A ringing phone is harder to ignore than an email or Slack ping. DoNotify calls you when something needs attention on your WordPress site: a new WooCommerce order, a completed order, a failed payment, or a new booking (WooCommerce Bookings, Amelia), with an optional reminder call beforehand. Any plugin or theme can trigger a call with one line: do_action('donotify_call', 'New VIP lead'). Free on WordPress.org; calls need a DoNotify subscription.
