The Terms Behind This Site

Using supersonicmails.com, submitting a form, booking a call or applying for an audit means you accept these terms. If any part of them is unacceptable to you, the answer is to stop using the site — there is no version of this where you use it and the terms do not apply.

If you are agreeing on behalf of a company, you are confirming you are allowed to bind that company.

Supersonic Mails is a retention marketing agency working with ecommerce brands on email, SMS and lifecycle revenue. Our contact and registered details are at the bottom of this page.

This page governs the website and any general dealings before you become a client. It is not your service contract.

If you engage us, the scope, fees, timelines, deliverables, ownership and termination terms live in a separate signed agreement, proposal or statement of work. Where that document and this page disagree, that document wins. Nothing here quietly overrides something you negotiated.

Ordinary rules, briefly. Do not:

• Use the site for anything unlawful, or in any way that interferes with it working for other people.
• Attempt to access parts of it you were not given access to.
• Scrape, crawl or bulk-copy the content, designs or case studies without written permission.
• Submit information you know to be false, or someone else's details as your own.
• Republish our material as your own work.

We can restrict or block access if we reasonably believe any of the above is happening.

The audit is free and it is genuinely an audit — we look at your account and tell you what we find. That said, be clear about what an application is:

• It does not create a client relationship, and it is not an offer we are bound to accept.
• We may decline. We turn down brands that are not a fit more often than we take them.
• Anything we tell you in an audit is our opinion based on limited access and limited time. Acting on it is your decision.
• You confirm the information you give us is accurate, and that you are entitled to grant any account access you grant us.

By applying you agree we may contact you about that application using the details you provided.

This section is deliberately blunt, because every figure we publish is a real client's and we would rather be trusted than impressive.

The revenue figures, open rates, returning-customer rates and screenshots in our case studies are real, taken from the client's own platform reporting for the period stated, and published with that client's permission.

They are also historic, specific to that brand, and no indication of what your brand will do. What a retention system produces depends on things we do not control and cannot fix from the outside: your product and pricing, margin, traffic quality and source, list size and how it was built, sender history, offer, creative, seasonality and the state of your store.

So: we make no guarantee of any revenue figure, growth rate, open rate, retention rate or return on spend. Anyone in this industry who does is selling you something. Where a specific, measurable commitment is made to you, it will appear in your signed agreement — never in a marketing claim on a web page.

Some of our work is getting brands out of the spam folder and back into the inbox. It is worth being precise about who decides that.

Mailbox providers — Gmail, Yahoo, Outlook, Apple and the rest — decide where your mail lands, using signals and thresholds they do not publish and change without notice. We influence those signals: authentication, list hygiene, sending patterns, segmentation, content and engagement. We do not control the outcome, and nobody can.

Recovering a damaged sending reputation also takes time and usually requires sending less before you can send more. Where we recommend pausing sends, suppressing segments or reducing volume, following that advice is your choice — and declining it materially changes what is achievable.

• Fees, billing dates, currency and scope are set out in your agreement or invoice.
• Retainers are billed in advance unless we have agreed otherwise in writing.
• If an invoice goes unpaid past its due date, we may pause work until it is settled. We will tell you before we do.
• Work outside the agreed scope is quoted and approved before it starts, not billed as a surprise afterwards.
• You are responsible for your own platform subscriptions and sending costs.

The site itself — its copy, design, structure, our frameworks and the way we present them — belongs to us. You may not copy or republish it without written permission.

Work we produce for a client is dealt with in that client's agreement. As a general position: once you have paid for it, the campaigns, flows, templates and copy we build for your brand are yours to keep and keep using. What stays ours is the underlying method — the frameworks, checklists and internal tooling we bring to every engagement and would still own if we had never met.

Anything you give us — brand assets, product imagery, copy, data — remains yours. You confirm you have the right to hand it over, and you allow us to use it for the purpose of doing your work.

We ask before we publish. Every case study on this site went up with the client's agreement, and a client can ask us to anonymise or remove theirs at any point — some of the brands we work with prefer not to be named at all, which is why one of our studies is not.

Our work runs on other companies' software — Shopify, Klaviyo, Omnisend and similar. Your use of those tools is governed by their terms, not ours.

We are not responsible for their outages, pricing changes, feature removals, policy decisions, account suspensions or data loss. If one of them breaks or changes the rules mid-engagement, we will work around it — but we cannot be liable for it.

How we handle personal information is set out in our Privacy Policy, which forms part of these terms. Read the Privacy Policy.

We publish this site in good faith and keep it accurate, but we provide it “as is” and “as available”. We do not warrant that it will be uninterrupted, error-free, secure, or that the information on it is complete or current at the moment you read it.

Nothing on this site is legal, tax, accounting or financial advice.

To the fullest extent the law allows, we are not liable for indirect or consequential loss, lost profits, lost revenue, lost data, or loss of anticipated savings arising from your use of this site or reliance on anything published on it.

Where liability cannot be excluded, it is limited to the amount you have actually paid us in the three months before the claim arose — or, if you are not a client, to a nominal sum.

None of this attempts to exclude liability for fraud, or for anything that cannot lawfully be excluded.

We may suspend or withdraw access to the site where these terms are being breached, where the site is being misused, or where continuing to provide it creates a legal or security risk. The sections that ought to survive that — ownership, liability, governing law — do.

These terms are governed by the laws of Nepal, and the courts of Nepal have jurisdiction over any dispute arising from them. Where you deal with us as a consumer in your own country, this does not remove protections you have under your local law that cannot be contracted out of.

We may update these terms. The revised version is posted here with a new date at the top, and continuing to use the site after that means you accept it. Terms already agreed inside a signed client contract do not change because this page did.
