Hello @felipeelia
Any update regarding this problem.

Thanks

I have an [email] field in my repeater and I needed to send a confirmation to each of those emails from Mail 2. If you have a similar situation, you can add the following code to your functions.php file
Be sure to review the comments to update the code where necessary.

// make sure plugin is active on site
if ( is_plugin_active( 'cf7-repeatable-fields/cf7-repeatable-fields.php' ) ) {
	
	/* Allows multiple email fields from the repeatable email field in form #78223 in Mail 2
	*/
	function fx_wpcf7_repeatable_recipient($mail2, $form) {
		// BE SURE TO UPDATE BELOW WITH YOUR OWN FORM ID
		if ( $form->id != 78223 ) return $mail2;
		$to = array();
		// I added some JS to prevent the user from adding more than 4 emails, but you can add more if you need
		if( isset( $_POST['email__1'] ) )
			$to[] = $_POST['email__1'];
		if( isset( $_POST['email__2'] ) )
			$to[] = $_POST['email__2'];
		if( isset( $_POST['email__3'] ) )
			$to[] = $_POST['email__3'];
		if( isset( $_POST['email__4'] ) )
			$to[] = $_POST['email__4'];

		$to = implode( ',', $to);
		$mail2['mail_2']['recipient'] = $to;
		
		return $mail2;
	}
	add_action( 'wpcf7_additional_mail', 'fx_wpcf7_repeatable_recipient', 99, 2);
}

Thanks for sharing your solution @chloemccarty !

This is great! @chloemccarty can you share the JS to prevent the user from adding more than X number of repeater fields as well?

Recently I had a similar scenario as @chloemccarty, where I need to send emails through Mail to multiple recipients. Also, I use repeatable [emails] field. Following the provided solution for Mail 2 and after modifying code to fit on the Mail form, I added the following code in the functions.php.

// make sure plugin is active on site
if ( is_plugin_active( 'cf7-repeatable-fields/cf7-repeatable-fields.php' ) ) {	
	// define the wpcf7_mail_components callback 
	function filter_wpcf7_mail_components( $components, $form, $instance ) { 
		// make filter magic happen here... 
                // BE SURE TO UPDATE BELOW WITH YOUR OWN FORM ID
		if ( $form->id != [FormID]) return $components;
		$to = array();		
		$i = 1;
		while( isset( $_POST['friend-email__'.$i] ) ) {
    		        if( isset( $_POST['friend-email__'.$i] ) ) {
				$to[] = $_POST['friend-email__'.$i];
				$i++;
			}
		}
		$to = implode(',', $to);
		$components['recipient'] = $to;
		return $components; 
	}; 

	// add the filter 
	add_filter( 'wpcf7_mail_components', 'filter_wpcf7_mail_components', 10, 3 ); 
}

@HristinaJ @chloemccarty Any idea how to get this working in the additional headers (Bcc) rather than just the To field?

[HristinaJ]

@n-mitchell I think it can be achieved using $components['additional-headers'] instead of $components['recipient'], but haven't tested it.

$components['additional_headers'] = "Bcc: $bcclist";

[n-mitchell]

@HristinaJ Thanks, got it working with this:

$components['additional_headers'] = "Bcc: $bcclist";

Are these solutions mentioned above still applicable to the latest version?
How are we able to send an email confirmation to repeated emails?

Are these solutions mentioned above still applicable to the latest version?

I have just tried @Hristinaj's with success (WP 6.7.1, CF7 6.0.3, CF7-RF 2.0.2).

Note that the FormID to customise within the code should be CF7's Form ID and not WP post type object's ID.

How are we able to send an email confirmation to repeated emails?

In CF7 form edition screen -> Email's tab, I filled the field "Additional headers" with:

Reply-To: [suscriber_email__1], [suscriber_email__2], [suscriber_email__3], [suscriber_email__4], [suscriber_email__5]

where suscriber_email relates to the name I gave to the repeatable CF7 field collecting the email address in the form, and __{number} to the five first occurrences of the repeatable field (empty occurrences are ignored as expected).

CF7 treats it as a configuration error, but submitting a test form proves that it works fine (confirmation emails well received).
