What is the fastest way to fill an event?
Every channel fills some events. The question is how fast it works for yours, and what it costs while you wait. Here's how the 9 main ways stack up when the event is 6 weeks out, not 6 months.
| Channel | Time to first registrations | What it costs | Best when |
|---|---|---|---|
| Past attendees and your own list | Hours to days | An email and a few personal notes | You've run events before or have an engaged list |
| Personal outbound on social channels | Days | Your team's time or a system | You can name your ideal attendees by title, company or community |
| Your team and speakers inviting contacts | Days | A short invite kit and a nudge | Sales reps, speakers and partners already know the right people |
| Cold email | 1 to 2 weeks | Domains, warmed inboxes, a sender tool | You have a large, well-defined list and a clear event promise |
| Partners and sponsors sharing | 1 to 3 weeks | A co-marketing deal or a revenue share | Someone else already owns the audience you want |
| Communities and groups | 1 to 4 weeks | Time spent being useful in threads first | Your attendees gather in subreddits, Facebook groups, Slack or Discord |
| Paid ads | Days, once the page converts | Ad spend while you test | Your event page already converts warm traffic |
| Organic content | 3 to 8 weeks | Hours every week | You post regularly and have a following in the niche |
| PR, listings and event directories | 2 to 6 weeks | Pitching time and listing fees | The event is public, large or newsworthy |

Rough ranges, not a study. Event size, ticket price and how well your brand is known will move them.
Look at the top 3. In each one, you or someone you know starts the conversation. Everything lower down waits for a stranger to notice a post, an ad or a listing and decide on their own. For the full list of tactics that turn that attention into sign-ups, read how to increase event registrations.
Why start with past attendees, and why isn't your list enough?
Your past attendees already said yes once. They know the format, they know you, and many of them know someone who should come. Re-invite them personally before you announce anywhere else, and ask each one who they'd bring. Then email the rest of your list.
Email still carries most event promotion, and for good reason: it reaches people who asked to hear from you.

The catch is reach. Your list is the people you already know. If your goal is new customers in the room, or a type of attendee you've never met, a list can't produce them. It also wears out with every repeat announcement. Your list fills the base. Personal outreach fills the gap between the base and your target.
How many registrations do you need to fill the room?
Work backwards from the seats, not forwards from the invitations. Not everyone who registers turns up.

So a free in-person event loses about 1 in 4 registrants, and a webinar loses about half. PheedLoop's own planning rule is to plan for 80% of expected attendance at paid events and 70% at free ones. Now run the math for your event.
| Step | Free in-person event | Webinar |
|---|---|---|
| Attendees you want | 60 | 100 |
| Show-up rate | 70% (PheedLoop planning rule) | 47.7% (Livestorm average) |
| Registrations you need | 86 | 210 |
| Invitation to registration rate (assumption) | 10% | 10% |
| Personal invitations to send | 860 | 2,100 |

Show-up rates from PheedLoop (free live events) and Livestorm (webinars). The 10% is an illustration only: say 25% of invitations get a reply and 40% of those replies register. Swap in your own rates.
That last row is why so many event pages end up half full. Organizers send a few posts and 1 email when the target needs hundreds of personal invitations. To plan with your own event type, use the numbers in our event attendance rate benchmarks.
Which channel do your ideal attendees actually use?
The best invitation channel is the one your dream attendee opens every day. A plant manager doesn't check TikTok for event invites. A creator doesn't read InMails. Match the channel to the person:
- LinkedIn: executives, managers and professionals, for conferences, roundtables, executive dinners and webinars. You can invite only 1st-degree connections to a LinkedIn Event, up to 1,000 invitations a week shared across all your events, so connection requests and messages do the heavy lifting.
- Instagram: founders, coaches, creators, agencies and local business owners, for workshops, launches and in-person meetups.
- Facebook: local business owners, trades and members of niche groups, for open houses, training days and local seminars.
- X: SaaS and AI founders, developers and investors, for demo days, launches and Spaces.
- TikTok: creators, DTC brands and consumer-facing businesses, for workshops, live sessions and pop-ups.
- Reddit: practitioners who already discuss your event's topic in niche subreddits, especially developers and specialists.
- Threads: tech founders, agency owners and creators who moved over from Instagram.
- Discord: builders and community members, for hackathons, AMAs and virtual meetups.
- Cold email: almost anyone with a work address. Best for large, well-defined lists, like every head of operations in a region. Read our event invitation email examples before you send.
Most business events have 2 or 3 strong channels, not 1. Running them together means more invitations into the same market without pushing any single profile too hard.
What should your first event invitation say?
Business attendees don't go to events to be sold to. In Freeman's 2025 survey of 1,022 attendees, discovery was the top reason to attend, and almost nobody went to buy on the spot.
58%
of attendees go to events to discover new products and solutions; only 6% go to make a purchase decision

So the invitation promises discovery and good company, not a pitch. It has 1 job: show you picked this person on purpose, then ask a small question.
Hi Mark! We're hosting an exciting event on the future of logistics with amazing speakers. Register here: [link]. Hope to see you there!
Hey Mark, saw your post about cutting empty miles between your Dallas and Houston depots. We're hosting 20 fleet ops leads for breakfast in Dallas on March 12, and 2 carriers are sharing their routing numbers. Want me to save you a seat?
The second one names the reason he was picked, says who else is in the room and gives a date. No link yet. The link comes when he says yes, which also makes the registration feel like his decision. For more scripts by channel, see our LinkedIn event invitation messages.
What happens when someone replies?
A reply is where most invitations die. People ask a question, wait a day for the answer and forget they ever asked. Answer within minutes, answer what they actually asked, and make the next step tiny. Here's what that sounds like:
Sounds interesting. Is it free? And who's actually going to be there?
It's free, breakfast included. So far it's 14 ops and logistics leads from Dallas carriers and shippers, plus Dana from Lonestar Freight and Raj from a regional 3PL, who'll walk through their routing numbers. Want me to register you? I just need the email you'd like the calendar invite on.
Sure, mark@northlinefreight.com. Can I bring my planning manager?
Done, you're both on the list. The invite with the address and parking is on its way. What's her name, so her badge is right?
The AI conversation agent answers the price and the who-else question straight, adds 1 concrete detail and asks for the smallest possible yes. Then it turns 1 registration into 2. We break down how AI handles every common reply in AI for event marketing.
How far in advance should you start inviting people?
Earlier than you think, and keep going longer than you think. In Zoom's webinar data, the top 1,000 webinars by attendance had a 13-day median promotion window, against 9 days for lower-attended ones. Most people register within 2 to 14 days of the event.
In-person events stretch further. PheedLoop's data on 467 live events puts the median registration lead time at 16 days for free events and 41 days for paid ones. And late registration is normal: Livestorm found 49.7% of webinar registrations land in the final 7 days.
A practical rule: start personal invitations 6 to 8 weeks out for a paid conference, 3 to 4 weeks out for a free in-person event and 2 to 3 weeks out for a webinar. Then keep inviting through the last week. Our 8-week event marketing plan lays it out week by week.
How do you get registrants to actually show up?
A registration is a promise, not an attendee. The gap closes with reminders that feel personal and an easy way out of a clash. Zoom found 68% of webinar no-shows missed the event because of a scheduling conflict, so the best reminder offers a fix, not just a time.
- 1Confirm right away, on the channel they said yes on, with the date, the place and a calendar invite.
- 2Send something useful a week out: the agenda, who's speaking and 1 thing they'll leave with.
- 3Check in personally 2 days before, and offer to move them to another date if it clashes.
- 4Remind them the morning of, by email and SMS, with the address or the join link.
- 5Message no-shows the same day with the recording or the next date. A kind note often brings them to the next one.
Hey Mark, quick one before Thursday: you and Priya are both on the list for the 8:00 breakfast at the Adolphus. Still good? If something came up, tell me and I'll hold 2 seats at the April session instead.
The full sequence, with timings and copy, is in how to reduce event no-shows.
How MyBazooka handles this
MyBazooka runs the invitation and conversation part of this with AI, across 9 channels: LinkedIn, Instagram, Facebook, X, TikTok, Reddit, Threads, Discord and cold email. It learns your events in 1 conversation: it reads your website and asks who your ideal attendees are and what makes each event worth the trip. Then its agents run hundreds of queries at once inside Sales Navigator, groups, communities, subreddits and Discord servers, plus post commenters, followers and event-adjacent sources, and collect thousands of qualified attendees.
Every one of them is researched individually (profile, posts and company) before a word is written. Invitations go out as personal connection requests, DMs, InMails, comments and cold emails in 1 campaign, inside safe daily limits per profile. When someone replies, the AI conversation agent answers questions about the agenda, speakers, location and price, qualifies them, handles objections and follows up when they go quiet, until they're registered by MyBazooka. Native thank you pages get each attendee warmed up, and personal AI reminders on the channel they registered on, plus email and SMS, get them to show up.
Every message, reply and registration feeds back in, so the system keeps what fills rooms in your market and drops what doesn't. Pricing starts at $2,897 a month, month to month, and you can cancel any time. Or book a strategy session and watch it invite your own ideal attendees.
Questions people ask
How do you get more people to attend an event?
Re-invite past attendees and your own list first, then send personal invitations to the exact people you want in the room, on the channels they use every day. Back that with speakers and partners sharing it, and a reminder sequence so registrants actually show up. Direct invitations are the fastest lever you fully control.
How far in advance should you start promoting an event?
For webinars, about 2 to 3 weeks: Zoom found the best-attended webinars had a 13-day median promotion window. PheedLoop puts the median registration lead time at 16 days for free live events and 41 days for paid ones, so start 3 to 4 weeks out for free events and 6 to 8 weeks for paid conferences. Keep promoting until the start, because many people register in the final week.
What is the fastest way to fill an event?
Personal invitations, first to people who already know you, then to named ideal attendees on LinkedIn, Instagram, Facebook or wherever they spend their day. Ads and content can work, but they depend on strangers noticing you. A direct message with a specific reason and a date usually gets an answer within days.
Why is nobody registering for my event?
Usually 1 of 3 reasons: the wrong people saw it, too few people saw it, or the page doesn't say clearly who it's for and why it's worth the time. Run the math: if you need 86 registrations and only reached a few hundred people through 2 posts, the volume was never there. Fix the promise first, then the volume.
How do you get people to attend a free event?
Expect more no-shows: PheedLoop's data shows a median of about 28% for free events against 17% for paid. Register about 40% more people than you have seats, check in personally 2 days before and offer an easy swap to a later date if they can't make it. For small, high-value rooms, a refundable deposit is worth testing.
Is direct outreach better than social media posts for filling an event?
For a business event with a specific audience, yes. Posts reach whoever the feed decides to show them to, while a direct invitation reaches the exact person you picked and gives them a reason to answer. Use both: your posts make you look credible when someone checks your profile after your message.
