LetterTrack revenue, team size, customer count, churn, and more in 2026.

LetterTrack was developed to provide online sellers(like those selling products on eBay, Etsy, and Amazon) and other online retailers with the ability to track lightweight, inexpensive items. As long as the mailpiece is 3.5oz or less and can be mailed in an envelope or bubble mailer, it can be mailed and tracked through LetterTrack. Our web based application, LetterTrack Pro, prints directly to envelopes or address labels and adds an intelligent mail barcode(also known as USPS Informed Visibility® Mail Tracking) above the address which provides the buyer and seller with real time tracking emails each time the mailpiece is scanned at a USPS facility. The final scan each mailpiece receives is at the local post office of the destination city. When a mailpiece reaches the destination post office to be placed on a USPS postal truck for delivery, the mailpiece is marked as Out for Delivery. It only costs between $.18 and $.32 per transaction to send a mailpiece via LetterTrack Pro. The seller simply applies regular postage to the envelope, flat, or bubble mailer they are shipping and places the item in their mailbox. We provide 5 free transactions to anyone who registers so they can try LetterTrack at no obligation.
