Email to Postal Mail

"There are three reasons why you may want to send emails as paper letters using snail mail:

1. Some of your relatives live in remote villages where they don't have computers let alone access to Internet.

2. Your grandparents know computers but they'll probably feel more happy if you could send them emails and photographs in paper form that they can read in the lawn outside.

3. You are trying to reach someone who already gets a few hundred email messages per day. Your email may get lost in the clutter but if you take the snail mail approach, chances are high that he or she will at least read your message if not respond to it."
