Let’s leave snail mail in the dust…

Now Available: Instant Delivery to Select Prisons

We are excited to announce that LetterQuick is now able to print your letters instantly and directly inside two California State Prisons. This service is now available at California State Prison, Centinela and Calipatria State Prison.

We couldn’t be more happy to share this news with you. Since 2012, LetterQuick has been using the U.S. Postal Service to send your letters. While we believe thus far our methods have made LetterQuick the fastest and most convenient way for you to write to inmates, standard “snail mail” comes with limitations that we will now be able to bypass at these two prisons – making it possible for us to introduce a new golden standard. We are hopeful that correctional facilities throughout the country will continue to embrace technology as a means to connect inmates with their friends and family. We applaud Calipatria and Centinela State Prisons for leading the way in California.

The vast majority of prisons continue to allow only snail mail. We can’t guarantee we will be able to expand our instant delivery service to additional prisons, but we’re working hard on your behalf to explore the possibility. If you’d like to help, click here to tell us why the prison you write to should modernize its mail system – we’ll share your stories with prison officials as we continue to press forward.



We’re a California-based business with the ability to send your letters quickly - read our How It Works page to find out more! We’re working hard to modernize the delivery of mail to inmates in California.


LetterQuick is an affordable alternative to sending mail the traditional way. No need to purchase stamps, envelopes and other accessories – just send your letter like an email!


Follow our guidance and we’ll help your letter breeze through the mail sorting and screening process. We’ll credit your account if you encounter any difficulties, so your experience is risk-free.


We can ship photographs to your recipient, as well as postcards and envelopes so they’re able to write back! We’ll even scan and email you the responses to postcards you purchase.
