Start with your files
Upload a PDF, Word file, images, a package, or a CSV list. You split a document into mail pieces by page count or by text. The AI proposes where to split, and you confirm.
Features
All the essentials. None of the mailroom.
USMail.ai is an AI print-to-mail platform that gives you the essentials of sending real mail without a mailroom. You upload your document, review a proof and the full price, and approve. Nothing prints until you do. We print it, add postage and hand it to USPS. Letters starting at $1.15, postage included. For a one-page, single-sided, black-and-white First-Class letter.

Essentials
What does USMail.ai do for each job?
Check the addresses
You supply every address. The AI never invents a recipient. Scan addresses from your files, import a CSV, or add them by hand. You choose how to handle duplicates before you approve.
Leave the prep to us
We handle the printing, envelopes, and postage. Black and white or color. Single or double sided. Photo or document finish.
Approve with confidence
You review the details and price before anything is mailed. Every job needs a human approval. The AI never approves mail.
Follow your mail
Qualifying First-Class tracing shows available scans. Priority Mail and Certified Mail include USPS tracking.
Mail on your schedule
Same-day when the job qualifies (1:00 PM CT). Default next business day (10:00 PM CT). Schedule up to 60 days. Monday to Friday.
Your envelope. Your brand.
Can my envelopes carry my logo?
Custom envelopes with your logo are included. The envelope must be approved before use, which can take 1–2 business days. Same-day still has to qualify on a plain #10 envelope.
Letters starting at $1.15, postage included. For a one-page, single-sided, black-and-white First-Class letter.
How do tracing and tracking differ?
First-Class tracing
Qualifying First-Class tracing shows available scans; it is not legal proof of mailing or delivery confirmation.
IMb tracing on qualifying domestic First-Class letters and First-Class postcards shows USPS scans through "out for delivery." Not Marketing Mail.
Priority and Certified tracking
Priority Mail and Certified Mail include USPS tracking. Certified tracking can reach Delivered. Not the same as First-Class tracing.
What else is in the product?
File and batch options
PDF, Word, images, packages, CSV lists and other formats the app accepts. You split a document into mail pieces by page count or by text. The AI proposes where to split, and you confirm. You choose how to handle duplicate names and addresses before you approve. Statements and invoices run as uploaded files and lists. You approve each job.
Printing and envelopes
Black and white or color. Single or double sided. Photo or document finish. Custom envelopes with your logo are included. The envelope must be approved before use, which can take 1–2 business days. Same-day still has to qualify on a plain #10 envelope. The colorful envelope below is a sample. Not every envelope gets a stamp.
Address checks
You supply every address; the AI never proposes one. CASS runs on the job. NCOA is available when set up on your account. National Change of Address checks USPS move files before print. It is not a delivery-day promise.
Cutoffs and scheduling
Same-day when the job qualifies (1:00 PM CT). Default next business day (10:00 PM CT). Schedule up to 60 days. Monday to Friday. Same-day still has to qualify on a plain #10 envelope. Certified is not available for postcards and is never same-day.
Approval and job storage
Every job needs a human approval. An approved job can be unapproved until its mail date, and unapproving puts the money back on your meter. You can cancel a mailing before production begins. Jobs are kept until the job's expunge date. 30 days is only the default. You pay as you go per mailing, or from an optional prepaid meter balance.
Optional agent access (MCP)
Available now on the app. Same production path. A human sets a postage grant. The sender supplies every address. AI never invents recipients or approves mail.
Features FAQ
Is tracing included on First-Class?
Yes. IMb tracing is included on qualifying domestic First-Class letters and postcards. It shows USPS scans through out for delivery. It is not Marketing Mail and not legal proof.
Is tracking included on Priority or Certified Mail?
Yes. Both include USPS tracking. It is not an add-on. Certified tracking can reach Delivered.
Can I use a custom envelope with my logo?
Yes. Custom envelopes with your logo are included. They must be approved before use and can take 1–2 business days. Same-day jobs still have to qualify on a plain #10 envelope.
What is included per mail piece?

What is Posty AI?
Posty AI chats with you at every step and can propose setup. It never proposes addresses and never approves. A human approves, either on the app or by setting a postage grant.
When does my letter go to USPS?
By default, letters you approve before 10 p.m. CT are handed to USPS the next business day (Monday to Friday). USPS delivery times vary. USPS handles delivery from there. There are no contracts, subscriptions or setup fees.
