Start with the promise
Before you promote anything, get the promise right, because the title and the outcome you offer are the single biggest lever on how many people register.
People do not sign up for a webinar; they sign up for the result it gives them. A title that names a clear outcome ("Build your first sales funnel in 60 minutes") will out-register a vague, agenda-led one ("A webinar about funnels") every time. Promise one specific thing the right person will be able to do or understand by the end, and make sure the rest of your registration page backs it up: the date and time with the timezone spelled out, who is presenting, and two or three bullets on what they will learn. Keep the form short, because every extra field you ask for lowers the number of people who finish signing up.
This guide is about driving traffic to that page and filling the room, not building the page itself. For the registration page structure and the rest of the funnel, see the webinar funnel guide, and for running the live event well, the how to host a webinar guide. Everything below assumes the promise and the page are in place.
Where registrations come from
The useful way to think about promotion channels is by who they reach: people who already know you, and people who do not. Your existing audience converts far better and costs nothing, so start there. New audiences are how you grow, and they take more effort or money.
For most hosts, email to their own list is the single biggest source of registrations. GoTo's webinar data puts email at around 57 percent of registrations, and Livestorm's 2026 benchmark found email drove the large majority of sign-ups on its platform, well ahead of any other channel. The catch is that email only reaches people who already know you, so to grow past your list you need partners and paid reach. Here is how the main channels compare.
| Channel | Reaches | How it works |
|---|---|---|
| Your email list | Existing | The biggest single source of registrations. Mail more than once and segment by interest. |
| Your website | Existing | A banner, a timed popup, a dedicated post, and CTAs inside related articles. |
| Your social and community | Existing | Organic posts, stories, a countdown, and your own group, capped at your current reach. |
| Partners and co-hosts | New | The most effective way to reach beyond your list. A guest brings their whole audience and adds credibility. |
| Affiliates | New | Let partners promote your webinar for a commission on what it sells. Reach without upfront ad spend. |
| Paid ads | New | Meta for broad and consumer topics, LinkedIn for B2B, Google for high-intent searches. Scales, but costs money. |
| Relevant communities | New | Niche forums, groups, and channels where self-promotion is welcome and genuinely on-topic. |
The one rule that holds across all of them is to not rely on a single channel. Lead with email because it carries most of your registrations, then layer on a partner or co-host to reach new people, and add paid or community promotion if your goal is to grow well beyond your existing audience. Partners deserve special attention: a co-host doubles the promotional reach, splits the work, and lends their credibility to your event, which is why cross-promotion is the highest-impact growth move on this list.
When to promote
Start promoting about two to three weeks out, and raise the cadence as the date approaches. The most important finding about timing is that you should not stop early, because most registrations arrive late.
According to GoTo's webinar data, roughly 59 percent of registrations happen in the week before the event and about 17 percent on the day itself. Livestorm's 2026 benchmark shows the same shape, with close to half of registrations landing in the final seven days and around 15 percent on the event day. Two separate platforms agreeing on roughly "half in the last week, around 15 to 17 percent day-of" makes this one of the more trustworthy numbers in the webinar world. The practical implication is clear: your heaviest promotion should be the final 48 hours, including a "we are starting today" message on the day. Quitting after the announcement email leaves most of your potential room empty.
On what day and time to actually hold it, the vendor benchmarks point to midweek, Tuesday through Thursday, in the late morning, around 10 to 11 in your audience's primary timezone. Livestorm's 2026 data, for instance, found Tuesday had the highest show-up rate. Treat these as starting points, not laws. The figures come from different platforms, they disagree at the decimal level, and the one thing they share is midweek and late morning. Pick a slot that fits your audience's working hours and timezone, and if you have run webinars before, test against your own numbers rather than someone else's benchmark.
The show-up problem
Here is the part most promotion advice skips: getting a registration is only half the job. A large share of the people who sign up will not be there when you go live, so you have to win the room you already sold. How large a share? Honestly, it is a range, and every published figure comes from a webinar platform reporting on its own users.
Read those numbers as the range they are, not as targets. They each come from one platform's own webinars, and real show-up swings widely with the audience, with B2B versus consumer, with free versus paid, and with whether the traffic was warm or cold. The reliable takeaway is the order of magnitude: plan for roughly half of your registrants not to attend live. That single fact should reshape how you think about promotion. The work does not end when someone registers; a good chunk of it, the confirmation and reminders that turn a sign-up into an attendee, only starts there.
How to fill the room
Fixing show-up comes down to making the event easy to remember and giving people a reason to be there live. The backbone is a reminder sequence that runs automatically from the moment someone registers.
A confirmation on signup, three reminders, and a live-now message. GoTo found webinars with at least three reminder emails attend at higher rates.
A few things make that sequence work harder:
One honesty note on that last point. Giving people a reason to attend live is good marketing; faking one is not. If you say the replay is limited or that a bonus is live-only, honor it. Fake countdowns and "this disappears forever" claims you do not keep erode trust, can run into advertising rules, and tend to backfire on the next event. Real, kept limits work better than invented ones anyway.
Then recover the no-shows
Because roughly half of registrants did not attend, your follow-up matters as much as the live event. Send the replay to everyone, honoring whatever terms you promised, along with a short recap and your next-step call to action. By some platform reports, on-demand viewing makes up close to half of all webinar viewing, so the replay email often recovers as much audience as the live room itself. Treat the no-shows as warm leads who were interested enough to register, not as a lost cause. If your webinar runs as an automated, always-on funnel rather than a one-time live event, the same reminders apply per registrant; see the evergreen webinar guide for that setup.
How to promote a webinar in 7 steps
Here is the whole process in order, from setting the promise to recovering the people who miss it.
-
Nail the topic, promise, and time
Pick one clear, outcome-driven title and choose a midweek, late-morning slot in your audience's timezone. The promise and the timing drive both how many register and how many show up.
-
Set up the registration page
Build a short page with one promise, a minimal form, the date and time with timezone, and the presenter. See the webinar funnel guide for the full build.
-
Build the promotion calendar backward from the date
Start about two to three weeks out and schedule a rising cadence that peaks in the final 48 hours and on the day, because roughly half of registrations arrive in the last week.
-
Promote across your channels
Lead with email to your list, your biggest single source of registrations, then add your website, social posts, and relevant communities rather than relying on one channel.
-
Recruit partners and co-hosts
Bring in a guest expert, co-host, or affiliate to promote the webinar to their audience. Partners are the most effective way to reach people beyond your own list.
-
Run the confirmation and reminder sequence
Send a confirmation with an add-to-calendar link immediately, then reminders at one week, one day, and one hour before, plus a live-now message, to turn registrants into attendees.
-
Follow up with attendees and no-shows
Send the replay, honoring whatever replay terms you promised, plus a recap and your next-step call to action, since about half of registrants did not attend live.
Common mistakes to avoid
Most webinar promotion fails in a few predictable ways, and almost all of them come from treating registration as the finish line. Watch for these.
Promoting once, then stopping. About half of registrations arrive in the final week and around 15 to 17 percent on the day. Quit early and most of your room stays empty.
Relying on a single channel. Email is your biggest source, but partners, social, and paid are what reach people who are not already on your list.
No reminder sequence. Without a confirmation and reminders at one week, one day, and one hour, registrations quietly fail to become attendees.
No add-to-calendar. One of the simplest, highest-impact show-up boosts, and one of the most commonly skipped.
A vague, feature-led title. A promise with no clear outcome registers poorly and shows up worse. Lead with the result, not the agenda.
Ignoring the no-shows. With on-demand viewing close to half of all webinar watching, skipping the replay-and-recap email throws away a large part of your audience.

Frequently asked questions
Start with the channels that reach your existing audience, because they convert best. Email to your own list is usually the single biggest source of registrations, followed by your website, social posts, and your community. To reach beyond your list, recruit partners or co-hosts who will promote to their audience, and consider paid ads on the platform where your topic audience lives. Promote over roughly two to three weeks with a cadence that ramps toward the event, since most registrations come in the final days. Promotion does not end at registration, though: about half of registrants do not show up live, so a confirmation and reminder sequence is what actually fills the room.
About two to three weeks out is a common starting point, with the cadence rising as the date nears. The important finding is that you should not stop early: according to GoTo's webinar data, roughly 59 percent of registrations happen in the week before the event and about 17 percent on the day itself, and Livestorm's 2026 benchmark shows a similar shape, with close to half of registrations in the final seven days. That means your heaviest push should be the last 48 hours, including day-of reminders that the session is starting soon.
The honest answer is that it is a range, and every published figure comes from a webinar platform reporting on its own users. ON24's 2025 benchmark reports about 57 percent of registrants attend, skewed toward B2B; Livestorm reports roughly 46 to 51 percent across mixed industries; and GoTo has long cited 40 to 50 percent. The numbers vary widely by audience, by B2B versus consumer, by free versus paid, and by warm versus cold traffic. The reliable takeaway is the order of magnitude: plan for roughly half of your registrants not to attend live, and design your reminders and replay around that.
Run a reminder sequence and make it easy to remember. Send a confirmation email with an add-to-calendar link the moment someone registers, then reminders about one week before, one day before, and one hour before, plus a short live-now message when you start. Adding the event to the registrant's calendar is one of the easiest ways to lift show-up. Opt-in SMS reminders get seen far more reliably than email and can add a meaningful bump on the day. Choose a time that suits your audience's timezone, build a little anticipation between registration and the event, and give people a real reason to attend live, such as a Q and A or a resource handed out during the session.
The vendor benchmarks point to midweek, Tuesday through Thursday, in the late morning, around 10 to 11 in the audience's primary timezone. Livestorm's 2026 data, for example, found Tuesday had the highest show-up rate. Treat these as starting points rather than rules: the figures come from different platforms, they disagree at the decimal level, and the only thing that holds across all of them is midweek and late morning in your audience's timezone. The best move is to start there and test against your own audience, especially if they span multiple timezones.
A common and effective cadence is a confirmation email on registration plus three or four reminders: about one week before, one day before, one hour before, and a short live-now message at the start. GoTo found that webinars with at least three reminder emails see higher attendance, so sending multiple reminders is one of the more reliable ways to raise your show-up rate. Pair the emails with an add-to-calendar link and, for registrants who opt in, a day-of text message, which tends to get seen faster than email.
For most hosts, email to their own list is the largest single source. GoTo's data puts email at around 57 percent of registrations, and Livestorm's 2026 report found email drove the large majority of registrations on its platform, well ahead of any other channel. The catch is that email only reaches people who already know you. To grow beyond your existing audience, the most effective channel is partners and co-hosts who promote to their lists, supported by paid ads and relevant communities. A healthy promotion plan uses email as the backbone and partners plus paid to expand reach.
Follow up, because they are still part of your audience. Send the replay, honoring whatever terms you promised, such as a limited window if you said the replay would be limited, along with a short recap and your next-step call to action. On-demand viewing accounts for a large share of all webinar viewing, by some platform reports close to half, so the replay email often recovers as much audience as the live session itself. Treat no-shows as warm leads who were interested enough to register, not as a lost cause.
