Message the Sandboxx team ASAP if you need one of your letters deleted.
Please be sure to specify which letter you need deleted. (We’d hate to delete the wrong letter by mistake.) One of the best ways to specify which letter you are talking about is by sending us the 16 digit letter ID.
Before reaching out, please make sure you actually need your letter deleted. If there is an issue with the address, we can fix that. We can also put your letter On Hold - that will keep it from going out with the next shipment but won’t delete it. If you want to resend any of the message, we suggest you copy the text before reaching out to us. We work quickly and wouldn’t want you to have to type out everything all over again.
It is not always possible to delete your letter after it’s been sent. We print and send letters throughout the day. Due to the high volume of letters printed each day- we cannot guarantee that your letter can be pulled. The highest likelihood of finding and deleting your letter is before you get your “Letter has been Sent” notification. After that point, it’s been processed/printed and sorted, and might not be able to be located without holding up other letter sender’s letters.
