You don't need a printer. You don't need stamps. You don't need to find a post office.

Your letter is printed, inserted into an envelope, stamped, and handed to USPS or your chosen carrier the next business day. No account required.
How to Mail a Letter Online — 5 Simple Steps
- Prepare your document. Format your letter as a PDF. You can mail anything that fits on standard letter paper — personal correspondence, invoices, legal notices, contracts, tax forms, and more.
- Upload your PDF at www.mailform.io. Drag and drop your file, or pull it directly from Google Drive, Dropbox, or another cloud storage service. No account needed to get started.
- Enter the recipient's address. Mailform uses USPS address verification to confirm the address is valid and deliverable before your letter goes out. International addresses are also supported.
- Enter your return address. This appears on the envelope and ensures undeliverable mail comes back to you.
- Choose your options and pay. Select printing format (single or double-sided, color or black-and-white), mail class, and any add-ons. Pay with credit card, PayPal, or Apple Pay. You'll receive an email confirmation immediately.
