Import Limits

Each calendar has a limit on how many new people you can add to its contacts. Most hosts never reach it — it’s there to keep Luma a safe place, not to get in your way.

What Counts Toward Your Import Limit

Your import limit counts the new people you add to your calendar.

Inviting someone uses your import limit. Anyone you invite to an event — by email or from your contacts — gets added to your calendar’s contacts, just like a spreadsheet import. Invites and imports draw from the same limit.

Inviting or adding someone again is free. If a person is already in your contacts — because you invited or imported them before — adding them again doesn’t use any of your limit. You only use it up on people who are new to your calendar.

Your limit opens back up as people engage. When someone you added registers for one of your events or follows your calendar, they stop counting toward your import limit — so you get that room back to add more. And anyone who discovers you and signs up on their own never counted in the first place, so your organic audience can grow without limit.

Removing contacts doesn’t free up your limit. The limit counts everyone you’ve added who hasn’t engaged, and removing someone doesn’t change that — so you can’t clear out old contacts to make room for new ones. Engagement is the only thing that gives room back.

Requesting a Higher Limit

If you reach your import limit, you can ask us to raise it:

1. On web, go to your calendar’s People tab and click Add People.
2. Upload a CSV or enter the people you want to add. If you enter more people than your calendar has room for, a “This list may be over your import limit” banner appears with a Request Increase button — click it to open the request form. The banner doesn’t appear just from opening the import screen.
3. Tell us how many more people you need to add and why, then submit the request.
4. We’ll review it and email you. Once approved, the higher limit applies to that calendar right away.

The Invite Guests window on an event shows a notice when you’re over your weekly invite limit, but it has no Request Increase button. To request a higher import limit, use People > Add People on the calendar.

Importing Large Files

Each import can be up to about 10MB. If a big spreadsheet fails with a size error, delete every column except email (and name, if you want it), or split the file and import the parts one at a time with the same tag. People already in your contacts don’t use your import limit, so it’s fine if the parts overlap.

Import Limits vs. Send Limits

Your import limit is about how many people you can add to your contacts. It’s different from your weekly send limit — how many invites and newsletters you can send out. If you’re trying to message people rather than add them, see that article.
