Hi @prithsr

Ok, if I’ve understood right, here’s how I think I’d possibly approach it:

I’d use the acf/save_post function:

add_action('acf/save_post', 'my_acf_save_post');
function my_acf_save_post( $post_id ) {

    // Get newly saved values.
    $values = get_fields( $post_id );

    // Get post author ID
    $author_id = get_post_field ('post_author', $post_id);

    // Add a custom field to the user 
    update_user_meta( $author_id, 'some_custom_field', '1' );

}

You could then query the users via a php file you run on cron:

	#query our users
	$args  = array(
		'role__in'     	=> array('editor'),
		'role__not_in' 	=> array('administrator'),
		'exclude'      	=> array(1),	
        'meta_query'        => array(
			array(
				'key'       => 'some_custom_field',
				'value'     => 1
			)
        )					
	);	
	$user_query = new WP_User_Query( $args );
	$user = get_userdata( $user->ID );

You could wrap the whole query in a date check to compare the current date with the date set by the user

If the date matches and the query returns a result, you can then reset the custom meta for the user/author:

    // Reset custom field to the user 
    update_user_meta( $user->ID, 'some_custom_field', '0' );

So roughly the email function could look like:

###################################################
# Send Emails When custom_post_typePublished
###################################################
add_action( 'transition_post_status', 'send_email_notification', 10, 3 );
function send_email_notification( $new_status, $old_status, $post ) {

	if ( 'publish' !== $new_status or 'publish' === $old_status || 'custom_post_type' !== get_post_type( $post ) )
	return;
	
	if ( defined( 'DOING_AUTOSAVE' ) && DOING_AUTOSAVE )
	return;	
	
	#get the post ID, we can now use this on both publish and update functions
	$post_id = $post->ID;	
	
	#add date check here
	$todays_date = '';
	$specific_date  = '';
	if ($todays_date == $specific_date ) {

		#query our users
		$args  = array(
			'role__in'     	=> array('subscriber'),
			'role__not_in' 	=> array('administrator'),
			'exclude'      	=> array(1),	
			'meta_query'        => array(
				array(
					'key'       => 'some_custom_field', //only want to send to specific users
					'value'     => '1'
				)
			)					
		);	
		$user_query = new WP_User_Query( $args );
		
		#get our email data if we have any results
		if ( ! empty( $user_query->get_results() ) ) {
			#create an array
			$email_recipients = array();
			foreach ( $user_query->get_results() as $user ) {
				$user = get_userdata( $user->ID );
					
				$email_recipients[] = array(
					'forename'	=> $user->first_name,
					'email'		=> $user->user_email
				);	
				
				update_user_meta( $user->ID, 'some_custom_field', '0' ); //reset the custom meta until front end form retriggers
			}
		}
		
		#filter duplicates (may not need this)
		#$email_recipients = array_unique($email_recipients);	
		
		#proceed with the email if we have a result
		if ($email_recipients) {
	
			foreach ($email_recipients as $recipients) {			
	
				$to			= $recipients['email'];
				$subject	= "Email Subject Goes Here";
				$message	= "<p>Dear {$recipients['forename']}</p>";
	
				#create the headers
				$headers = array(
					'Content-Type: text/html; charset=UTF-8',
					#'Cc:' . '[email protected]',
					#'Bcc:' . '[email protected]',				
					'From: '.get_option( 'blogname' ).' <[email protected]>'
				);	
				#send the email
				wp_mail ($to, $subject, $message, $headers);					
			}
		}	
	
	}

}

It may require some spit and polish but should be a rough starting point I hope!?

Cheers
