For one day only, every Sincerely user can send ONE FREE CARD with any of our Ship partner apps on your iPhone or iPad. Sincerely Ship partners are apps that have integrated our Sincerely Ship API so that users can send a postcard from their iPhone or iPad. We have been honored to partner with such amazing apps over the last year and want to thank you for helping us make the world just a little more thoughtful.

Here’s how it works:

• On Tuesday July 17, 2012 12am (PST), every Sincerely account will automatically be given credits to purchase and send a postcard. The credits will show up in your account and will disappear at 11:59pm (PST).
• #FreeCardDay is only for participating Sincerely Ship partners, which can be found here and are listed below. It does not apply to Postagram or Sincerely Ink.
• We have a limit of 50,000 cards.  One card will be allowed per user.  Once that limit is crossed, the promotion will end.
