Please note that your developer has to make sure they are using SMTP authentication in backend coding. That means
1. You need to create an email id on your shared hosting ac on our server and then use the full email id as username and password of that email id in backend code. You need to use SMTP hostname as localhost and files/folders shall be uploaded on the server before you try to run it.
2. Use the help of google.com to get sample code for any PHP / asp.net coding examples of how to have SMTP authentication-based email generation from codes.
If you do not use SMTP auth of any email id locally created the form may not work and throw errors.
