A webinar registrant joins with fifteen minutes until showtime. Webinar.net has their email, but you don't know their phone number. An SMS sent five minutes before the event starts drives attendance and engagement far more than an email reminder. Mobile Message sends an SMS through Zapier when a new registrant signs up, confirming their spot and including the start time and join link. Your registration flow moves from passive confirmation to active engagement. Attendees show up.

SMS confirmations for webinars are proven attendance drivers. Registrants get a text immediately upon signing up, then a reminder text minutes before the event starts. Your audience walk-in rate improves, and no-shows drop significantly. The psychology is simple: a text on someone's phone feels more urgent than an email in a folder.

For webinar hosts managing audience size and engagement, this shift from email to SMS can increase attendance by up to 40 percent. A registrant who receives an SMS reminder minutes before start time is far more likely to join on time. Webinar.net provides the registration, Mobile Message delivers the attendance.
