Security review? We never store card numbers.

By the USMail.ai team, more than 50 years of combined expertise in printing and mailing

Direct answer: Teams evaluating USMail.ai, including builders connecting over MCP, get password-protected accounts, human approval before production, HTTPS on the site and app, and a payment gateway that holds card numbers. Job files and recipient lists are purged on the job's expunge date, and USMail.ai doesn't claim certifications it hasn't earned.

USMail.ai runs production mail through app.usmail.ai. This marketing site is www.usmail.ai.

What security practices are live today?

Account authentication. Jobs don't produce until a human approves them and they are paid for.
Human approval before production. You review on-screen proofs. We don't routinely screen your content. An approved job can be unapproved until its mail date. Unapproving puts the money back on your meter, not back on your card.
Payment. Card numbers are handled by the payment gateway. USMail.ai never stores card numbers.
Your data. Job files and recipient lists are purged on the job's expunge date. 30 days is only the default.
HTTPS. HTTPS on www and the app. This site sends HSTS, CSP, X-Content-Type-Options and frame protections. The app refuses framing.
Passwords. We will never ask for your password in an unsolicited call or email. Sign out when you finish, especially on a shared computer.
Uploads. Upload through the app, not email. Restrict portal access to people who should send mail, and remove access when someone leaves.
MCP. Tied to your account, with no anonymous mailing. Agents sign in over OAuth; there are no standalone keys.
Mail ops. 888-667-5322 / 316-247-5322 / info@usmail.ai.

How does USMail.ai handle your data?

We act as a conduit for print and mail. Lists and documents are processed to produce the job you approved, not for other marketing. We may disclose information to USPS or law enforcement when required or as described in the Privacy Policy and Terms. Deeper environment detail is available under NDA through a security questionnaire for qualified buyers.

What stays on the job?

You upload documents and lists. USMail.ai is an AI print-to-mail platform: You upload. You approve. We produce. The AI suggests setup; it never suggests addresses. We check every address before mailing, and the AI never suggests an address; every address comes from you. USMail.ai is not USPS. A human approves, either on the app or by setting postage grant for an agent. We print, insert, add postage and hand the pieces to USPS. Approving a job is not an endorsement of the words.

MCP uses the same account. Agents prepare jobs. A human sets postage grant, capped or uncapped, or reviews and does Pay & Approve on the app. Agents don't run card deposits. See MCP docs, Features and how it works.

What will USMail.ai not claim?

A live SOC 2 Type II (or other) certification, unless we publish a real report.
Any regulatory or industry compliance program that hasn't been confirmed in writing. If your process has specific data-handling requirements, raise them with mail ops in writing and confirm them with your counsel.
That we read every mail piece, or that approving a job means we endorse the content.
That USMail.ai is the U.S. Postal Service or a virtual mailbox, or that we control USPS delivery after handoff.

What does a mailing cost, and when does it go out?

Letters starting at $1.15, postage included. For a one-page, single-sided, black-and-white First-Class letter.

By default, letters you approve before 10 p.m. CT are handed to USPS the next business day. USPS delivery times vary. There are no contracts, subscriptions or setup fees.
