EMAIL SECURITY QUESTIONS, ANSWEREDQuestions should have clear answers.

What Jatzo can help with, what the results mean and how your information is handled.

Three everyday messages worth a second look: an unexpected invoice, a login request and a shared document.

THE PRODUCT

How Jatzo checks an email.

How the analysis works

What does Jatzo check?

Identity, authentication, intent, social-engineering behaviour, links, supported attachments, routing evidence and campaign context are combined into one explainable assessment.

See the investigation guide

How does Jatzo decide whether an email is risky?

Jatzo combines more than one hundred explainable checks across sender identity, From/Reply-To/Return-Path relationships, SPF/DKIM/DMARC evidence, source routing, message intent, social-engineering behaviour, impersonation, link structure, attachments and campaign context. Signals are grouped and deduplicated so repeated evidence does not simply inflate the score. A pass written in an uploaded email header is not independently verified by Jatzo. It is not proof of who sent the message and does not cancel independent warning signs.

One result, as the analyser shows it: real Jatzo output for a fictional message, not a live check of your mail.

Email risk score
91/100 Risk gradeVery high risk

Multiple strong indicators suggest this email may be phishing or malicious. Do not click links, open unexpected attachments, or provide sensitive information until independently verified.

What it wantsGet you to sign in or reveal account access

Top reasons for this score

  • +22Possible brand impersonation

    A known brand's name from a domain it does not use, with signs of disguise, is impersonation.

  • +18An impersonated brand warns about your account

    A fake warning about your account from a brand that did not send it is how account takeover starts.

  • +10Account security alert lure

    Alarm about your account is used to rush you into signing in on a copied page.

Recommended action

Do not use the supplied sign-in path. Open the real service independently and check your account there.

How does Jatzo detect impersonation and deceptive infrastructure?

Verified brand-domain families, a broad identity watchlist and generic organisation checks are combined with lookalike domains, Unicode/confusable characters, suspicious subdomains, machine-like sender infrastructure and identity-coherence checks. The engine asks whether the displayed identity, sender address, Reply-To, Return-Path, sending domain and destinations make sense together. A watchlist match or unusual domain alone is supporting context, not automatic proof of phishing.

Does Jatzo learn from reports?

Yes, but cautiously. Threat Memory can use explicitly confirmed malicious reports as supporting evidence in later checks. Campaign Intelligence on the paid plans connects related reports using keyed fingerprints within the personal account or business workspace. Jatzo never compares one customer's mail with another's. Jatzo does not expose another user's raw email or automatically treat its own previous High risk verdicts as ground truth.

Is Jatzo only an email-security product?

Email investigation is the first live tool, not the intended limit of Jatzo. The broader direction is an approachable online-security toolbox, with planned capabilities such as isolated visual investigation of suspicious destinations.

Can I learn before buying?

Yes. The first lesson of Phishing fundamentals is free. Every module is included with Business Pro; buying the catalogue on its own is not enabled yet. A completion record is not an accredited qualification.

WHAT THE SCORE MEANS

Every check ends in a number from 0 to 100.

The number is not the answer on its own. The band it falls in is what tells you what to do next, and every point traces back to a named finding.

  1. Low risk 0 to 29

    Few warning signs. Still check anything unexpected about money, passwords or access through a route you already trust.

  2. Suspicious 30 to 49

    Pause. Something about this message does not add up, so confirm it through a contact you already have rather than one the message gives you.

  3. High risk 50 to 74

    Do not do what the message asks. Verify independently, and tell whoever looks after IT if you are at work.

  4. Very high risk 75 to 100

    Treat this as an attack. Do not reply, click, pay or sign in, and report it.

A low score is not a promise that a message is safe, and a high one is not proof of a crime. Verify anything unexpected about money, passwords or access through a route you already trust.

OUTLOOK

Jatzo in your inbox.

Jatzo for Outlook

Can I check an email directly from Outlook or Gmail?

In both, yes, on Personal and above. Jatzo adds a Check this email button and the message is checked by the same engine as the website. In Outlook you add the add-in file from your account page. In Gmail you install Jatzo from the Google Workspace Marketplace, then paste a connection code from your account page once. On Free, upload the .eml file or paste the original email source on the website.

Which Outlook versions are supported?

Outlook for Windows, including the new Outlook, Outlook for Mac, Outlook on the web, and Outlook on iPhone and Android. On a phone, Outlook does not give add-ins the delivery details the sender checks need, so the result says what it could not check. Where Jatzo works

Why can the same email score differently on a phone?

Outlook on a phone does not give add-ins the delivery details, so the sender checks cannot run there. The pane says what it could not check, and the same message checked on a computer can score differently for that reason.

The Gmail install did not work. What now?

This is a limitation of Google’s add-on platform rather than anything in Jatzo, and it affects every add-on built the way Google asks for. With more than one Google account signed in, Google chooses one of them itself when you install, whichever you were looking at, and the install fails. The page it shows says only that it cannot open the file, whatever the real cause was. We cannot change any of that from our side.

For a business, the simplest route avoids it completely. Ask whoever administers your Google Workspace to install Jatzo for the whole domain from the same listing. Nobody then installs anything themselves and the problem never arises. This is how most teams should do it.

Installing it for yourself. Open a private window, sign in to the one Google account you want Jatzo on, and install from there. Signing out of the others works too. Switching accounts first does not, for the reason above.

If your administrator restricts which add-ons may be installed, an install by one person is refused without saying so. A domain install by that administrator is the answer there as well.

If none of those is it, tell us and say which Google account you used and what the page said. Jatzo cannot see a failed install from its side, so we only know about it if you say.

PRIVACY

What happens to your information.

Security and privacy in full

What happens to my email?

Your privacy matters. Jatzo processes the raw email and its attachments for the analysis, then releases them from application processing; it does not save the raw message or attachment contents in case history. History does keep your email subject as the case title, the date, score and compact findings. Subjects can contain personal information. Temporary URL intelligence and keyed fingerprints are explained in our Privacy Notice.

Read Privacy

Are uploads isolated?

Supported file parsing runs in a restricted disposable worker. The website still handles uploads and results, and isolation cannot eliminate every security risk. It does not make an attachment safe to open on your own device.

Why is a detailed PDF unavailable later?

Detailed evidence is temporary for up to 30 minutes and can disappear sooner after a restart or memory limit. The saved case summary remains within your history limit. JPTI exports need their temporary provider evidence. Download important reports promptly; the Case ID links them to your history.

PLANS

What each plan includes.

Compare the plans

Which plan is right for me?

Free covers occasional checks on the website. Personal puts Jatzo inside Outlook and adds the full evidence: links, attachments, technical detail, source IP, live link reputation and PDF reports. Business covers a team, with a login for each person and one allowance shared by everyone. Business Pro adds the Training Centre for everyone you add and bulk checking on the website. Every plan runs the same detection engine.

Compare plans

How many emails can I check together?

Bulk checking is part of Business Pro and above, up to 50 per batch. Jatzo processes files in sequence and each successful check uses your allowance. Business Pro keeps up to 1000 cases, Business 500 and Personal 60.

Does my plan include QR checks?

Yes, on every plan, Free included. Jatzo reads QR codes out of attached and inline images, inside the same isolated container that handles every attachment, and checks where the code leads exactly as it would a link you could click. The same checking engine runs whichever plan you are on, so the score is the same: the result says the destination came from a code, so you know what you are looking at, and it says so plainly when a code is the only way to act on a message, which is how this kind of attack is usually built. Personal and above add the attachment evidence behind it: which file held the code, how many of its pages or pictures were read, and what could not be. Paid plans also check the destination against Google Web Risk when it is enabled. Codes on the first three pages of an attached PDF are read the same way: each page is drawn as a picture inside the container, and nothing in the PDF is run. So are codes in the pictures inside an attached Word, Excel or PowerPoint file. A few limits worth knowing: PDF pages after the third are not looked at, and a document with more pictures than Jatzo reads is marked as not fully checked. Older .doc, .xls and .ppt files are not read, and neither are the vector pictures, such as EMF and SVG, that Office uses for some logos and drawings, or images the message only links to rather than attaches. A code Jatzo could not read is not the same as a code that is safe.

Will I see ads?

Free accounts include clearly labelled ad space. This build uses a Jatzo training promotion without third-party advertising trackers. Personal and above are ad-free.

Can Jatzo email me the results?

Paid plans can request a PDF, or a JPTI report, to their registered account address when Jatzo has secure email delivery turned on. You cannot enter another recipient. In a business team, Report this to IT sends the report to the IT email address the workspace admin set instead, and that report names the original sender and the subject. A request accepted for delivery can still be delayed or filtered by your mail provider.

TEAMS

Jatzo across a business.

How Jatzo works for a business

Can my whole business share a login?

Business and Business Pro provide a workspace with separate logins and one allowance shared by the team. The admin and moderators invite colleagues and can see all retained business cases; members can open their own. An account in a team is a business account, so every check it makes goes to the team. Never share passwords.

Who in a team can see my checks?

Every check made by a business account goes to its workspace. Members can open their own cases, and the workspace admin and moderators can see all retained business cases. Who can see what

Business accounts and personal checks

An account in a business workspace saves every check to that workspace, and has no personal history or personal allowance while it is a member. For personal checks, use a separate account with a personal email address.

The full rules, including what joining a workspace does to checks already saved, are in the Terms of Service.
