It depends on how your posts or pages are set up. Are these user profile pages? If so, you may be able to use one of the pre-written special mail tags. There is one available for the post-author email. So, on the form settings page in the Mail TO: field put [_post_author_email] and as long as each post or page is for that specific user, then it should send it to that user’s email. Here are all the special mail tags built into the plugin – https://contactform7.com/2009/12/25/special-mail-tags/
If these aren’t user profiles and the posts or pages aren’t created by different authors, then you’ve got just a little bit of custom coding to do. My first step would be to see if I can utilize custom fields for the recipient email address.
Try this…
In /wp-content/plugins/contact-form-7/modules/special-mail-tags.php add this line of code just before the return $output on line 69:
elseif ( '_post_recipient' == $name )
$output = get_post_meta($post->ID, 'recipient', true);
Then go to one of your posts where you will have these custom forms and add a custom field with the name “recipient” and enter the recipient’s email for the value.
Lastly, go to your form settings that is inserted within your post and add [_post_recipient] in the TO field.
Now test it and see if it will work. Doing it this way will allow you to use only one form for all 200 posts, but you will need to specify the recipient email in the custom fields of each post.
Good Luck!
