Freenom + Infinityfree (Email Trouble) Help

Hi Guys,

I’d like to ask for who has a site freenom domain hosted on infinityfree to help me out.
My webmail works fine, but I can’t to on my site using “contact form 7”.

Shall I add something on freenom dns? I can’t do nothing over there otherwise my site will be down. I just put ns1.epizy.com, ns2.epizy.com on name servers. If I change to put manually the site won’t work.
