I order prints from them almost every month, I thought they were only deleting pictures if you didn't order something!?!?!?!
definitely contact them- i got that same email- never deleting files etc.
plus they say they back up their pictures and such- they might be able to recover your account. GL
Definitely contact them - I'm sure it was probably a glitch in their system and they'll be able to retrieve them for you.
That said, I still keep ALL of my photos on a cd as backup just in case Shutterfly ever crashes.
