Stamps for Good, by M&C Saatchi Abel
M&C Saatchi Abel has teamed up with marketing company RocketSeed on a new initiative called Stamps for Good.
The campaign allows people to include a virtual stamp featuring a miniature artwork in their emails.
The series of ten stamps are linked to ten different charities, including the Animal Anti-Cruelty League and Reach for a Dream.
For more information on how to subscribe to the initiative, visit the Stamps for Good website.
