Phixo
Pricing
- Free Tier
- 10 free scans a day
Summary
Your spam filter was trained on yesterday's attacks — the convincing lookalike domain that arrived this morning slipped right through. Phixo is a Chrome extension that sits inside Gmail and Outlook on the web and runs a four-layer threat scan on every email before you click anything.
The scan pulls from five intelligence sources — rules engine flags, Google Safe Browsing, AI reasoning, domain reputation, and link checking — and returns a risk score with a plain-English breakdown of exactly what looks wrong. That explanation layer is the differentiator: instead of a red badge you have to trust blindly, you see the specific indicators, from sender domain age to credential-harvesting link structure. The tool stores no email body content, which matters for teams with data handling obligations. The wall appears fast: 10 free scans a day is the ceiling without a paid account, and there is no API, no self-hosted option, and no inbox coverage outside Gmail and Outlook web.
Bottom line: Pick this for individual Gmail or Outlook web users who need a second opinion on suspicious mail before they click — but if your team needs bulk scanning, programmatic integration, or coverage across a mail server rather than a browser tab, Phixo has no path to offer that.

Pros
Sign in to edit- Four-layer scanning — rules engine, Safe Browsing, AI reasoning, and domain reputation checked in parallel — so a domain that passes one filter still gets caught by another, which means the convincing lookalike domain your spam filter lets through gets a second review.
- Plain-language breakdown of every warning sign detected, so a non-technical recipient understands the specific reason an email is flagged rather than having to trust an opaque score and guess whether to delete it.
- Sender domain age and reputation surfaced directly in the report, which means a newly registered lookalike domain — the kind used in most credential-harvesting campaigns — is visible evidence rather than a hidden signal.
- No email body storage, so teams with data handling requirements can deploy it without routing message content through a third-party server.
- 60-second install via the Chrome Web Store with Google or Microsoft sign-in, which means there is no IT provisioning step for an individual user who needs protection before the next phishing wave hits their inbox.
Cons
Sign in to edit- The free tier caps at 10 scans per day per user. A busy inbox — or a shared team mailbox — burns through that ceiling before lunch, and there is no batch or background scanning mode to work around it. Teams hit this wall on day one and either move to a paid account or stop relying on it for anything beyond occasional spot-checks.
- There is no API and no self-hosted option. Any team that needs to integrate phishing detection into a SIEM, a ticketing workflow, or an automated triage pipeline has no supported integration path. At that point the tool cannot serve the use case at all, and teams evaluating server-level or programmatic solutions look elsewhere — typically at mail gateway products or security platforms with documented API access.
- Coverage is limited to Gmail and Outlook web inside Chrome. Users on desktop mail clients, mobile apps, or any browser other than Chrome get no protection, which means a team cannot standardize on Phixo as its single phishing defense without leaving gaps across part of its user base.

Curated lists that include this category
Spam filters miss convincing lookalike domains that arrive after yesterday’s training data.
Phixo runs a scan on every inbound message inside Gmail and Outlook web. It pulls signals from rules engine flags, Google Safe Browsing, AI reasoning, domain reputation, and link checking, then returns a risk score plus a plain-English list of the exact indicators that triggered the alert.
How it works
The extension stores no email body content. It surfaces sender domain age and reputation directly in the report so users can see why a message was flagged instead of guessing from an opaque badge. The vendor states the full check completes in roughly three seconds.
Free tier and limits
Users receive ten free scans per day. Anything beyond that requires a paid account. There is no API and no self-hosted option.
Who it is for / who should skip it
Phixo suits Gmail and Outlook web users who want quick phishing checks and clear explanations alongside the score. Teams that need more than ten scans daily, batch processing, or integration into SIEM or ticketing systems should skip it because the free ceiling and lack of API close those paths immediately.
