Terms of Service

Last updated: November 3, 2026

1. About these terms

These terms are an agreement between you and Think On Labs LLC, an Oregon company ("we", "us"), which runs Incredible Letters at incredibleletters.com. By using the site you agree to them. If you don't agree, please don't use it. Our Privacy Policy explains how we handle your information.

2. What Incredible Letters does

Incredible Letters helps you write a heartfelt letter to someone you care about, for any occasion. You tell us about them and choose a style, an AI writing helper drafts a letter, and you edit it until it says what you mean. You can then download or print it, save it to your account, or pay us to print and mail it.

3. Who can use it

You must be at least 18 to use Incredible Letters. Letters are often written to children, but they are written by adults.

You can write a letter without an account. To save letters, pay, have a letter mailed, or write more than a few letters, you need an account. Keep access to your email and any sign-in provider you use secure, because anyone who can open your sign-in links can use your account. You can delete your account at any time on the Account page.

4. Your letters

You are the author of your letter. The AI is a writing helper: letters are written with Incredible Letters, not by it. What it drafts can be wrong, generic, or not quite right for the person, so read and edit every letter before you send it. You are responsible for what your letter says.

You own your letters. You give us permission to process, store and print them only as needed to provide the service to you, for example to draft, check, save, display, print and mail them. We don't use your letters to train AI models unless you choose to (below), and we don't publish them.

If you turn on "Help improve Incredible Letters" (it is off unless you do), you also give us permission to keep, read and use the letters you write, save or change while it is on, as our Privacy Policy describes, to make our letters better, including testing our letter writing and training an AI model of our own. You can turn it off on your Account page at any time, and we then delete what we kept for it.

We check letters and the details you enter with automated safety tools. We may decline to write, save or mail a letter that fails those checks.

5. Sending letters responsibly

A letter from Incredible Letters should be a welcome surprise. When you send or mail a letter, you promise that:

  • You know the recipient, and you have no reason to think they don't want to hear from you.
  • Sending it doesn't break a court order, protective order, restraining order, custody arrangement or any other no-contact rule.
  • It isn't meant to harass, threaten, frighten, deceive or embarrass anyone.
  • The sender name on it, on the letter and on the envelope, is your real name, or one the recipient will recognize as you.
  • It doesn't include anything you don't have the right to share, such as someone else's private information or copyrighted material.

We limit how many letters can be mailed to the same address. We may refuse, cancel or refund any letter, and suspend any account, if we believe these promises have been broken.

6. Stopping letters

Anyone can ask us to stop mailing or emailing them at incredibleletters.com/stop, and every mailed letter and email from us says how. A parent or guardian can do this for a child. Once an address or email is on our do-not-contact list, we won't send it new letters or emails, and we won't tell a sender why a letter couldn't be sent. A letter already handed to our print partner before the request may still arrive, because we can't recall it.

7. Things you may not do

  • Use Incredible Letters for anything unlawful, harmful, threatening, abusive, harassing, defamatory or hateful.
  • Impersonate someone else.
  • Try to get around our usage limits, safety checks or the do-not-contact list.
  • Use bots or scripts to write letters in bulk, copy the site, or access it in ways other than through the pages we provide.
  • Interfere with the site's security, or upload viruses or other malicious code.
  • Infringe anyone's intellectual property.

8. Payments

Writing a letter is free. Downloadable letters with our designs are pay what you want: any amount from $1 unlocks most designs for your account, and some special designs unlock when what you have paid in total is more than an amount we show you. What you pay to mail a letter while signed in counts toward both. A pay-what-you-want payment buys access to those designs. It is not a charitable donation. Mailing a letter costs the price shown before you pay, which includes printing, envelope and postage. Coupons and offers apply only as stated on them.

Payments are processed by Stripe. Prices can change, but a change never affects something you have already paid for.

Your unlock. What you unlock belongs to the account you paid from. It does not expire, and it can't be moved to another account. Paying to mail a letter while you are signed in also unlocks the first level of designs on that account. If a payment is refunded or charged back, the refunded part stops counting toward your unlock, and the unlock ends if what is left isn't enough for it. While a chargeback is open, that payment pauses your unlock; if the dispute is decided in our favor, the unlock comes back.

Prepaid letters. When we offer letter packs, you can buy several mailed letters at once. They belong to the account you bought them from, they don't expire, and they can't be moved to another account or exchanged for cash. One is used each time you mail a letter, and it comes back if that letter isn't mailed. Contact us to refund the letters you haven't used. A refund or chargeback of a pack takes back the letters it paid for, and an open chargeback pauses them.

Refunds. If we decide we can't mail a letter you paid for, for example because the address can't receive it, the recipient opted out, it fails our safety checks, or our print partner rejects it, we refund the full amount automatically. If a letter is delayed while we sort out a problem on our side, we either send it or refund it. If something else goes wrong, contact us and we will make it right.

9. Mailed letters

Mailed letters are printed and posted by our print-and-mail partners through the postal service. We check that each address looks deliverable, but we can't guarantee delivery or a delivery date, and the dates we show are estimates. We don't track delivery, and we never tell senders whether a letter arrived or was opened. You are responsible for entering the right address.

The envelope carries the name you give for it (or only our name, if you leave it blank or we have to switch this off) with our return address. Letters that can't be delivered come back to us. We destroy them and we don't forward them or tell you. A letter that comes back because of the address you entered isn't refunded.

10. Our content

The site, its designs, templates, artwork, logos and software belong to us or our licensors. You may use the designs in letters you make here for personal, non-commercial purposes. You may not resell them or use them to build another service. If you send us feedback or ideas, we may use them without owing you anything.

11. Disclaimers

Incredible Letters is provided "as is" and "as available", without warranties of any kind, express or implied, including warranties of merchantability, fitness for a particular purpose and non-infringement. We don't promise the site will always be available or free of errors, or that any letter the AI drafts will be accurate or suit your purpose.

12. Limitation of liability

To the fullest extent the law allows, we are not liable for any indirect, incidental, special, consequential or punitive damages, or for lost profits, data, use or goodwill, arising from your use of Incredible Letters, even if we were told they were possible. Our total liability for all claims about the service is limited to the greater of $100 or what you paid us in the 12 months before the claim.

13. Indemnification

You agree to defend and indemnify Think On Labs LLC and its owners, employees and agents against claims, losses and costs (including reasonable attorneys' fees) that come from letters you send, your use of the service, or your breaking these terms or anyone else's rights.

14. Ending your use

You can stop using Incredible Letters and delete your account at any time. We may suspend or end your access if you break these terms or to protect someone from harm. Sections that by their nature should last, such as ownership, disclaimers, limits of liability and indemnification, continue after that.

15. Governing law and disputes

These terms are governed by the laws of the State of Oregon, without regard to its conflict of law rules. Any dispute about these terms or the service will be settled by binding arbitration in Portland, Oregon, under the rules of the American Arbitration Association, and judgment on the award may be entered in any court with jurisdiction. Any claim must be brought within one year after it arose.

16. Changes to these terms

When we change these terms we update the date at the top. If a change is significant, we will tell you by email or on the site before it takes effect. Using the site after that means you accept the new terms.

17. Other terms

These terms, with the Privacy Policy, are the whole agreement between you and us about Incredible Letters. If any part is found unenforceable, the rest still applies. Not enforcing a part right away doesn't mean we give it up. You may not transfer these terms to someone else; we may transfer them along with the service.
