Send First-Class Mail online
Mailing a letter should not mean a printer, a book of stamps, and a mailbox. MatterSnail sends USPS First-Class Mail from the browser: upload the letter, add the recipients, and it is printed, stuffed, and handed to USPS the same business day, from one letter to a hundred.
How it works
Upload the letter
Attach your letter as a PDF, or several: up to 20 documents per mailing, in the order they should appear in the envelope. No printer, no envelopes, no stamps.
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 an individually addressed and printed letter.
USPS takes it the same day
Submit before the 12:50 p.m. Pacific cutoff and the mailing is printed, stuffed, and handed to USPS the same business day.
Everything the mailing needs
Printed the way you want
Single-sided or double-sided, your choice. The first four sheets per recipient are included; longer letters add a small per-sheet printing fee.
A return envelope inside
Enclose a self-addressed envelope for any recipient, unstamped or prepaid with a one-, two-, or three-ounce stamp, so signed papers come straight back to you.
Certified when it matters
The same mailing can send one recipient First-Class and another Certified Mail with tracking and a Certificate of Acceptance, 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 First-Class is not enough
First-Class is the everyday workhorse, and it travels without a tracking number. When you need proof, send Certified Mail with per-recipient tracking and a Certificate of Acceptance. When you need speed, send Priority Mail and it typically arrives in 2 to 3 business days, tracking included.
