Adding addresses.
You can add recipients addresses directly onto your app when creating a postcard but you can also add them in bulk at Sincerely's website - here's how to do it . .
After you have entered your billing information into the Sincerely system on the Cartolina Postale app, you can go to and click on the 'my account' button, top right. There you'll find a history of all your postcards. Click 'edit address book' - there you'll see a place to manually fill in addresses or you can import addresses in bulk from Gmail, Outlook, Mac Addressbook etc. Very useful when you want to send 1 postcard design to lots of different people!
