Sincerely, the company behind Postagram, is launching a photobooth-like experience for iOS users called PopBooth today that sends consumers real photo strips in the mail.

The app is pretty self-explanatory: users snap four photos in quick succession on their iPhones or iPads, apply some filters and then they can share them with friends through Facebook or e-mail. Naturally, they can also send real photo strips to themselves or friends for $2.99 to anywhere in the world within two to five business days.

Sincerely is focused on creating inexpensive real-world mementos like photographs and cards. It’s one of the rare consumer-facing mobile businesses that does have a revenue model and isn’t a game. Consumers can buy credits for the app in increments from $2.99 to $627.90 for 250 credits

The team behind the company is experienced. Co-founder Matt Brezina was also behind enterprise e-mail company Xobni. The company hasn’t disclosed any funding.
