One: RR 1.03, 95% CI 0.95-1.12, across 5 trials all set in Sub-Saharan Africa) and we are not going to pretend otherwise.
Phase 3 - the call before the webinar
The agent says it is an AI assistant in the first seconds, then helps the registrant make a concrete plan: when they will join, on what device, where they will be, what they are doing right before. That plan question is the mechanism. Timing is configurable and the default is humane rather than immediate - being contacted the moment you fill in a form reads as surveillance, not service.
Phase 4 - attendees and no-shows, inside the offer window
This is the phase most operators never finish. A 500-registrant list at three to nine minutes a call is roughly 40 to 55 working hours of dialling before anyone has closed anything, and a typical offer window is 72 hours. That is arithmetic, not an efficacy claim. The agent confirms, qualifies and books; your closers take the actual sales conversation.
Each phase has its own page: webinar reminder calls covers phases two and three and what the evidence on reminders really supports, post-webinar follow-up calls covers phase four and the capacity arithmetic behind it, and webinar registrant consent covers phase one and what your form has to say before any of it can run.
Is a Blast Reminder the Same Thing as a Conversation?
The thing we are competing with is the one-way blast, not SMS itself. We send SMS too. The difference is that theirs is a notification you swipe away and ours is a question you answer.
| What you are comparing | A one-way blast reminder | A conversation (what we run) |
|---|---|---|
| What it asks of the registrant | Nothing. It is a notification | One question they have to answer |
| What you learn from it | A delivery report you cannot verify against behaviour | Why each person registered, in their own words |
| Who it appears to be from | A no-reply sender | A named assistant that says it is an AI in the first seconds |
| What happens if they reply | There is usually nowhere to reply | It is read, answered, and kept |
| Before the webinar | The date and the link, repeated | When they will join, on what device, from where |
| After the webinar | The recording link, to everybody | Attendees and no-shows worked separately, inside the offer window |
| Opting out | A footer link, per channel | Spoken or typed - and it stops every channel at once |
What Does a Realistic Show Up Rate Look Like?
Lower than the number you were quoted. The published figures range from about 21% to about 60%, and the spread is not noise - it is four or five different things being measured and called the same thing. The high end almost always measures enterprise marketers emailing their own house list, which is a different population from an operator running paid traffic to a masterclass.
The sources below are the structurally comparable ones. They converge on a 21% to 34% band, which we use as a planning assumption rather than a benchmark. All of them are US or English-language sources, all are vendor or practitioner data rather than peer-reviewed, and there is no published show-rate benchmark segmented by traffic source anywhere. If you need your own number, measure your own list.
What the strongest evidence on reminders actually supports
The best-quality evidence in this whole area is not from webinars at all - it is from healthcare appointments, where reminders have been tested in randomised trials at scale. Here is what it says, including the parts that do not help us.
| The common claim | What the evidence says | Source |
|---|---|---|
| A text reminder lifts attendance | Yes, modestly: risk ratio 1.14 (95% CI 1.03 to 1.26) against no reminder, 7 studies, 5,841 participants | Cochrane systematic review, 2013, healthcare appointments |
| A phone call beats a text | No detectable difference: risk ratio 0.99 (95% CI 0.95 to 1.02), 3 studies, 2,509 participants | Cochrane systematic review, 2013 |
| More reminders keep helping | Two beat one and then it stops: 4.4% missed appointments for a 3-day plus 1-day reminder, against 5.3% and 5.8% for a single reminder | Steiner 2018, three-arm randomised trial, 54,066 patients |
| The reminder call is what lifts attendance | A standard encouragement call had no significant impact. The version that helped people form a concrete plan lifted turnout 4.1 points among those reached | Nickerson and Rogers 2010, N = 287,228 |
| AI voice beats SMS | Nobody has published this, and the closest comparison points the other way. We do not claim it | No source exists |
Sources, in order: Gurol-Urganci et al., Cochrane Database of Systematic Reviews, 2013; Steiner et al., American Journal of Managed Care, 2018; Nickerson and Rogers, Psychological Science, 2010. The healthcare studies measure appointment attendance rather than webinar attendance, and we use them because they are the best-designed evidence available, not because a clinic visit is a webinar.
What Does This Not Do?
This section is longer than the promises section, deliberately. In a category where almost every claim is a bare assertion, the fastest way to be believed is to publish the limits first.
It cannot fix cold traffic
If the registrants came from an audience that never wanted the webinar, no reminder ladder and no call repairs that. Webinars are not a cold-lead strategy and we are not going to sell them as one. Fix the traffic first; this system works a list that already raised its hand.
It cannot fix the offer
Attendance is upstream of the pitch. Getting more of the right people into the room changes who hears the offer, not whether the offer converts. If the offer does not sell to the people who already attend, more attendees will not rescue it.
It cannot beat the replay
In the operator communities we read, the most common stated reason for skipping a live webinar is that a recording is coming - not forgetfulness. A call does not out-argue that. The one counter we found anywhere in the research is structural: run the live session as a working session people have to be present for, rather than a lecture.
We will not promise you a show up rate
No number appears anywhere on this page as a promise, and none will appear in a proposal either. There is no published show-rate benchmark segmented by traffic source, so anyone quoting you a guaranteed rate for your traffic is quoting you a number that does not exist.
We do not claim voice beats text
In the best head-to-head comparison available, text message reminders and phone call reminders performed the same. We run both because they do different jobs, not because we can show you that a call wins.
We do not know how your registrants will feel about it
Disclosure is our position because buyers demand it and because Article 50 becomes applicable across the EU on 2 August 2026. But we found no published account of how people react to receiving a disclosed AI call. It is untested rather than established, and we would rather say so than tell you people do not mind.
It is built for scheduled live webinars
Evergreen and automated webinars are a different product, not a setting. When the gap between registration and session is often minutes, a pre-webinar call has nowhere to sit. If you run evergreen, say so on the call and we will tell you honestly whether there is anything here for you.
We do not sell calling people who left mid-session
It is the feature everyone wants and almost no platform can support. Most webinar platforms publish no dependable real-time leave event at all, and on the one that does, the event is not reliable enough to build a promise on. What we will do instead is check the roster at pitch time and work the gap.
There is no case study on this page
There are no logos, no testimonials and no client results here, because publishing ones we do not have is how this category earned its reputation. The honest test is a holdout on your own list: split it, run one half, compare. That is real; everything else is a story.
Can You Legally Call Your Own Webinar Registrants?
Jurisdiction
The short version: registering for a webinar is not, by itself, consent to be called. Article 13(1) of the ePrivacy Directive allows the use of automated calling systems for direct marketing only in respect of subscribers or users who have given their prior consent. Prior means before the call, which in practice means it has to be captured on the registration form. That is why phase one of this system is a form review rather than a disclaimer.
So the honest shape of the offer is this: we run the follow-up your registration form authorised, and we will tell you if your form does not authorise it yet. In several EU countries that consent is the only lawful route to an automated call, so getting the form right is the deliverable, not the small print.
The AI says so, on every call
Article 50 of the EU AI Act requires that people be informed they are interacting with an AI system, and it becomes applicable across the EU on 2 August 2026 - we already do it on every call. The disclosure is built into the agent and delivered at the start of every call, in the call language.
One opt-out stops everything
Article 21(3) of the GDPR is absolute: where someone objects to processing for direct marketing, the data is no longer processed for that purpose. An objection spoken on the phone stops the SMS and the email too.
There is a gate consent cannot open
Some countries also regulate which number an automated campaign may call from, and that rule is consent-agnostic - having permission does not open it. We tell you where it is shut before you buy, not after.
The detail lives on two pages: what your webinar registration form has to say and the per-country picture across the EU and UK. For the wider European picture on automated outbound generally, see our European AI calling compliance guide and EU data residency page. On your registrant data we act as a processor under a GDPR Article 28 agreement; you remain the controller, and you own what the form said.
Who Is This Actually For?
Operators who run scheduled live webinars to a list they paid to build, and who sell something at the end of them: course creators, coaches, consultants, B2B marketers running demand-gen sessions, and the agencies who run all of the above for clients. The common feature is not the webinar, it is the offer window afterwards and the fact that nobody has the hours to work it.
If your bottleneck is booking meetings rather than filling a webinar room, the same voice system does that job on AI appointment setting and as a fully done-for-you outbound service. If you want to understand the underlying technology first, start with what an AI voice agent is.
