Wire Business Terms

Last updated: October 17, 2026

Draft prepared with AI assistance. It has not yet been reviewed by a licensed attorney, and nothing here is legal advice to you or to any customer. It is meant to describe the rules of the paid business version of Xatheryn Wire in plain but binding language.

Wire Business is not open for sign-up yet. These terms apply to a business plan only once you subscribe to one. Until then, the free personal service is covered by the Terms of Service, which do not allow business use.

1. Who these terms are between

Wire Business (the "Business Service") is the paid version of Xatheryn Wire at mail.xatheryn.com, operated by Xatheryn LLC, a North Carolina limited liability company ("Xatheryn," "we," "us"). These Business Terms are a binding agreement between Xatheryn LLC and the business or person who subscribes (the "Customer," "you"). "The Xatheryn Parties" means Xatheryn LLC and its members, managers, officers, employees and agents, and every protection in these terms for Xatheryn covers all of them. Each person who uses a mailbox under your subscription (a "User") must follow these terms and our Privacy Policy. You are responsible for your Users. If you accept these terms for a company, you promise you have the authority to bind it.

The Terms of Service and these Business Terms work together. If they disagree about something in a Business plan, these Business Terms win. Everything in the Terms of Service about scam protection, child safety, reports to law enforcement, and what may never be sent applies to the Business Service too.

2. Accounts, administrators and Users

Your subscription has one or more administrators you choose. Administrators can add, change and remove mailboxes, aliases and shared inboxes, set which Users may send, change your plan, and see billing. You are responsible for everything an administrator does and for keeping their sign-in secure.
Every User must be at least 18 years old, and must use their own mailbox. A mailbox is for one person unless it is set up as a shared inbox.
Users sign in the way Xatheryn Wire allows (a passkey, or a linked Xatheryn Connect account). If a User loses their sign-in, an administrator can start a reset for them. We can't read a User's mail to help.
You must give accurate business and billing details and keep them current.

3. Your domain and your addresses

You may add a domain you own or control. We will ask you to prove it by adding DNS records we give you. Don't add a domain you don't control.
You are responsible for your DNS records. Changing or removing them can stop mail from arriving or make it look forged. We are not responsible for mail lost or misdelivered because of your DNS settings.
Addresses at xatheryn.com that we give you stay ours and are licensed to you while you are subscribed. Addresses on your own domain are yours; if you leave, they stop working on our servers.
You may not use a domain to impersonate another company, person or government body.

4. What you may and may not send

Wire Business is for the everyday email of a business: conversation with customers, partners and staff, receipts, confirmations and the other messages people expect from you. Unlike the free service, business use is allowed.

You may not use the Business Service to:

send bulk marketing, newsletters or cold outreach in bulk. Wire Business is not a mass-mailing platform. Use a dedicated email-marketing service for that;
send to purchased, rented or scraped lists, or to anyone who has not agreed to hear from you where the law requires agreement;
send spam, phishing, scams, fraud, malware, extortion, or anything that tricks people into giving money, codes, passwords or personal information;
send mail without the sender details and opt-out the law requires. You must follow commercial email laws such as the CAN-SPAM Act, and the laws of every place you send to;
send content that harms or endangers a child, or that harasses or threatens anyone;
get around sending limits, scam protection, suspensions or blocks, or interfere with the service or other customers.

We may read a message or look at sending patterns only to the extent needed to enforce this section, to keep the service safe, and as the law requires.

5. Sending limits and fair use

Business plans include much higher sending limits than the free service, shown on your plan and in your administrator settings. Sending is fair use, not unlimited. We set limits per User and per customer, and may change them, to keep mail deliverable for everyone. A limit exists because other providers judge all of our mail by how our servers behave. We may slow, pause or block sending from a User, a domain or your whole subscription, immediately and without notice, if we see signs of spam, abuse, a compromised account or a sudden jump in volume, or while we look into a report. We will tell an administrator what happened as soon as we reasonably can.

We do not guarantee that any other provider will accept your mail, deliver it, or place it in an inbox rather than a spam folder. We do not control that.

6. Fees, billing and renewal

The price, billing period and number of Users are shown when you subscribe and in your billing settings. Prices are in U.S. dollars and do not include taxes, which we add where required.
Payment is taken through our payment provider. We do not store your full card number.
Subscriptions renew automatically for the same period until you cancel. Cancel in your billing settings before the renewal date to avoid the next charge.
Adding a User adds their charge for the rest of the period; removing a User lowers the next renewal.
Fees are not refundable, including for part of a period, except where the law requires, or where we choose to in writing. If we end your subscription without cause during a period you have paid for, we will refund the unused part.
If a payment fails we may retry, then pause sending and, if it stays unpaid, suspend the subscription. Your mail is not deleted for non-payment until the end of the export period in Section 10.
We may change prices for a future period by telling an administrator at least 30 days before it starts. If you don't agree, cancel before it starts.

7. Service level and support

We work to keep the Business Service running and will tell customers about planned downtime when we can. We do not promise a specific uptime and we do not offer service credits unless we agree to them in writing. Mail sent to you while we are down is generally held and retried by the sending provider, but we can't promise that every provider will retry. Support is by email at support@xatheryn.com, and we answer as quickly as we reasonably can.

8. Your content and our access to it

You own your mail and data. You give us permission to store, process, scan, deliver and show it only as needed to run the Business Service, including our scam and abuse checks, and as these terms and the Privacy Policy describe.
We don't sell your mail and never use it to choose ads. Your inbox shows no ads.
Administrators can see and manage mailbox settings and, if your plan includes shared inboxes, the mail in them. Administrators cannot read a User's private mailbox unless the plan expressly says so. If it ever does, we will tell Users first. You are responsible for telling your Users what your administrators can see and for having any permission your law requires.
Our own staff do not read your mail except to investigate a specific report of abuse or child-safety harm, to fix a problem you asked us to fix, or as the law requires.
You are the one responsible for any personal information of your own customers and staff that you put in the service, and for following the laws that apply to it. If you need a data-processing agreement for your own compliance, ask us at legal@xatheryn.com.

9. Security and your responsibilities

We use reasonable measures to protect your data, and run the service on servers we choose. No system is perfectly secure. You must keep sign-ins and recovery codes secure, remove Users who leave your organization promptly, tell us quickly if you think an account was misused, and keep your own copies of anything important. We are not a backup service.

10. Cancelling, suspension and your data afterwards

You can cancel at any time in your billing settings. The subscription then ends at the end of the period you paid for.
We may suspend or end a subscription, with or without notice, if you break these terms, if a payment fails, if your use puts our servers' reputation or other customers at risk, if the law requires, or if we decide to stop offering the Business Service. If we stop offering it for reasons other than your breach, we will give at least 60 days' notice and refund any prepaid unused fees.
Export window. After a subscription ends, administrators and Users can still sign in to download their mail for 30 days, and we will delete the mailboxes after that. We may keep records we are required to keep, and evidence as described in the Terms of Service (Sections 7 and 8).
Deleting a mailbox deletes its mail and can't be undone.

11. Ownership

We own the Business Service, our software, our scam-protection engine and the Xatheryn names and logos. You get a limited right to use the service for your business while you are subscribed. You may not copy, resell, sublicense or reverse engineer it. If you give us feedback we may use it freely.

12. Confidentiality

Each side will keep the other's non-public business information private and use it only for this agreement, except where the law requires disclosure or for the reports described in Section 8 of the Terms of Service. Your mail is covered by Section 8 above.

13. Disclaimer of warranties

The Business Service is provided "as is" and "as available," without warranties of any kind, whether express, implied or statutory, including merchantability, fitness for a particular purpose, title and non-infringement. We do not warrant that the service will be uninterrupted, secure or error-free, that any message will be delivered, received or kept, or that our scam and spam protection will catch every scam or never hold back a real message. Some jurisdictions do not allow these exclusions, so some may not apply to you.

14. Limitation of liability

To the fullest extent permitted by law, none of the Xatheryn Parties will be liable for any indirect, incidental, special, consequential, exemplary or punitive damages, or any loss of profits, revenue, business, data or goodwill, arising from or related to the Business Service, any message sent, received, lost, delayed, held back or removed, or the conduct of any User or third party, even if advised of the possibility. The total liability of the Xatheryn Parties for all claims will not exceed the fees you paid us in the twelve months before the claim arose. Nothing here limits liability that the law does not allow to be limited.

15. Indemnification

You agree to defend, indemnify and hold harmless the Xatheryn Parties from any claims, liabilities, damages, losses and expenses, including fines, penalties and reasonable attorneys' fees, arising from your and your Users' use of the Business Service, the mail you send, your domain, your violation of these terms or of any law, or your violation of anyone else's rights.

16. Disputes and governing law

We will first try to resolve any dispute informally: contact us, and give us 30 days. If it isn't resolved, it will be resolved by binding individual arbitration rather than in court, except that either side may bring an individual claim in small claims court if it qualifies, or ask a court to stop misuse of its intellectual property or confidential information. Each side waives any right to a jury trial and to take part in a class, collective or representative action. This agreement is governed by the Federal Arbitration Act and, otherwise, by the laws of the State of North Carolina, without regard to conflict-of-laws rules.

17. Changes to these terms

We may change these Business Terms as the Business Service changes. We will update the date at the top and tell administrators by email. If a change is material and you don't agree, you can cancel before it takes effect. Continuing to use the service afterwards means you accept the change.

18. General

If any part of these terms can't be enforced, the rest still applies. Not enforcing a right isn't a waiver of it. You may not transfer these terms without our written consent; we may transfer them with the business. Neither side is responsible for a delay or failure caused by something outside its reasonable control, except for paying money owed. These Business Terms, the Terms of Service and the Privacy Policy are the whole agreement between you and Xatheryn LLC about the Business Service.
