Hello dhruti,
Firstly check is there any mail functionality is availbale on your server. If it's there then please check you got emails in your spam box.
If you still not getting emails then please check have you write any email id in AI Contact Form setting page. If you have write email id at that place then you received emails notification on that id and if you haven't write any email id at that place then email notification goes to WordPress general setting email id.
if you have still any query regarding this then please feel free to tell us.
Thanks & Regards,
August Infotech
