Sender research & look-alike domains
Who is this, and is the domain a look-alike?
Every incoming message is checked on arrival for a domain spelt to pass as a known brand. A card above the sender's message holds a short note on who runs that domain.
In short
What is a look-alike domain?
Someone registers a domain that reads at a glance as a better known one, like paypaI.com. Its owner can make it pass DMARC and DKIM, which prove which domain sent a message, not what it resembles.

How it works
One question, about the domain
Only the domain is asked about, never the sender's name or the message. The answer is kept for later mail from it.
Near misses and borrowed letters
A domain within two edits of one of twenty brands, or a brand with something bolted on, is called out. Borrowed letters are decoded first.
The warning waits for a second sign
A near miss that passes its own DMARC and DKIM scores 18, under the warning line of 30. A disguised link or an executable attachment tips it over.
What you get
In the product today
Mixed alphabets
Latin mixed with Cyrillic or Greek in one word is flagged, whatever it imitates.
Claimed brand names
A sender calling itself PayPal from another domain is flagged too.
Background, not a verdict
The note summarises the domain. It never reads the message.
Good practice
Getting the most out of it
- 01
Read the domain
Display names cost nothing to fake. Read what follows the @.
- 02
Trust the checks first
If the note and the Sender check disagree, believe the check: only it read this message.

Where it stands
Good to know
- Names off the list
- Near misses of smaller names, like your accountant's, are caught only if they mix alphabets.
- The person
- The note describes the organisation behind a domain, never the person writing.
