How to add multiple attendees correctly

When 2sync creates a Google Calendar event from a Notion database, it expects each attendee to be passed as a separate list item.

If you enter all the email addresses in one Notion property separated by commas, Google Calendar receives only the first address and ignores the rest.

In your Notion Attendees (text) property, press Enter after each email so every address is on its own line. For example:

[email protected]
[email protected]
[email protected]
