Picture this. You spent three weeks building your webinar. The landing page converts at 40%. You have 2,000 registrants. You go live and 280 people show up. You do the math and realize your show-up rate is 14%. Every slide, every story, every carefully constructed objection handler: seen by less than 1 in 7 people who signed up to be there.

I’ve built and optimized 114 webinars over the last 10 years. I’ve helped generate over $100M in webinar sales, from scaling Mindvalley from $25M to $75M in annual revenue, to pushing Tony Robbins’ RMT program from a 100% ROAS to 388%. And if there’s one thing I see course creators underinvest in consistently it’s not the pitch, it’s not the content, it’s not even the offer. It’s getting people to actually show up.

A 15% show-up rate is not unusual. But 15% is also not acceptable. The difference between 15% and 30% is not marginal it’s the difference between a webinar that barely breaks even and one that funds your next quarter. You don’t need more registrants. You need more of the people who already said yes to actually walk through the door.

Email helps. But email alone is no longer enough. Inboxes are crowded, promotions folders are hungry, and the average person receives over 100 emails a day. There’s a channel that cuts through all of that. It fits in a pocket. It buzzes. It gets read. It’s SMS. And most course creators are leaving it completely on the table.

This article is about one thing: how to use webinar SMS reminders to push your show-up rate from 15% to 30%. I’ll give you the exact timing, the exact message structure, and the sequence that works.

But if you’re here because people are registering and not showing up, you’re in exactly the right place.

Why Show-Up Rate Is Your Real Conversion Problem

Most people optimizing their webinar funnels obsess over conversion rate. That makes sense but it’s the wrong place to start. Conversion rate is what happens after someone shows up. Show-up rate determines how many people ever get the chance to convert.

Here’s the math in plain terms. Say you need 50 sales to hit your revenue goal. Your webinar converts at 8% for a warm audience. That means you need 625 live attendees to hear the pitch. If your show-up rate is 15%, you need 4,167 registrants to get 625 people live. If your show-up rate is 30%, you need 2,083. Same goal. Same conversion rate. Half the registrants and half the ad spend.

The benchmark I work toward is 25% for live webinars. Some well-optimized funnels hit 35% to 40%. But I see show-up rates of 10% to 15% regularly, especially from creators who treat registration as the finish line instead of the starting line. The moment someone registers, the real work begins.

Why SMS Works When Email Doesn’t (Anymore)

Email open rates average around 20% for marketing sends. SMS open rates average around 98%. That number is not a typo.

When a text message arrives, most people read it within three minutes. When a marketing email arrives, most people don’t read it at all. The inbox is a place people manage. The phone is a place people live. SMS puts your reminder directly into the second category.

It’s not about email being dead. Email is still the most profitable channel I know I’d challenge anyone to show me otherwise. But email reminders for a live event face a specific problem: people register, get the confirmation email, read it, feel good about attending and then completely forget. Life gets in the way. By the time your reminder email arrives at 9am on the day of the webinar, it’s competing with 40 other unread messages.

A text message is different. It demands attention in a way email no longer does. Use that difference.

The 4-Message SMS Sequence (Exact Timing)

You don’t need to spam people into showing up. Four well-timed SMS messages is all it takes. Here’s the sequence.

Message 1: 24 Hours Before

This is your anchor reminder. People registered, possibly days ago. Life has happened since. This message is simply a reminder that tomorrow is the day and a reason to be excited about it.

Keep it warm and specific. Don’t just say “your webinar is tomorrow.” Tell them one thing they’ll get from showing up. Then give them the direct link. No friction. One tap, and they’re in the calendar.

Example: “Hey [Name] your spot at [Webinar Title] is confirmed for tomorrow at [Time]. You’ll discover [specific thing they’ll learn]. Here’s your link: [URL]”

Message 2: Morning Of (3 Hours Before If Evening)

This message builds anticipation. They woke up today with this event on the calendar. Reinforce that decision. Remind them why they signed up in the first place. One sentence on the promise. One sentence on the link.

Example: “Today’s the day, [Name]. [Webinar Title] starts at [Time] and I’m covering [specific outcome]. See you there: [URL]”

Message 3: 1 Hour Before

This is where people start making decisions. They’re finishing lunch. They’re wrapping up a call. They’re thinking about whether they’ll actually dial in. Your job is to make “yes” the obvious choice. Urgency is appropriate here not fake urgency, just the reality that it starts in 60 minutes.

Example: “[Name] we’re one hour away. [Webinar Title] starts at [Time]. Grab your spot: [URL]”

Message 4: 10–15 Minutes Before

This is the most important message in the sequence. Don’t skip it.

Ten minutes before start time, people are deciding in real time. They’re at their desk. They’re checking their phone. This message lands at exactly the right moment when showing up is still possible and the decision is live. Keep it ultra-short. No explanation needed. Just the facts.

Example: “Starting in 10 minutes, [Name]. Join now: [URL]”

That’s it. Short. Direct. The link is one tap away. People who were on the fence will click. People who forgot will click. That single message, sent at the right time, is often responsible for 20% to 30% of your total live attendee count.

What Makes a Good Webinar SMS (And What Kills It)

A few rules that matter:

Keep it under 160 characters when you can. Long SMS messages get split into multiple texts on some carriers. Short messages feel personal. Long messages feel like marketing.

Use their first name. Every major SMS tool allows personalization tokens. Use them. A message that starts with the person’s name feels different from a broadcast. It doesn’t need to be elaborate just present.

Include the join link in every message. Not just in message four. Every single message. Every unnecessary step between “I’ll attend” and “I’m on the webinar” is a place where someone drops off.

Write like a human, not a brand. SMS is an intimate channel. People use it with their families. The moment you sound like a press release, you lose the medium. Write like you’re texting a colleague who you genuinely want to show up.

Don’t add emojis to compensate for weak copy. The copy should do the work.

SMS Plus Email: The Full Show-Up Stack

SMS reminders are not a replacement for email. They’re a layer on top of it. The people who hit 35% to 40% show-up rates consistently are running both a structured pre-webinar email sequence that primes interest and builds anticipation, combined with SMS that catches people in the moments between inbox checks.

Think of it this way: email builds the relationship between registration and the event. SMS closes the gap in the final 24 hours. Both are doing different jobs. Neither works as well without the other.

For the email side of the stack, The Pre-Webinar Email Sequence That Doubles Your Show-Up Rate covers the full structure what to send, when to send it, and exactly how to frame each message to build momentum into your live event.

The Tools You Need

Most major marketing automation platforms now include SMS natively or through integrations ActiveCampaign, HubSpot, HighLevel, Kajabi. If you’re running ads through ClickFunnels or a similar funnel builder, SMS integrations are built in. Dedicated SMS platforms like Attentive or SimpleTexting work well if you want more control over compliance and delivery.

One thing that matters: make sure you’re collecting phone numbers on your registration page. Optional but highly encouraged. Offer an explicit incentive for opting in to SMS reminders something like “Get a text reminder 10 minutes before we go live” converts well. People want the reminder. They just don’t always know to ask for it.

The One Metric to Watch

Track your show-up rate by traffic source. Not all registrants behave the same. Cold traffic registrants show up less than warm list registrants. Paid traffic registrants show up less than organic. Knowing where your show-up rate is lowest tells you where to focus: more aggressive SMS sequences, stronger pre-event email nurturing, or better qualification on the registration page itself.

Growth hacking is a process: hypothesize, test, measure, and systematize. Your show-up rate is a metric you can move with the right interventions. SMS reminders are one of the clearest and fastest levers you have.

Start Simple, Then Optimize

You don’t need a perfect sequence before your next webinar. You need a functioning one. Set up the four-message framework, collect phone numbers on your registration page, and send the 10-minute message at minimum. That alone will move your numbers.

First you nail it, then you scale it. Get the basics running, see what your show-up rate does, then optimize message timing, copy, and targeting from there.

A show-up rate of 30% is achievable. The people who hit it aren’t doing anything magic. They’re just doing the work consistently, systematically, with the right tools in place. That’s all this is. Now go run your next webinar like a marketer, not like a teacher hoping people remember to show up.
