So, I had a letter waiting in my mailbox today from a good friend of mine. It was a small 3-3/8″ x 6″ manila mailer with a small lump in it. It has a regular letter stamp on it. Inside was a 3-1/8″ x 5-3/4″ gray piece of paper. This piece of paper had a slit in one end, and through the slit was a red ribbon with a tiny key on the end of it. Printed on the bottom of the paper was a web address and password.
I went to the website and was presented with a blank page that asked for the password. I logged in and read a letter from my friend, inviting me to visit, and showing photos of their lives together.
It created a lot of mystery and was really fun. Cheap too. I could imagine adapting this to business.
