Wix crm does not prevent duplicate email address being registered so to verify an email has not been previousy registered you have to create a seperate database containing all previous member email addresses (make sure you format them all the same i.e. all lower case). Then query that database to see if the new member email address has already been used, something like this…
wixData.query(“emailDatabase”) .eq(“userEmail”, $w(" #SignupEmailInput ").value) .limit(1) .find() .then( (results) => { let numberOfResults = results.totalCount; console.log(numberOfResults)
