Can't open my Feathery form

Hello there! I was trying to submit my form and testing it but found out I’m always getting an error. Every single time I try to open it it says: Activate your form by inviting a verified business email to your Feathery account.

I was trying to search for an answer here but nothing seems to be working. Is someone able to explain to me what’s going on? Thanks in advance!

You need to have a business email in your Feathery account to take your forms live. You’ve likely signed up for an account with a personal email (e.g. @gmail), but you’ll need to invite another email from a non-personal email domain and have them verify ownership of that email by logging in with the invite
