Contact Form Issue

Hi i am using Zerif Lite theme for my website – wantsolution.com

I am facing the problem of recieving form submissions on my mail. i entered my email address in general and contact us option, i even changed the $emailTo value to my email address instead of calling value from theme.

There is no mail in my inbox, spam or elsewhere. the message of successfully sent appears but no mail is recieved.

i have two forms on my website, one is zerif-lite inbuilt and other is using contact form 7 plugin.

i have been using other theme before for same website and at that time my contact form 7 plugin was working. but now both the forms are not working.

Kindly help me out with the same ASAP.

Thank You.
