Hi Sherry!
Any information that falls under the "Business Information" or "Submitted by" section of an application is considered personal information, and as such can only be changed by the applicant who submitted the application. If the email that was input on the application was input incorrectly, you would need to reach out to the person/company that submitted the application and have them log into their account. They would be able to correct the information on their end by editing their application.
If they need any help in editing the information, please have them reach out to support@eventeny.com, and we will be happy to assist them with it.
