Sending a calendar invitation to one person is easy. But what if you need to invite 100, 500, or thousands of people to the same webinar, meeting, conference, or event?
Adding every attendee manually can take a lot of time. This is where a bulk calendar invite platform can help.
Let’s Calendar is a platform designed to help businesses and event organizers send mass meeting invites, multiple calendar invites, and personalized calendar invitations at scale. It works with Google, Outlook, Microsoft 365, and Apple calendars.
Why send multiple calendar invites with a bulk calendar tool?
When you have a large attendee list, creating individual calendar invitations can quickly become repetitive.
For example, you may need to invite:
Webinar attendees
Conference participants
Clients for meetings
Sponsors and partners
Training participants
Employees for internal events
Customers for product demonstrations
Instead of entering every email address manually, Let’s Calendar allows you to create an event, upload your attendee list using CSV or XLSX, and send the invitations in bulk.
Send mass meeting invites with Let’s Calendar
If you are looking for a way to send mass meeting invites, Let’s Calendar provides a simple workflow:
Create Campaign → Add Contacts → Send Calendar Invites → Track RSVPs
You can upload your contact list and send personalized invitations to each recipient. The attendees do not need to see the complete list of people invited to the event.
This makes it useful when you want to send multiple calendar invites while keeping each invitation personal.
How to send bulk meeting invites in Gmail
If your team uses Gmail or Google Workspace, you may be searching for send bulk meeting invite in Gmail or send mass meeting invites in Gmail.
With Let’s Calendar, you can connect your Google account, create your event, upload your attendees, and send the invitations through your connected email account. Each person receives their own calendar invitation rather than seeing a shared list of recipients.
This makes bulk calendar invite in Gmail much easier than manually creating the same meeting invitation again and again.
Bulk calendar invites in Google Calendar
Google Calendar works well when you are inviting a small number of people. However, larger events can require a different workflow.
If you are searching for bulk calendar invites in Google, Let’s Calendar lets you upload a larger attendee list and create a campaign for the event.
The invitation can include the event date, time, meeting information, description, and relevant meeting links. Invitations can then be delivered to the attendees' calendars.
Send bulk calendar invites to Google, Outlook and Apple users
One useful feature is that your attendees do not all have to use the same calendar platform.
Let’s Calendar supports invitations for recipients using Google, Outlook, Microsoft 365, and Apple Calendar.
So, if your attendee list contains people using different calendar services, you can manage the invitation campaign from one place.
What makes Let’s Calendar useful for large events?
Let’s Calendar is more than a way to send a bulk calendar invite. It is designed to help manage the invitation process as well.
You can:
Import attendees using CSV or XLSX
Send personalized 1:1 calendar invitations
Send invitations in bulk
Schedule invitations for later
Add webinar or meeting information
Send event updates or cancellations
Track RSVP responses
Connect Google Workspace or Microsoft 365
Use integrations such as Zoom and Zapier for supported workflows
This can save considerable time for teams that regularly organize meetings, webinars, conferences, and other events.
Is Let’s Calendar right for your use case?
If you only need to invite two or three people, your regular Google Calendar or Outlook calendar may be enough.
But if you regularly need to send bulk meeting invites, send multiple calendar invites, or manage invitations for hundreds or thousands of attendees, a dedicated bulk calendar invitation platform can make the process much easier.
With Let’s Calendar, you can create your event once, upload your attendee list, send the invitations, and manage responses from one platform.
