When MirrorWeb detects newly-seen corporate email addresses (and other identifiers) in captured communications, it queues them as pending matches on the Identity Matching page so you can "Create or match identities for newly-detected corporate email addresses". For each pending match you can link it to an existing identity, create a new identity from it, or ignore it. You can action matches individually or select several and action them together. Ignoring matches requires identity matching write access.

Navigate to the Identity Matching page. If there are no pending matches, the page shows "No pending matches". Otherwise, the matches appear in a table with the columns Identifier, Source (the platform), and Status (Active or Inactive).

You can also reach this page from the "{count} match(es) found" link on the Identities page.

Use the search box ("Search by identifier...") and press Enter to find a match by its identifier. Use the platform dropdown to filter by Source platform (or All).

To action several matches at once, tick the checkbox on each match row (or the header checkbox to select all on the page). A badge shows how many are selected, with an X to clear the selection. The action buttons in the toolbar then apply to all selected matches.

Click the Assign matches button (or, on a single row, its assign button) to open the "Assign {count} match(es)" popover. Search for an identity ("Search for an identity..."), select it, and click Assign. On success you see "Matches assigned successfully".

If the identifier is already linked to that identity, you see an error: "Please ensure the identifier is not already associated with the selected identity."

Click the Create identity button (or its per-row equivalent) to create a new identity directly from the match. On success you see "Identity created successfully".

Click the Ignore match button to open the "Ignore {count} match(es)" popover. Choose a Reason — None, Shared inbox, Spam, or Other. If you choose Other, enter a free-text reason ("Enter a reason for ignoring this match."). Click Ignore. On success you see "Matches ignored".
