Postmetry

Terms of Service

What you can expect from Postmetry, what we expect from you, and what happens when either side falls short. They cover the site, the free tools and the customer area.

Updated on

1. Subject

1.1 What these terms cover

These terms govern access to and use of the Postmetry site, the free tools it offers, the public brand reports, and the customer area, published by fstck (“we”). They form a whole together with the privacy policy and the cookie policy.

By using the service, you accept them. If you act on behalf of an organization, you represent that you have the authority to bind it, and “you” refers to it.

1.2 A service for professionals

Postmetry is for people who send emails on behalf of an organization or who measure their quality: marketing, CRM, compliance and technical teams, agencies and vendors. It is not designed for consumer use, and you confirm you are using it as part of your professional activity.

1.3 Definitions

In this document:

  • “Service” means the site, the free tools, the public reports and the customer area, taken together;
  • “Free tools” means the email audit, the suspicious email check and the tracking pixel diagnostic, all accessible without an account;
  • “Public report” means a brand's page, built from the messages it has sent to addresses we control;
  • “Customer area” means the part of the service accessible with an account, which carries monitoring over time;
  • “Deposited content” means any message you send us — an .eml file, a forwarded email, an imported mailbox — and the data it contains;
  • “Finding” means an observable fact extracted from a message by an analyzer, with its evidence;
  • “Claimed brand” means a brand for which you have proven an address on its domain.

2. The service

2.1 What we measure

We subscribe to brands' communications from addresses we control, we archive every message received as is, and deterministic analyzers extract findings from it: open trackers, click tracking, unsubscribing, authentication, technical reading. Every finding carries its evidence — an excerpt or a position within the message — and replays identically on the same piece.

The free tools apply the same analyzers to a message you deposit with us.

2.2 What a finding is, and is not

A finding describes what a subscriber received. It does not legally qualify a practice, does not constitute legal advice, and does not replace the opinion of a legal professional. A score is a measurement according to a published method; it does not attest to an email's compliance, nor does it establish the opposite.

The decisions you make based on a report are yours.

2.3 What we don't access

The service needs no access to your systems: no sending platform, no CRM, no API, no account. We will never ask you for a login, and we never load any remote resource contained in a message — doing so would trigger the trackers we measure.

2.4 Free tools

They are open to everyone, without an account, and the report is given in full. In return:

  • each request covers one email;
  • the report's link is private, and you're responsible for keeping it;
  • technical caps limit the number of requests, to protect the service;
  • we may change or withdraw a free tool at any time.

2.5 Public brand reports

A public report describes the messages a brand has sent to our addresses, as it would to any subscriber. It is public, free, and given in full, including to the brand concerned. We only publish measurements and thumbnails there, never the full reproduction of a message, and we mask the addresses.

A brand that disputes a finding writes to us; we republish the calculation and its evidence, and correct any error on our side. An accurate report is not withdrawn at a brand's request.

Featuring a brand on the homepage is an editorial decision, made brand by brand, never derived from a score or tied to a subscription.

2.6 The customer area

The customer area carries monitoring over time: the brands you follow, the history of findings, alerts on status changes, exports. It is offered in beta: its features may change, and we attach no availability commitment to it as long as this notice appears on the site.

3. Account and access

3.1 Opening an account

The account opens via a link sent to a professional address; there is no password. You are responsible for the inbox that receives this link, and for what is done from the account until you report to us any access you did not authorize.

The information you give us must be accurate and kept up to date. Access is personal: it isn't shared, it's invited.

3.2 Members

An account holder may invite members to it and revoke their access. They are responsible for how those members use it.

3.3 Claiming a brand

Claiming a brand requires proving an address on its domain. You represent that you are authorized to act on its behalf. The monitoring addresses we give you to add to your sending platform are meant for that brand alone: adding them to a third party's lists is prohibited.

These addresses also serve as sentinels. A claimed address is never given to anyone else: if it receives a message from another sender, we tell you, with the fact and its date, without qualifying the cause.

3.4 Access security

Report to us without delay any use of your account you did not authorize. We may suspend access while we work out what is happening.

4. The content you deposit

4.1 It stays yours

You retain all your rights over the deposited content. You grant us only what the service needs: to archive it, analyze it, produce its report and its preview, and make them accessible to you.

4.2 It stays private

Deposited content is attached to your account, whether it was created for a free tool or for the customer area. It never enters any public aggregate, any sector comparison, or a brand's public report. This separation is a constraint of our database, not an internal rule.

The public corpus, meanwhile, is built solely from messages received on our own subscriptions: deposited content never feeds it.

4.3 What you warrant

You warrant that you have the right to send us this content, including any personal data it may contain — yours, a recipient's, a sender's — and that depositing it violates no third party's rights and no confidentiality obligation. You do not deposit a message you did not receive or are not authorized to hold.

4.4 What we do with it

The message is archived as is, once, and never modified: that's what lets us replay a measurement months later. Its preview blocks every remote resource and makes no link clickable. It is deleted along with your account, and on request.

5. Prohibited uses

The service is open, and that openness rests on a few rules. It is prohibited to:

  • bypass technical caps or form protections, or automate requests in volume;
  • try to identify or collect the addresses through which we receive the public corpus's messages;
  • access, or attempt to access, another account's data or a report whose link you have not received;
  • reproduce the site or systematically extract its data, by script or otherwise;
  • present a report or a finding separated from its date, its basis or its source, or alter its content;
  • use the service to send unsolicited messages, or to harm a person or an organization;
  • deposit unlawful content, or content you have no right to hold.

A breach may result in the suspension or closure of access, without prejudice to our other rights.

6. Intellectual property

6.1 The service

The site, its code, its texts, its analyzers, its marks and the name Postmetry belong to fstck. These terms transfer no rights to you over them, other than the right to use the service as offered. The “Brand” page explains how to credit the name and use the marks.

6.2 Reports

Reports and findings are produced by us. You may share them, quote them and pass them on to your team or your vendors, with their date and source. A brand report published on the site may be cited under the same conditions.

6.3 Your name

We do not name our customers or use their logo without their written consent. Featuring a brand on the site is never tied to a subscription.

6.4 Your feedback

If you suggest an improvement to us, we may implement it without obligation or compensation.

8. Termination and deletion

8.1 By you

You may stop using the free tools at any time. You may request the deletion of your account from your settings: the request stays open for seven days, during which it can be cancelled with one click, after which erasure is carried out and cannot be reversed. It covers your account data and your deposited content, never the public corpus.

8.2 By us

We may suspend or close access in the event of a breach of these terms, after notifying you, unless the breach requires immediate action. We may also end the service or part of the service: account holders are notified by email beforehand, with time to export their analyses.

8.3 What survives

Clauses that by nature must survive — intellectual property, liability, confidentiality, governing law — remain in force after the relationship ends.

9. Liability

9.1 Availability

The service is provided as is. We do what's needed to keep it running, but we do not guarantee uninterrupted access or that it will be error-free. Maintenance may make it unavailable; we schedule it at the times that cause the least disruption.

9.2 Collection doesn't depend on us alone

The public corpus is built from what brands send. A brand may stop sending, remove our addresses from its lists, or block a sign-up. We therefore guarantee neither a brand's coverage, nor the continuity of its history, nor any volume of messages.

No date is ever promised for a brand's entry into the corpus: we show what is available now.

9.3 What a report does not guarantee

A report describes a message as it arrived on one address. Another recipient may have received a different version. An absent finding is not proof that a practice is absent. We do not guarantee that a report is complete, nor that it is enough to establish a brand's situation with regard to a rule.

9.4 Limitation

Our liability is limited to direct, proven damages we have caused. It cannot exceed the amounts you have paid us, if any, over the twelve months preceding the event giving rise to it, and remains limited, for free use, to the extent permitted by law. We are not liable for indirect losses — loss of profit, loss of data you did not back up, damage to reputation, decisions made on the basis of a report.

This limitation does not apply in the event of gross negligence or willful misconduct, nor where the law prohibits it.

9.5 Your liability

You are responsible for the content you deposit, for how you use reports, for the members you invite, and for the brands you claim. You indemnify us against any resulting third-party claim.

10. Personal data and confidentiality

10.1 Personal data

What we do with personal data — yours, and any contained in deposited content — is described in the privacy policy, which forms part of these terms.

For content you deposit that contains third parties' personal data, we act on your instructions and solely for the service's purpose. A data processing agreement compliant with Article 28 of the GDPR can be entered into on request.

10.2 Privacy

What we learn from your account — your brands, your deposited content, your exchanges with us — remains confidential. We disclose it only to vendors necessary to the service, bound by the same obligation, or when the law requires it. The public corpus and public reports are not confidential information.

10.3 Report a vulnerability

If you discover a security vulnerability, write to us with the steps to reproduce it. We respond to every good-faith disclosure, fix it, and credit those who want to be credited. Excluded are tests that degrade the service for others, social engineering, and access to data that isn't yours beyond what's needed to demonstrate the vulnerability.

11. General provisions

11.1 Changes

We may modify these terms. The date at the top of the page shows when. Account holders are notified by email of changes that matter; continuing to use the service after they take effect constitutes acceptance.

11.2 Entire agreement and severability

These terms and the policies they cite form the entire agreement between us. If a clause is found invalid, the others remain in force.

11.3 Assignment

You may not assign your rights without our written consent. We may assign ours to a company that takes over the business, notifying you of it.

11.4 Force majeure

Neither party is liable for a failure caused by an event beyond its reasonable control.

11.5 Governing law and jurisdiction

These terms are governed by French law. Any dispute not resolved amicably is brought before the competent courts of Paris. In the event of a discrepancy between a translation and the French version, the French version prevails.
