Contact form 7 vs Custom Fields

hey im working on school project and each page /post has different responder this mean contact form must be flexible….
normally each email directly goes to the email address site admin or what we filled up in form settings
but I like to add custom field and change the responder automatically in each page / post

/////////////
example
jessie post a article about frogs
but her friend Tom need to access her and ask the question over the contact form
so
To : <?php get_field(‘Current_email’); ?>
name : Tom xxx
Question : xxxx xxxx xxxx
////////////

how can I do this ?
