Email address forms go to

Hey guys,

Im having trouble getting my form to work, Ive filled in “mail” section the email address I want all the emails to go to but there are errors then and the form won’t work returning “Failed to send your message. Please try later or contact the administrator by another method.” when I try to send a test.

Ive searched for where to set the email and it doesn’t return anything related to this issue, Im sure its just a set up issue but there are no documentation to explain where the email goes is there?
