How to Drive Better Webinar Success with SMS Marketing

73% of B2B marketers are the best way to drive leads to their business. If you’re an online marketer, especially an online marketer at a B2B business, then you have likely been involved with webinars at some point in your career.

The problems people face when trying to use webinars are well known: How do you make sure people actually show up? How do you know if they found it valuable? How do you then convert someone from being a webinar attendee to a customer?

There are plenty of resources out there about how to solve those problems. But one resource that is still generally under-utilized is SMS marketing. In this post, we’ll talk about five ways to use SMS to promote your webinar marketing campaigns.

How to Promote Your Webinar Marketing Campaigns

Reminders

The most basic way to use SMS is to send out reminders just before the webinar goes live. After all, most of us have fairly busy schedules and it can be easy to forget about a webinar we signed up for. So a quick text five minutes before the webinar starts can be a really helpful reminder to attendees as well as being a great, simple way to boost attendance.

Reminders have another value as well. There are several reasons why people might no-show for your webinars after signing up. One is what we already described—they’re busy and forgot about it. If that’s the biggest problem you have, then SMS should help to solve it.

But what if SMS doesn’t solve it? You send out reminder alerts. People open them. But your attendance numbers don’t move at all.

This is still helpful. Why?

Because now you know something other than busyness is keeping people from attending after they have already signed up.

The most obvious culprit is that when it actually came time to commit that hour or hour and a half, the attendees were not convinced that the content was worth their time. You caught their attention initially. That’s why they signed up. But now they’re not convinced.

If that is happening to you, then you know that you need to improve the hook for the webinar to improve attendance. So even when an SMS reminder campaign “fails” it succeeds because it gives you more information about why your attendees aren’t actually showing up.

Marketing

In addition to using it to send out reminders, you can actually use SMS as a marketing tool to promote webinars to your audience.

Thanks for signing up for our newsletter last week. I wanted to invite you to my live webinar called 'How to Double Your Website’s Conversion Rates.' Go here to register (link).

We will not take too much time explaining how this works because you would use SMS to do this in the same way you would email. The difference is simply that SMS messages will be shorter and more targeted.

But it is the same concept: You have a list of contacts. Based on their behavior, you are sending those contacts certain messages asking them to take further steps with your business. Almost everyone does this on email. Very few do it with texting.

Given that texting open rates are 4xs better on average than email, that doesn’t make a lot of sense. Texting, just as much as email, should be part of your marketing toolbox.

Feedback

Another way you can use texting as part of your SMS promotion strategy is by using SMS to ask for feedback on previous webinars. This can be a great way to evaluate how your webinars are currently performing, ways to improve them, etc.

“

Thank you for attending my webinar. In your opinion, what would make my next webinar better?

Obviously there are other ways of evaluating how engaging a webinar is. You can look at how long the average person watches. You can look at how many people show up that signed up. You can look at what attendees do after attending. But in each of those cases, you’re looking at a behavior and then trying to identify the motivation for the behavior.

In contrast, by simply asking for feedback, you’re letting people tell you what they thought. This can give you another type of data that you otherwise will not have when assessing future webinar plans.

Share Replays

One of the obvious benefits with webinars, of course, is that they can be recorded and viewed later. But for the same reason that it is easy to forget about the live webinar it is also easy to forget about the webinar replay.

That said, every replay can potentially be a significant asset for your marketing team. You can—and should—be using the content in the webinar in other venues, of course. You can turn it into a blog post or a case study. But you can also continue to benefit from the actual webinar recording by sharing the recording with your SMS list.

In particular, we recommend sending your replay link to people who signed up to attend the webinar but then did not actually come. They have already communicated interest in the content so you have strong reason to think they’d want to see the recording.

Mobile Surveys

Finally, we already mentioned the option of using SMS messages to ask for open-ended feedback from webinar attendees.

But you can also create simple surveys and send those out to segments from your SMS marketing list. For example, if you had a large number of no-shows on your last webinar, you might send out a survey question like this:

“

Why did you not attend this week’s webinar? - Reply A for 'too busy,' B for 'I forgot,' C for 'I’m not interested in the topic,' D for 'Other'

Or, you might reframe the question so that it will not put people on the defensive:

“

What would make you more likely to attend future webinars? - Reply 1 for 'Host them at a different time of day,' 2 for 'Host them on a different day of the week,' 3 for 'Cover a different topic'

The idea is that you are re-establishing contact with the person and giving them a chance to share what they think. People are usually happy to share their opinions and by doing that here you are, potentially, reengaging a lead who had gone cold after skipping the recent webinar.

Webinar SMS Workflow (Step-by-Step)

Here's how a webinar SMS workflow works, step by step.

1) Collect SMS-ready opt-ins at registration

• Add a phone field + checkbox to your webinar form (Zoom, GoToWebinar, or landing page).
• Make it clear attendees will get 1–3 helpful reminders + a replay link.

Average webinar live show-up rates hover ~29-31%, so every incremental nudge counts. Recent benchmark sets from 500k+ registrants (2025) and a broader B2B study (2024) support this baseline.

2) Instantly confirm via SMS

Auto-send: “Thanks for registering, [First Name]! Save this link: [link]. Reply Q for questions.”

Create a segment for the webinar.

If you're using Zoom or GoTo as your webinar provider, you can set all of this up automatically directly within the Mobile Text Alerts dashboard.

Otherwise, you can create general workflows in the dashboard interface or use Zapier or the SMS API to automate the process.

3) Send a reminder 12-24 hours ahead of time

Text #1 (value hook): 1–2 bullets about what they'll get.

Again, this can be automated within the online Mobile Text Alerts dashboard or via API.

4) Final reminders 1 hour and 5 minutes ahead of time.

Examples:

“

See you in 1 hour for the webinar! Join link: [link]

“

We're live in 5 minutes! Join here: [link]

“Just-in-time” reminders can do a lot to lift show-ups; one of our specific tests yielded a 6x attendance increases when adding SMS reminders.

5) Post-event follow-ups at 1 hour and 24 hours

According to Contrast, 47% of webinar views are on demand rather than live. In light of that, nudging replays can help expand total reach beyond the live hour.

Alternatively, you can nudge registrants who did attend live to take the next action in your funnel.

Webinar SMS Success Stories

Here are results some people have seen from implementing SMS flows for their webinars:

• An attendance increase of 11% to 68% (6x!) for our own webinar
• A 91% webinar view rate (between live and on-demand)
• An increased click-through rate over email for accessing the webinar, from 1.9% to 12.4%

Conclusion

Ultimately, webinar success is about the quality of the webinar itself. SMS marketing is a tool to drive traffic to your webinars and make it easier for people to both follow your work and share their thoughts on it. But you can have all the marketing techniques in the world, if you don’t have the right product and the right fit, you’re going to struggle.

The goal here, then, is not to present a kind of silver bullet for webinar success. Rather, it’s to suggest some relatively simple ways that webinar hosts can use SMS to increase viewership and receive valuable feedback.

FAQ

Q1) Will SMS really move my webinar attendance needle?

Yes! Since SMS have such high read rates and view rates, it's much more likely that people will see your reminders to join the webinar or watch the replay. One of our tests saw an attendance increase of 11% to 68%! (See "Success Stories" above.)

Q2) How many texts should I send?

You can test the cadence to see what works best for you.

One cadence that would be a good starting point is:

• 1 confirmation text
• 1 text 24 hours before
• 1 text 1 hour before
• 1 text 5 minutes before
• 1 text 1 hour after

Q3) What about compliance/opt-outs?

Mobile Text Alerts handles most of the compliance concerns for you. Collect explicit consent at registration and make sure people know they can "Reply STOP to opt out." (When they reply STOP they will be automatically removed from the texts.

Q4) Does personalization matter?

Yes. Tailoring reminders and CTAs to interest signals (registration answers, link clicks, past attendance) could help you see more attendees and better conversions.

Q5) What if most of my audience watches replays?

That’s normal! many programs see a large portion of views on-demand. You can send segmented replay links with a short takeaway and optional next step (demo, guide).
