Thanks for your help.

I add this filter but i have also to change bp_send_email function in file /buddypress/bp-core/bp-core-functions.php. then it works.

Before:

$must_use_wpmail = apply_filters( 'bp_email_use_wp_mail', $wp_html_emails || ! $is_default_wpmail );

	if ( $must_use_wpmail ) {
		$to = $email->get( 'to' );

		return wp_mail(
			array_shift( $to )->get_address(),
			$email->get( 'subject', 'replace-tokens' ),
			$email->get( 'content_plaintext', 'replace-tokens' )
		);
	}

After:

$must_use_wpmail = apply_filters( 'bp_email_use_wp_mail', $wp_html_emails || ! $is_default_wpmail );

	if ( $must_use_wpmail ) {
		$to = $email->get( 'to' );

		return wp_mail(
			array_shift( $to )->get_address(),
			$email->get( 'subject', 'replace-tokens' ),
			$email->get_template( 'add-content' )
		);
	}

Is there any way to hook/override this “$email->get_template( ‘add-content’ )” keeping the plugin core unchanged?
