Sorry I have to join in - use snail mail and be sure you don't include your return address.
And, wear latex gloves and type it on an antique typewriter that you can smash with a sledge hammer in the dark of night - and mail it from five counties over without a stamp, with the return address to whom you want it sent and addressed to a bogus business - and don't forget to NOT lick the envelope. You should be fine.
