Verify your domain. We flag anyone impersonating you.
Criminals register lookalikes of your domain to send fake invoices and phishing in your name. Verify with Sender Registry and we watch for them continuously, alert you the instant one appears, and give your customers a way to confirm your genuine emails.
Verifying your main domain is free. See your lookalikes with no account needed.
Protection
We tell you the instant anyone impersonates you. We generate the likely lookalikes of your domains, watch Certificate Transparency logs for new ones being set up, and check every report on the network against your verified domains.
Reassurance
When your customers forward one of your emails to check it, and it passes authentication, they are told it genuinely is you, instead of an uncertain "we cannot confirm this sender".
The signal
Show you are a verified sender. You get a permanent public verified record and a badge you can display on your website and in your email signature.
How it works
Verify your domain. Add one DNS record we give you. We read it and confirm you control the domain, in seconds. Register every domain you send from, so we never mistake one of your own domains for an impersonation.
Confirm your identity (optional, stronger tick). Tell us who you are and we check public trademark and company registries, so your record can say you genuinely are the real brand, not just that you control the domain.
We watch continuously. New lookalikes, spoofs and typosquats of your verified domains are flagged, and you are alerted the moment a genuine impersonation appears.
Your customers can confirm you. Anyone who checks one of your genuine, authenticated emails is told it really is you, and your public verified record is there for them to see.
See who is impersonating you right now
Before you do anything else, run a free check. We will show you which lookalikes of your domain are registered and live today. No account needed.
Every object in the registry (a sender, a domain, a campaign) moves through five
stages as independent evidence builds:
UNSEENNothing reported yet.
OBSERVEDOne report exists. A single data point, not yet corroborated.
CORROBORATEDA second, independent organisation has reported the same thing.
NETWORK CONFIRMEDFive or more independent organisations agree.
VERIFIEDTen or more independent organisations, the strongest confidence level.
This is deliberately separate from Risk and Confidence. How much of the network agrees
is a different question from how dangerous something looks, or how certain we are.
How Threat DNA works
Every campaign gets scored across 8 axes: infrastructure, domain patterns, message
templates, link behaviour, attachment patterns, target industries, target roles, and
campaign velocity. All plotted as a fingerprint.
Sender Registry compares every campaign's fingerprint against every other campaign's
using cosine similarity: the same technique used to compare documents by meaning, not
just matching words. A high match (we only ever suggest one above 55% similarity) means
two campaigns that look unrelated on the surface may share real infrastructure, even
under completely different domain names.
How the Intelligence Map works
Senders, domains, URLs, attachments, campaigns, brands and suppliers all become nodes
in a shared relationship graph, built from real evidence: a sender using a domain, a
domain appearing in the same report as another domain, a report belonging to a campaign.
On a phone, we deliberately don't force a giant graph onto a small screen. Instead you
get a focused view: the object you're looking at, and everything directly connected to
it, with a tap to move to any of those connections in turn.
How push notifications work
Add Sender Registry to your home screen and turn on notifications from your account -
both free, both take under a minute. From then on, anything urgent (a payment-diversion
campaign, an executive impersonation attempt) reaches you as a real notification on your
lock screen, the same way any other app alerts you.
Every notification is sent end-to-end encrypted directly to your device - nothing is
readable in transit by anyone other than your phone.
How the QR scanner works
Open Verify Before You Act, point your camera at a QR code, and capture it. The image is
decoded and the destination it leads to is checked exactly the same way we already check
a QR code found inside a forwarded email - the same detection, just with your camera as
the front door.
You'll see whether the destination is safe, blocked, or worth a second look, with a plain
explanation either way.
How sharing to Sender Registry works
On Android, once the app is added to your home screen, "Sender Registry" simply appears
as an option in your phone's normal Share menu - the same one you'd use to send a photo
to a friend. Share a suspicious text or link straight in, review it, and submit.
On iPhone, Apple's own software doesn't allow a website to appear in the Share menu
automatically. A short, one-time setup (a free "Shortcut") gets you the same result -
after that one step, it behaves identically on both phones.
