Terms of use
Last updated: November 5, 2026 · URL: https://www.mail-vex.com/en/terms · The Spanish version has the same content.
1. Who provides the service
MailVex is a product by AutomatLabs, a trading name of Víctor Gutiérrez Nogués (Spanish tax ID / NIF 09087078P), based at Vía Complutense 62, 28805 Alcalá de Henares, Madrid, Spain. AutomatLabs is the direct seller of the license — you pay through Stripe and the key is issued by AutomatLabs' own backend; there is no merchant of record in between. By installing the extension or buying a license, you accept these terms.
2. Not affiliated with Shopify
MailVex is an independent tool, not affiliated with Shopify, Inc. It is not "official", it is not "approved by Shopify", and it is not part of the Shopify App Store or the Shopify Partner Program. The name "MailVex" does not include the word "Shopify" and does not sound like it. MailVex does analyze and export data from the user's own Shopify Email campaigns, and says so plainly in its description — but that description of what the product does is separate from the brand name itself, which makes no use of Shopify's trademark.
No text in this tool, its Chrome Web Store listing or its sales page states or implies that Shopify, Inc. approves, sponsors or is associated with this product.
3. How it actually works (read before buying)
The extension does not use any official Shopify API or application credentials. It works by reusing, inside your own browser, the session you already have as an authenticated user in Shopify Email, to read the list of your campaigns and their metrics through internal Shopify endpoints that are not publicly documented.
This explicitly means:
- Shopify can change or block these endpoints at any time, without notice. If that happens, the extension may stop working, fully or partially, until it is adapted (if adaptation is possible) to the new shape of those endpoints.
- There is no guarantee of availability or service continuity. This is not a product defect: it is a real limitation of relying on an unofficial path to access the full HTML of your emails (today there is no official Shopify API that exposes it).
- Using the extension is a decision and a risk that you, as a merchant, take on. AutomatLabs takes reasonable care to minimize impact (see point 4), but cannot control or guarantee the future behavior of Shopify's systems.
- This is independent of whether you use the free or the paid version: both depend on the same endpoints.
4. What the extension does if something fails (graceful degradation, never fake data)
If an endpoint changes shape, stops responding or blocks the request, the extension shows a clear, specific error message (expired session, rate limit reached, unexpected response shape, offline, etc.) — it never invents or fills in with fabricated figures the data it could not read. An email that could not be read in full is marked as incomplete and retried on the next export; it is never shown as if it had data it doesn't.
The extension also respects the rate limits ("throttle") that Shopify itself indicates in its responses, to minimize the risk that the usage pattern looks anomalous.
5. Sales figures are Shopify's attribution, not an independent audit
Sales, orders and average order value shown in the dashboard are the attribution Shopify itself calculates (last non-direct-click model, LAST_NON_DIRECT_CLICK_ATTRIBUTION). They are not independently verified by AutomatLabs, nor a guarantee that those sales are solely due to that particular email. Use them as Shopify's attribution signal, not as a definitive accounting figure.
6. Plans, license and what each includes
| Free mode | Paid mode | |
|---|---|---|
| Demo mode | Yes | Yes |
| Export | Last 20 emails | All, with incremental export |
| HTML per email | No | Yes |
| Dashboard (KPIs, table, rankings, charts) | Over exported data (up to 20) | Over everything exported |
| Download | CSV | CSV + full JSON |
| Honest-calculation improvements (Wilson intervals, excluding "maturing" emails, etc.) | Yes, for everything exported | Yes, for everything exported |
The number of emails in free mode (20) may change in future versions; this will be announced in the extension and on this page if it changes.
License and seats: a license key activates paid mode on up to 2 seats. If you lose connection, activation stays valid for a 14-day grace period before reverting to free mode; once connection is restored, it revalidates automatically. An expired, revoked or refunded key reverts to free mode without deleting any data already exported — you can still view and download what you already had.
7. The Pro plan (MailVex Pro)
This point only applies if you subscribe to the Pro plan and use the web platform (app.mail-vex.com). If you only use the extension (free or paid) without the Pro plan, this point does not apply to you.
7.1. What it includes. You import your email history (by uploading the file the extension exports) to see more analytics than fit in the extension's dashboard, and generate email drafts with AI assistance based on your own store's "voice".
7.2. AI credits and their cap. Generating a draft uses more credits than regenerating a single piece of an already-generated draft — each action has its own credit cost, which may change between product versions. The Pro plan has a monthly quota with a hard cap (no extra usage beyond it); it renews on the 1st of each calendar month, regardless of which day of the month your subscription started. Unused credits do not roll over to the next month. If you run out, you can keep using the rest of the platform normally: only generating or regenerating is blocked until your quota renews on the 1st of the following month.
7.3. AI generation and human review — nothing is ever sent without your decision. Every draft the platform generates is visibly labeled "Generated with AI. Review it before using it." MailVex never sends anything to your subscribers on your behalf: you review, edit if you want, and decide whether to use it, when and how to send it, always from your own sending tools.
7.4. Non-payment cycle. If your Pro subscription falls behind on payment, you keep full access for a 14-day grace period and, after that, read-only and download access until 30 days from the non-payment have passed. If you catch up within that period, you recover full access without losing anything.
7.5. Cancellation and deletion. You can cancel your Pro subscription at any time from Stripe's billing portal or from your account settings. If you cancel directly (with no prior non-payment), read-only and download access lasts the 30 days following the cancellation. In both cases, on day 30 all your Pro content is automatically deleted: emails, HTML, metrics, drafts and files — your extension account, if you have one, is not affected. You can request immediate deletion of your account and all your data, without waiting for those periods, from your account settings.
7.6. Relationship with the DPA. While you use the Pro plan, AutomatLabs processes the content you import as a data processor on your behalf, under the data processing agreement (DPA), which forms part of these terms by reference. If you have a Pro account, you also accept the DPA.
7.7. Service limits. The Pro plan depends on you having already imported enough history (via the extension) to build a usable voice profile: without that, the platform tells you so and generates nothing, instead of failing silently. The platform also depends on the extension being able to keep exporting your campaigns (see points 3 and 4): if Shopify changes its internal endpoints, this can affect what you can import until the extension adapts.
8. Price and billing
The extension's billing model is an annual subscription, with a monthly option, charged directly by AutomatLabs through Stripe (no intermediate merchant of record). The Pro plan is also billed as a subscription through Stripe, with its own price. The exact price of each plan is set by AutomatLabs based on real costs and is published only on the sales page (never inside the extension, so a new version doesn't have to be published every time it changes) — it is not repeated here to avoid going stale. AutomatLabs is responsible for declaring and paying VAT on each sale, through the one-stop-shop (OSS) scheme for sales to EU consumers, and under the applicable regime for other sales.
9. Refunds and right of withdrawal
9.1. If you are an individual consumer within the European Union, you have the right to withdraw from your purchase (extension or Pro plan) within 14 calendar days of contracting it, with no reason required, with a full refund. To exercise it, write to info@mail-vex.com stating your decision to withdraw; we confirm it and process the refund without undue delay. This right is not waived simply by starting to use the service: when the payment flow asks you to expressly accept these terms (an acceptance checkbox at checkout — today, when buying the extension's license), that acceptance never waives your withdrawal right.
9.2. If you are a business (B2B), the commercial terms set here apply, not the consumer regime.
9.3. Regardless of the above, if you have a problem with the service (the extension doesn't work, it broke due to a Shopify change, a platform issue, etc.) you can also write to info@mail-vex.com: each case is reviewed reasonably, and a refund is offered where appropriate.
10. Prohibited use
You may not: resell, redistribute or share your license key with third parties outside your own organization (within the seat limit of point 6); attempt to bypass or tamper with license validation; use the extension or the Pro platform for purposes other than analyzing and creating emails for Shopify Email campaigns of stores you have legitimate access to; or use it in a way intended to pass itself off as Shopify or an official Shopify product.
11. Warranties and liability
The extension and the platform are provided "as is". Given what's described in points 3 and 4, AutomatLabs does not guarantee continuous availability, nor that Shopify will not change or block the endpoints it depends on. To the extent permitted by law, AutomatLabs' liability to you is limited to the amount you have paid in the last 12 months (license, Pro subscription, or both if you have both). Nothing in this point limits any rights that consumer protection law grants you on a mandatory basis if you are an individual consumer.
12. Updates to the extension, the platform and these terms
The extension and the platform are updated whenever they need to adapt to Shopify changes or product improvements. If these terms change in a material way, this is announced visibly in the extension, on the platform and on this page before the change takes effect.
13. Governing law and jurisdiction
Unless mandatory consumer protection law says otherwise, these terms are governed by Spanish law, with submission to the courts of AutomatLabs' domicile (Alcalá de Henares, Madrid) or, if you are a consumer, to the courts that correspond to your own domicile under that same law.
