How about sending someone a postcard that has been created from your emails! Sounds like something that has been tried before, well you could be right there anyone remember snail mail by email? Well Postcardly is similar but the people behind this are in it for the long term, rather than just a project. Currently there is a free sign up etc, but this service is great for travellers who what to show off some images of their travels but are still able to connect to those who have no computer or internet connection.
According to the Postcardly website the process is simple and fast;
Postcardly turns your emails into real-life postcards, delivered by U.S. Mail. It’s especially great for staying in touch with older family members who don’t use computers. You can send postcards from your phone, your computer, or anywhere you have email. Just send an email with an attached photo the way you normally send an email: your photo will be on the front of the postcard, your words will go on the back.
