way too many nonrelated emails or advertisement emails. $4 to send a letter is ridiculous
Update-the app shows the letter has not been delivered. Someone from Sandboxx did reach out to me quickly and shared a notification that the letter was delivered when promised. A glitch caused the problem It sounds great, but the delivery is no faster than regular mail. I sent a letter on June 30th, well before the cut-off to be delivered before the July 4th holiday. It's July 4th, and the letter hasn't been delivered to the base yet. If you say you're going to provide a service, then do it.
letters take more than 3 days, they do not arrive when they tell you
Only selling letters in packs of 3 or more and also "expiring" letters in 6 months is a wild money grab. I need 1 letter. 1. At the absolute bare minimum the extra 2 you're forcing me to buy (that I don't want or need) should never expire so I can send one the next time I need one. But of course, you'd rather me have to buy 3 more then, of which I would still only need 1.
my letters are un-delivered
The app seems a little predatory on pricing. The interface on the app doesn't work right, so use the website. It claims on the app that you get a free letter, but you don't. I wrote out the whole thing for the first free letter, saved it, then was prompted to buy a letter package. I purchased the $15/5 letters, and then poof! Letter gone. After searching the app to no avail, I got on the computer and logged in. Luckily my letter was there! And no free letters when people use the link you share.
Loved using Sandboxx. It was so easy to use corresponding with my son. Would highly recommend it!!
won't send my letter.
I love this app. seriously, a life saver. takes away the stress of wondering if my letters were delivered. I get to send pictures also I know that with sand box they send the stationary needed with my letter so I can get a letter back from my baby. in a stressful time, this app is there for you and your loved one.
This app is amazing and great for all friends &family. They really went above and beyond for our troops and recruits. This is a blessing for us with busy minds. VERY INFORMATIVE AND EASY TO USE
