I have the bad habit of not putting a return address on my outgoing postcards and at this point I feel like it gets lost or it's not a priority to process. I tend to send anywhere from 20-100 postcards at a time, but from those I only get confirmation of about 10.

How do you mail postcards in bulk?
- drop it off at your nearest mailbox
- drop it off in the drop box inside the post office
- hand deliver it to a postal worker
- other?

This is nothing new and has happened for over a year. I just assume the person gets it and just doesn't let me know, which is fine but then I am left wondering if they did receive it or not.

Thanks peeps.
