How to import a guest list from a spreadsheet

Where your list actually lives
A ticketing export, a shared spreadsheet, a reply thread you have been keeping score in, or all three. Real lists are assembled from several places and almost never arrive in one tidy format.
The mess is normal
Commas inside quoted company names. Phone numbers written five different ways. Blank rows, a header that is not the first line, the same person twice with two addresses. This is what an honest guest list looks like and an import that assumes otherwise will fail on the first one.
Paste it and check the result
Intro Connect takes a pasted spreadsheet, a comma separated file, or an export from a ticketing tool, and handles quoted fields and untidy phone numbers rather than refusing them. Read what came back before you send anything, because a wrong address is a guest who never hears from you.
Invitations from the same list
Once the list is in, each guest can be sent a join link without you assembling a separate mail merge. The list you already had becomes the event, which is the point: importing should be the end of the admin, not the middle of it.
