5,000 contacts can be uploaded at a time.
If you have an Excel spreadsheet with up to 5000 contacts, that can be uploaded.
If you have an Excel spreadsheet with more than 5000 contacts, it needs to be split into two or more files and uploaded separately.
The total number of contacts is unlimited.
Please note that the uploader will not accept any html tags or text such as <html> etc in any of the contact columns.

🎓 Recap
You can upload up to 5,000 contacts per file, but there's no limit on the total number of contacts you can store in your On The Stage account. To import more than 5,000 entries at once, simply split them into multiple upload files, and make sure none contain any HTML tags. intercom.help+5intercom.help+5help.instantly.ai+5bulkemailsetup.com
