Terms of service

The rules for using Messg while it is in early access: what it does, what you are responsible for, and what a generated draft can and cannot be trusted for.

Last updated 9 September 2026.

The agreement

These terms are the agreement between you and Messg for the use of www.messg.app and the product behind it. Using the service means you accept them. If you are accepting on behalf of a business, you confirm you may bind that business, and “you” means both.

Our privacy policy and cookies page are part of this agreement.

What the service is

Messg connects to a mailbox you own, reads the mail that arrives after you connect, decides which messages look like business enquiries, and writes a draft reply in your own words. It learns how you write from replies you have already sent.

A draft is a proposal, not an action. The service places drafts in your own drafts folder. Nothing is sent until you read it and press send. We do not request the Google permission that would let software send mail on its own.

Early access

The service is in early access. It is under active development, features change and are sometimes removed, and there is no uptime commitment. We may change, suspend or withdraw any part of it, and we will give notice where we reasonably can.

Treat it as an assistant you supervise, not as infrastructure you depend on unattended. Keep your mail in your own mailbox, which is where it already is: we add to it, we do not replace it.

Your account and eligibility

  • You must be at least 16 and able to enter a contract where you live.
  • Connect only a mailbox you own or are authorised by its owner to connect. Connecting someone else's mailbox without their authority is a breach of these terms.
  • Keep your sign-in address secure. Anyone with access to it can reach your account.
  • You are responsible for the people you invite to your account and for what they do in it.
  • Give us accurate information, and keep it current.

Acceptable use

Do not use the service to:

  • send bulk, unsolicited or deceptive mail, or anything that breaches anti-spam law (including CAN-SPAM, CASL and the UK PECR);
  • impersonate another person or business, or misrepresent who is answering;
  • break the law, infringe anyone's rights, or handle data you have no right to handle;
  • probe, overload or interfere with the service, or work around its limits, security or metering;
  • resell the service, or use it to build a competing product from its outputs;
  • breach Google's or Anthropic's terms through your use of Messg.

You are responsible for what you send

Every message that leaves your mailbox is yours. You read the draft, you decide whether it is right, and you press send. That is the only path out of this product, and it means the responsibility for the content, the promises, the prices and the commitments in a sent reply sits with you, not with us.

If a draft is wrong, edit it or discard it. If you are unsure of a price or a date, check it before you send. The product shows you where each fact in a draft came from precisely so you can.

AI output: what it can and cannot be trusted for

Drafts can be wrong. They are produced by a language model. A model can misread a question, miss a detail on a thread, or phrase something in a way you would not. Read every draft before sending it.

We make no warranty that a draft is accurate, complete or suitable for the enquiry it answers. In particular, we do not warrant any price, date, availability or other commitment that appears in generated text, including where the draft cites one of your own rate cards: the citation shows you the source so you can confirm it, and confirming it is your job.

Drafts are not legal, financial, tax, medical or professional advice, and must not be used as such.

Classification is not perfect either. The service may classify a genuine enquiry as something else and leave it alone, or draft to a message you would rather it had ignored. It stays a queue you supervise.

Intellectual property

Yours stays yours. Your mail, your drafts, your rate cards, your business facts and the voice profile learned from your replies belong to you. We claim no ownership of them, and we take the licence to use them only for what this agreement and the privacy policy describe: running the service for you.

As between you and us, the text of a draft the service produces for you is yours to use, edit and send as your own.

Ours stays ours. The software, the interface, the name Messg and its logo are ours. These terms grant you a limited, revocable, non-exclusive, non-transferable right to use the service, and nothing more.

If you send us feedback, we may use it to improve the product without owing you anything for it.

Fees

There are no fees today. Early access is free, we take no payment details, and there is no billing in the product. The Usage screen shows what your account costs us to run so the number is never a surprise later.

If we introduce charges we will tell you before they apply and you will be able to decline and stop using the service. We will not begin charging for use you have already had.

Third-party services

The service depends on Google (Gmail) and Anthropic (Claude), and your use of it is also subject to their terms. We do not control them. If one of them changes, limits or withdraws access, parts of the service may stop working, and that is outside our control. The privacy policy names every sub-processor and what each one does.

Suspension and termination

You can stop at any time: disconnect your mailbox, revoke access at Google, and ask us to delete your account. The privacy policy sets out how.

We may suspend or close an account that breaches these terms, that puts the service or another user at risk, or where the law requires it. Where the circumstances allow, we will warn you first and give you a chance to put it right. On termination your right to use the service ends; sections that by their nature survive (intellectual property, disclaimers, liability, governing law) continue to apply.

Disclaimer

The service is provided “as is” and “as available”. To the fullest extent the law allows, we exclude all implied warranties, including merchantability, fitness for a particular purpose, non-infringement, and any warranty that the service will be uninterrupted, timely, secure or error-free, or that any output will be accurate. Nothing in these terms excludes liability that cannot lawfully be excluded, and if you deal with us as a consumer, your statutory rights are unaffected.

Limitation of liability

To the fullest extent the law allows, we are not liable for indirect, incidental, special, consequential or punitive loss, or for lost profits, lost revenue, lost business, lost goodwill, or lost or corrupted data, however caused.

Our total liability arising out of or relating to the service, in aggregate, is limited to the greater of the amount you paid us in the 12 months before the claim (which, while the service is free, is nothing) and one hundred Canadian dollars (CAD 100).

This limit does not apply to liability for death or personal injury caused by negligence, for fraud or fraudulent misrepresentation, or to any other liability that cannot lawfully be limited.

Indemnity

You will indemnify us against claims, losses and reasonable costs arising from your use of the service in breach of these terms, from mail you send, or from your connecting a mailbox you were not authorised to connect.

Changes to these terms

We may update these terms as the product changes. The date at the top moves when we do. For a material change we will give notice by email or in the product before it takes effect; continuing to use the service after that means you accept the new terms. If you do not, stop using the service and ask us to delete your account.

Governing law

These terms are governed by the laws of the Province of British Columbia and the federal laws of Canada that apply there, without regard to conflict of laws rules. The courts of British Columbia have exclusive jurisdiction, except that if you are a consumer resident elsewhere, you keep the benefit of any mandatory protections and the right to bring proceedings in the courts of your own country.
