Terms of Service

Last updated: 5 September 2026

These Terms are an agreement between Amino Engine ("Amino Engine", "we", "us") and the business that opens an account ("you", "your brand"). By creating an account, clicking to accept, or using the service, you agree to them. If you are agreeing on behalf of a company, you confirm you are allowed to bind that company.

Amino Engine is operated by [LEGAL ENTITY NAME], a [ENTITY TYPE] with its principal place of business at [BUSINESS ADDRESS], United States.

1. What the service is

Amino Engine is an email marketing platform. You use it to store your contacts, build campaigns and automated flows, and send email to people who have agreed to hear from you. We host the app at app.aminoengine.com, run the mail servers that deliver your messages, and record what happened to each one.

We are the sending platform, not the sender. You choose who is on your list, you write what the email says, and you decide when it goes out. Your brand name is on the message. We provide the pipes, the tooling and the reporting.

We do not review your messages before they send. We may review them afterwards if something goes wrong — see section 8.

2. Your account

You need an account to use the service. You must give us accurate information, keep your password to yourself, and tell us promptly if you think somebody else has got into your account. Everything done under your account is your responsibility, including anything done by people you invite to it.

You must be at least 18 and using the service for a business. The service is not for personal use.

3. Acceptable use

Your use of Amino Engine is also governed by our Acceptable Use Policy and our Anti-Spam Policy, which form part of these Terms. Those documents are specific about what you may and may not send, because we serve peptide and research-compound brands and the rules there are unusually strict. Read them. Breaking them is a breach of this agreement.

4. Your contacts, your consent, your content

You own your contact list and your content. We do not sell it, rent it, mine it for our own marketing, or use it to build a list of our own.

In exchange, three things are entirely on you:

• Consent. Every person you email must have agreed to hear from you, in a way that is valid where they live. You must be able to show us where and when they agreed if we ask. Purchased, scraped, rented and "appended" lists are banned outright.
• Content. What your emails say — claims, offers, prices, product descriptions, images, links — is yours. You are responsible for it being legal, accurate and honest in every place you send it, including any rules that apply to the products you sell.
• Law. You must follow the law that applies to you: CAN-SPAM in the United States, CASL in Canada, the GDPR and PECR in the UK and EU, the TCPA if you ever send SMS, and whatever else applies in your own jurisdiction and your recipients'.

Where we process personal data about your subscribers, we do it on your instructions as your processor. Our Data Processing Addendum sets those terms out and is incorporated into these Terms.

You give us the permission we need to host, copy, transmit and display your content for the sole purpose of running the service for you. That permission ends when your content is deleted.

5. What we do to keep the mail flowing

We run shared and dedicated sending infrastructure. Deliverability depends on the behaviour of everyone using it, so we monitor complaint rates, bounce rates and engagement, and the platform will automatically slow or stop marketing sends for an account whose numbers get dangerously high. Transactional mail — receipts, password resets and the like — keeps flowing when marketing is stopped.

We will make reasonable efforts to keep the service available, but we do not promise uninterrupted service and there is no uptime SLA on the standard plans. [SLA COMMITMENT, IF ANY — leave out if none.]

6. Fees, trial, and cancellation

Free trial. New accounts get a 7-day free trial. You can build everything during the trial. Sending is capped during the trial. When the trial ends you pick a plan; nothing you built is deleted if you do not.

Plans. The monthly plan is priced by how many emails you send per month, in tiers. Current prices are shown in the app before you buy and on our pricing page. Prices are in US dollars and exclude any tax we are required to collect.

Add-ons. We also sell one-time "done for you" work (we build your flows) and a monthly managed-campaigns add-on (we write and send your campaigns for you). These are bought separately and priced per item at the price shown at checkout.

Payment. Payments are processed by Stripe. We do not see or store your full card number. Subscriptions renew automatically each month until you cancel.

Cancelling. You can cancel any time from Settings → Billing. Cancellation takes effect at the end of the period you have already paid for; you keep access until then. We do not give refunds for partial months, except where the law requires one. [CONFIRM REFUND POSITION — e.g. any goodwill window.]

Failed payments. If a payment fails, your account is marked past due and you keep sending for a 7-day grace period while we retry and tell you. After that, sending stops until the payment goes through. Your data is not deleted at that point — see section 10.

Price changes. We may change prices. We will give you at least [NOTICE PERIOD — suggest 30 days] notice by email before a change affects your next renewal. If you do not want the new price, cancel before it takes effect.

One-time work. Done-for-you flows and other one-time purchases are non-refundable once we have started building. [CONFIRM: point at which work is "started" for refund purposes.]

7. Beta and changing features

Some features are labelled beta or early access. They may change or disappear. We may add, change or remove features generally; we will not remove something you are actively paying for without reasonable notice.

8. Suspension and termination

We may pause your sending, suspend your account, or close it if:

• you break the Acceptable Use or Anti-Spam policies;
• your complaint or bounce rates threaten the deliverability of other customers on our infrastructure;
• we receive credible reports of abuse, or a blocklist or mailbox provider acts against traffic from your account;
• your payment is more than the grace period past due;
• we are required to by law, or by a provider we depend on.

Where it is safe and practical we will contact you first and give you a chance to fix it. Where the risk to other customers is immediate — a spam run, a purchased list, a sudden spike in complaints — we will pause sending first and talk afterwards. Sending on shared infrastructure means one account's behaviour costs everyone, and we will act to protect the others.

You may close your account at any time from Settings → Billing.

9. Data export when you leave

Your data is yours and you can take it with you. The app exports your contacts, message history and analytics as CSV at any time while your account is open, and we would rather you exported before you close the account than after.

If you ask within [EXPORT WINDOW — suggest 30] days of closing, we will provide an export. After that, deletion has run and we may not be able to.

10. Deletion

When your account is closed, we delete or anonymise your customer data on the schedule described in our Privacy Policy and the DPA. Two things deliberately survive: records we are required to keep (billing and tax records), and suppression entries — the one-way hashed record that somebody unsubscribed or asked to be forgotten. We keep those forever, in a form that identifies nobody, because deleting them is how a person who opted out gets emailed again.

11. Confidentiality

Each of us may learn things about the other that are not public. Neither of us will share them outside our own staff and contractors who need them, except where the law requires it.

12. Warranties and disclaimer

You promise that you have the right to send everything you send, that you have consent for every recipient, and that your use of the service will not break the law.

We provide the service "as is". To the fullest extent the law allows, we disclaim all implied warranties, including merchantability, fitness for a particular purpose and non-infringement. We do not warrant that every message will be delivered, that it will land in the inbox rather than the spam folder, or that the service will be error-free. Deliverability depends on mailbox providers we do not control and who have no contract with us.

13. Limitation of liability

To the fullest extent permitted by law:

• Neither of us is liable to the other for indirect, incidental, special, consequential or punitive damages, or for lost profits, lost revenue, lost data or lost goodwill, even if we were told they were possible.
• Our total liability for all claims arising out of or relating to these Terms is limited to the amount you actually paid us in the [LIABILITY CAP PERIOD — suggest 12] months before the event giving rise to the claim.

Nothing here limits liability that cannot be limited by law — including fraud, wilful misconduct, or death or personal injury caused by negligence.

These limits do not apply to your obligation to pay us, or to your indemnity below.

14. Indemnity

You will defend and indemnify us against claims, losses and costs (including reasonable legal fees) arising from your content, your contact list, your lack of consent for a recipient, your products, or your breach of these Terms or the Acceptable Use Policy.

15. Governing law and disputes

These Terms are governed by the laws of the State of [STATE], United States, without regard to its conflict-of-laws rules. Any dispute will be brought exclusively in the state or federal courts located in [COUNTY/CITY, STATE], and both of us consent to those courts' jurisdiction.

[ARBITRATION AND CLASS-ACTION WAIVER — decide whether to include, and in what form.]

If you are in the EU, the UK or Canada, nothing here removes rights you have under your local consumer or data-protection law that cannot be waived by contract.

16. Changes to these Terms

We may update these Terms. When we make a material change, we will update the "Last updated" date and tell you by email or in the app at least [NOTICE PERIOD — suggest 30] days before it takes effect. Continuing to use the service after that means you accept the new version. If you do not accept it, cancel before it takes effect.

17. General

These Terms, together with the Acceptable Use Policy, Anti-Spam Policy, Privacy Policy and DPA, are the entire agreement between us on this subject. If any part is found unenforceable, the rest stays in force. Neither of us is in breach for delays caused by events outside our reasonable control. You may not assign this agreement without our consent; we may assign it to a successor of our business. Nothing here creates a partnership, agency or employment relationship.
