Terms of Service
Effective: May 1, 2026
These terms are a binding contract between you and Hartkraft, Inc. ("we," "us," "our"), the operator of mailall.us. You accept them by checking the acceptance box when you sign up, or by continuing to use the service after being notified of an update. If you don't accept them, don't use the service.
Heads up. Section 14 requires most disputes to be resolved by individual arbitration and waives your right to participate in a class action. You can opt out of the arbitration agreement within 30 days of signup; see that section for how.
1. The Service
mailall.us is an email group forwarding service. You create a group address, invite members who confirm their membership, and email sent to the group address is forwarded to each confirmed member. We don't retain message content except briefly and only as needed to deliver or retry; see the Privacy Policy for the details.
2. Delivery Modes
Each group can be configured with one of two delivery modes:
- Reliable (default): failed deliveries are retried automatically. In rare failure scenarios, encrypted message data may be held for up to 24 hours before automatic deletion.
- Private: each message is sent once with no retries, and we do not write message content to any queue or persistent storage at the application layer. If delivery fails, the message is lost. Note: infrastructure providers may briefly buffer messages during outages outside our control; see the Privacy Policy.
You can change delivery mode at any time; the change takes effect on the next incoming message.
3. Eligibility
You must be at least 13 years old to use mailall.us. If you're in the European Economic Area or the UK, you must be at least 16. If we learn that an account was created by someone below the minimum age, we will delete it.
4. Your Account
You are responsible for all activity under your account. You agree to keep your registered email address current. Legal and service notices sent to that address are effective when sent, whether or not you actually read them.
Each person or entity may maintain only one free account, including only one free trial. Creating additional accounts through email aliases, secondary addresses, or any other identifier to obtain additional trials is a violation of these terms, and we may suspend or terminate any such accounts without notice. At our discretion we may extend or re-grant a trial, but this is never guaranteed.
5. Member Consent
Anyone can be invited to a group, but no one is added to forwarding until they explicitly confirm by clicking a link we send them. Group owners must use the service only for messages members would reasonably expect to receive, and may not send marketing email, unsolicited promotions, or spam through a group.
6. Acceptable Use
You agree not to use mailall.us to:
- Send unsolicited bulk email, marketing email to people who didn't consent, or any message prohibited by CAN-SPAM or similar laws.
- Distribute malware, phishing, or fraudulent content.
- Harass, threaten, impersonate, or defame others.
- Violate any applicable law, regulation, or third-party right (including intellectual property and privacy).
- Scrape, reverse-engineer, probe, or attempt to circumvent rate limits, authentication, or other protections (except with our prior written authorization for security research).
- Interfere with the service or with other users.
We are the sole judge of whether these terms have been violated, and may suspend or terminate accounts without prior notice.
7. Free Trial
New accounts receive a 30-day trial with Basic-tier service levels (2 groups, 10 members per group, 500 messages/month). After the trial expires, delivery is reduced to group owners only for one week. After that grace period, all inbound mail is rejected. You may add a payment method at any time during or after the trial to continue service.
8. Paid Plans and Billing
Paid subscriptions are billed monthly or annually via Stripe. Prices are shown on our website. We may change prices with at least 30 days' notice; for existing subscribers, a price change takes effect at the start of the next billing period after the notice. If you don't accept a new price, you can cancel before renewal.
You may cancel at any time. Cancellation takes effect at the end of the current billing period. If your account has a credit balance of $1.00 or more at the time of cancellation (for example, from a prior downgrade), that balance is refunded automatically. No other refunds are provided for partial periods.
Message packs are one-time purchases that add credits to your account. Credits never expire, are only consumed when your monthly plan quota is exceeded, and carry across plan changes. Message pack purchases are non-refundable. If you are in the EU or UK, by completing a message pack purchase you consent to immediate delivery of the digital product and acknowledge you waive the 14-day withdrawal right under applicable consumer law.
9. Termination
Either party may terminate these terms at any time. You can close your account from inside the app. We may close or suspend your account for violating these terms, for non-payment, or if we decide to stop offering the service (either to you specifically or in general).
On termination: your groups stop forwarding; your personal data is deleted under the schedule in the Privacy Policy; any unused prepaid subscription balance over $1.00 is refunded automatically; message pack credits are forfeited.
Sections that by their nature should survive, including Acceptable Use, the "As Is" Disclaimer, Limitation of Liability, Indemnification, Arbitration and Class Action Waiver, and Governing Law, survive termination.
10. Service Changes
We may change, add, or remove features at any time. If a change materially reduces the service for an active paying subscriber, we will give at least 30 days' notice and, on request made within that notice period, a pro-rata refund of any prepaid amount for the affected period. Otherwise the service is provided on an evolving basis.
11. "As Is" Disclaimer
THE SERVICE IS PROVIDED "AS IS" AND "AS AVAILABLE," WITHOUT WARRANTIES OF ANY KIND, EXPRESS OR IMPLIED, INCLUDING THE IMPLIED WARRANTIES OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, TITLE, AND NON-INFRINGEMENT. WE DO NOT WARRANT THAT THE SERVICE WILL BE UNINTERRUPTED OR ERROR-FREE, OR THAT ANY GIVEN MESSAGE WILL BE DELIVERED. Groups using Private delivery mode accept a higher risk of message loss in exchange for stronger privacy guarantees.
12. Limitation of Liability
TO THE MAXIMUM EXTENT PERMITTED BY LAW, HARTKRAFT, INC. IS NOT LIABLE FOR ANY INDIRECT, INCIDENTAL, SPECIAL, CONSEQUENTIAL, OR PUNITIVE DAMAGES ARISING FROM YOUR USE OF THE SERVICE. OUR TOTAL LIABILITY FOR ANY CLAIM IS CAPPED AT THE GREATER OF (A) ONE HUNDRED U.S. DOLLARS OR (B) THE AMOUNT YOU PAID US IN THE 12 MONTHS BEFORE THE CLAIM.
13. Indemnification
You agree to defend, indemnify, and hold harmless Hartkraft, Inc. and its officers, directors, and employees from any claim, loss, damage, or cost (including reasonable legal fees) arising out of your content, your use of the service, your violation of these terms, or your violation of any law or third-party right.
14. Arbitration and Class Action Waiver
You and Hartkraft, Inc. agree that any dispute arising out of or relating to these terms or the service will be resolved by individual, binding arbitration administered by the American Arbitration Association under its Consumer Arbitration Rules. The arbitration will take place in Jefferson County, Colorado, or by remote proceeding. Judgment on the award may be entered in any court of competent jurisdiction.
YOU AND WE BOTH WAIVE ANY RIGHT TO A JURY TRIAL AND ANY RIGHT TO BRING OR PARTICIPATE IN A CLASS, COLLECTIVE, OR REPRESENTATIVE ACTION. If this class-action waiver is found unenforceable for a particular claim, that claim must be brought in court under Section 16, but the rest of this Section 14 still applies to the rest of the dispute.
You may opt out of this arbitration agreement by sending an email from the email address on your mailall.us account (the one you signed up with, which is not itself an @mailall.us address) to arbitration-opt-out@mailall.us within 30 days of creating your account. Accepting subsequent revisions of these terms does not reset this window — it runs from your account creation date only. The email body may include any statement you wish; what matters is that the message is authenticated (SPF and DKIM pass) as coming from the email address associated with your account. We record these opt-outs automatically and preserve the message for our records. If you cannot send from your account email, or your opt-out falls outside the 30-day window, write to legal@mailall.us instead and we will review your request manually. Opting out won't affect any other part of these terms.
This section does not prevent either of us from seeking injunctive relief in court to protect intellectual property rights or stop ongoing abuse.
15. Privacy
Your use of mailall.us is also governed by our Privacy Policy.
16. Governing Law and Venue
These terms are governed by the laws of the State of Colorado, without regard to its conflict-of-law rules. For any dispute not subject to arbitration under Section 14, you and we consent to the exclusive jurisdiction and venue of the state and federal courts located in Jefferson County, Colorado.
17. Force Majeure
Neither party is liable for delay or failure to perform caused by events beyond reasonable control, including outages at infrastructure providers, internet failures, natural disasters, labor disputes, or government action.
18. Changes to These Terms
We may update these terms from time to time. For material changes, we will notify you by email to your registered address at least 30 days before they take effect, and we may require you to accept the new terms again before continuing to use the service. Non-material changes (typos, clarifications, updated contact details) take effect on posting.
19. General
These terms and the Privacy Policy are the entire agreement between you and us about mailall.us. If a court finds any part unenforceable, the rest still applies. Not enforcing a provision once doesn't waive our right to enforce it later. We may assign these terms in connection with a merger, acquisition, or sale of assets; you may not assign them without our written consent.
