Email notification not sending after deleting entry with hook

Hi,

I'm deleting form records after submission using gform_post_submission and have also tried gform_after_submission. Deleting the record works great, but I no longer get the email notification - if I comment out deleting the entry from the database I get the email no problem. It looks like these hooks are before the user email notifications are sent out - is there a way to manually force-send the email notification or use the hook differently to make sure notifications go out?

add_action('gform_post_submission_1', 'process_order', 10, 2);

function process_order($entry, $form)
{
	// do stuff
	remove_form_entry($entry['id']);
}

function remove_form_entry($entryId)
{
	global $wpdb;

	$lead_id = $entryId;
	$lead_table = RGFormsModel::get_lead_table_name();
	$lead_notes_table = RGFormsModel::get_lead_notes_table_name();
	$lead_detail_table = RGFormsModel::get_lead_details_table_name();
	$lead_detail_long_table = RGFormsModel::get_lead_details_long_table_name();

	//Delete from detail long
	$sql = $wpdb->prepare(" DELETE FROM $lead_detail_long_table
		WHERE lead_detail_id IN(
			SELECT id FROM $lead_detail_table WHERE lead_id=%d
		)", $lead_id);
	$wpdb->query($sql);

	//Delete from lead details
	$sql = $wpdb->prepare("DELETE FROM $lead_detail_table WHERE lead_id=%d", $lead_id);
	$wpdb->query($sql);

	//Delete from lead notes
	$sql = $wpdb->prepare("DELETE FROM $lead_notes_table WHERE lead_id=%d", $lead_id);
	$wpdb->query($sql);

	//Delete from lead
	$sql = $wpdb->prepare("DELETE FROM $lead_table WHERE id=%d", $lead_id);
	$wpdb->query($sql);
}
