Send Bulk Meeting Invites - Easy Steps

Have you tried to Send Bulk Meeting Invites to over 100 people to an event using Google or Outlook calendar? At first, it seems simple. You add emails one by one, click send, and boom, done. But then… error messages pop up. Attendees can see each other’s emails. And worse, Google blocks you after some invites without giving you the exact limit. 

It feels frustrating, right? You waste hours breaking your list into small groups, sending the same invite again and again. By the time you’re done, half your audience has already missed it.

Google & Outlook Calendar Limitations

Google and Outlook calendars work fine for small meetings, but if you need to send bulk meeting invites to hundreds or even thousands of attendees, they quickly reach their limits. Invites may fail, guest lists can become visible, and managing large groups can become confusing and stressful. For big events, you need a smarter, more reliable way to send bulk meeting invites effortlessly.

Google Calendar Limitations

  • Max 200 guests per invite
  • Invites may land in spam if too many are sent at once
  • No calendar personalization

Outlook Calendar Limitations

  • Frequent blocking of large sends
  • Privacy risk: guests can see each other’s emails
  • Slows down with long guest lists
