Acceptable Use Policy

Effective July 8, 2026 · Operated by Deep Thought Technologies Inc.

In plain English

Send only things you're legally allowed to mail, to a recipient who has a reason to receive them. No illegal content, no threats or harassment, no unsolicited bulk mail, no infringing other people's work, no fraud or impersonation.

We screen every order with automated systems and human review before it's mailed. We can refuse, hold, or cancel any job, and our print partner can reject anything USPS won't carry. If we cancel your order we refund it and email you — and if you think we got it wrong, you can appeal to a person. Break these rules on purpose and we may suspend or close your account.

1. Who you can mail to

You can use Printwhisk to mail a letter to yourself or to another recipient. You are responsible for the content you send and for having a legitimate reason to send it to that address. Printwhisk is not a tool for harassment, for unsolicited or bulk mailings, for impersonating someone, or for using an address you have no legitimate reason to mail to. We may review letters before they are mailed and may refuse or cancel any that break these rules.

2. What you may not print or mail

You agree not to use the service for, or to submit, any of the following:

Anything illegal under federal, state, or local law.
Threats, harassment, stalking, or content intended to intimidate or harm.
Material that infringes someone else's copyright, trademark, or other intellectual property, or that you do not have the right to reproduce.
Fraud, forgery, counterfeit documents, or anything designed to deceive (including impersonation and fake official notices).
Unsolicited commercial mail, chain letters, bulk mailings, or mail to a recipient who has not agreed to hear from you.
Content that is non-mailable under USPS rules, or that exposes our staff or print partner to legal risk.
Any attempt to disrupt, overload, reverse-engineer, or gain unauthorized access to the service.

3. USPS and print-partner rules

Your letter is printed and mailed by our fulfillment partner and delivered by USPS. They may refuse content that violates the USPS Domestic Mail Manual or their own policies. If a job is rejected for these reasons we treat it as a fulfillment failure and credit you back, but we will not re-attempt content that cannot lawfully be mailed.

4. File rules

Documents must be valid PDFs.
A single letter may be up to 60 pages.
We print in black & white only.
Larger documents may be split into multiple letters or mailed as one large envelope, as described on the pricing page.

5. How we review orders

Every order is screened by automated systems and may also be reviewed by a person before it is printed. Our automated review looks for signals of the prohibited uses above — for example deceptive, fraudulent, or forged documents, impersonation, and unsolicited or bulk mail. An order that is flagged is held and is not mailed while we review it.

We may refuse, hold, cancel, or remove any job, and suspend or terminate any account, if we believe these rules are being broken — with or without notice, and at our discretion. When we cancel an order in review, we refund what you paid for it and email you to explain. Serious or illegal misuse may be reported to the appropriate authorities.

Think we got it wrong? Automated review is not perfect. If your order was cancelled and you believe it was a mistake, reply to the cancellation email or write to appeals@printwhisk.com, and a person will review your appeal.

6. Reporting abuse

If you believe the service is being misused, or received mail through us that you believe violates this policy, contact abuse@printwhisk.com. Copyright complaints have a dedicated process on our DMCA page.
