If you want to use postcards to promote a service at an event by sending a batch of cards to the address where the event is taking place or send to your organisation so you can take the cards to events, the current limited option of sending individual cards to an address doesn't enable this. It would be really useful if there was an option to send a specified number of cards all to one address e.g. inside a single addressed envelope. Ideally the cards themselves would have no delivery address printed on them as this would be confusing for anyone picking one up at an event stall etc.
