Send USPS Priority Mail online
When the filing is thick or the deadline is close, Priority Mail is the answer: typically 2 to 3 business days, tracking included. MatterSnail sends USPS Priority Mail from the browser: upload the documents, add the recipients, and the parcels are printed, packed, and handed to USPS the same business day.
How it works
Upload the documents
Attach up to 20 PDFs and 2,000 total pages, in the order they should arrive. Larger page counts simply move the parcel into a bigger Priority Mail size tier.
Add the recipients
One recipient or up to 100 in the same mailing, typed one at a time or pasted from a spreadsheet. Each person gets their own individually addressed parcel.
USPS takes it the same day
Submit before the 12:50 p.m. Pacific cutoff and the mailing is printed, packed, and handed to USPS the same business day. Delivery typically follows in 2 to 3 business days.
Everything the mailing needs
Tracking on every parcel
Every recipient gets an individual USPS tracking number, with each scan from acceptance to delivery kept with the mailing.
A signature when you need one
Choose Priority Mail with signature and USPS captures the recipient signature as an electronic return receipt, with a downloadable Certificate of Acceptance.
Certified and First-Class too
The same mailing can mix services across recipients: Priority to one party, Certified Mail or First-Class to another, chosen per recipient.
Your whole team
Invite your team to the firm account and anyone can prepare and send. The Free plan includes up to 3 users with no monthly fee.
When Priority is more than you need
For everyday letters, First-Class Mail costs less and typically arrives in 3 to 5 business days. When what you need is proof rather than speed, Certified Mail travels First-Class with per-recipient tracking and a Certificate of Acceptance.
