How Bulk Calendar Invites Can Improve Webinar Attendance Rates

Webinars are one of the most powerful tools in a modern marketer’s playbook — but only if your audience actually shows up. Getting people to attend your online event depends heavily on one thing: getting your invite onto their calendar. That’s where bulk calendar invites come in.

With tools like Let’s Calendar (www.letscalendar.com), you can automatically send personalized, scalable calendar invitations directly to your audience’s preferred platforms — Google Calendar, Outlook, and Apple Calendar. In this blog, we’ll show you how bulk calendar invites can dramatically improve attendance for your webinars, how to implement them, and why Let’s Calendar is the best event invite app to do it.

The Problem with Traditional Email Invites

If you’ve been relying on email reminders alone, you’re already at a disadvantage. Traditional email invites:

• Often get buried under hundreds of other emails
  

• Don’t provide an easy way to add the event directly to a calendar
  

• Are easy to ignore or forget

The result? Lower attendance, despite all the effort you put into organizing the webinar. This is why you need an approach that ensures your event makes it onto your audience’s schedule — and stays there.

Calendar invites, especially when powered by an event invite app, are proven to increase webinar attendance. They’re harder to miss and come with reminders that help bring people in at the right time.

What Are Bulk Calendar Invites?

Bulk calendar invites are a way to send calendar events — not emails — directly to thousands (or even millions) of recipients with just a few clicks. Each invite contains the full webinar details, like date, time, meeting link, and agenda, and appears directly on the recipient’s calendar.

With bulk calendar invites for webinars, you:

• Reach your audience where they plan their time
  

• Ensure automated reminders go out pre-event
  

• Reduce no-shows and improve engagement

Whether you're running a small team webinar or a massive online conference, bulk meeting invites make it scalable.

With Let’s Calendar, You Can…

Let’s Calendar simplifies and supercharges the process of sending bulk calendar invites. Here’s what it helps you do:

• Send Mass Calendar Invites: Deliver calendar events to 10 or 10,000+ people instantly
  

• Personalize Invites: Add attendee names, breakout room links, local timezone adjustments, or custom messaging
  

• Track Engagement: See who accepted, declined, or hasn't responded — in real time
  

• Automate Your Workflows: Connect with CRMs, email marketing tools, and webinar platforms like Zoom or Webex

It also allows you to discreetly send 1:1 invites — crucial for high-touch events or CXO-level outreach.

How to Add Events to Different Calendar Platforms

With Let’s Calendar, your invites are compatible with every major calendar platform. Here’s how it works across systems:
