I already read other post where they were asking the same:
I must say that the solution didn't work for me. The contact-form keeps sending the emails to the email address set on Contact Form 7 configuration.
This is what i put on my single.php file:
<?php echo do_shortcode( '[contact-form-7 id="5" title="Form World Unite" destination-email="'.get_field( 'email' ).'"]' ); ?>
What could be wrong?
