Skymem

Skymem is an email address intelligence platform that searches its database for email addresses associated with a specific domain or individual, with a particular focus on exposing email addresses that have been indexed from public web sources, forum registrations, and other online contexts. It allows reverse lookups by domain to surface all email addresses the platform has indexed for that organization.

For OSINT investigators, Skymem's domain-based email enumeration is valuable during corporate reconnaissance. Entering an organization's domain retrieves all email addresses Skymem has indexed from public web crawling — revealing staff addresses, support contacts, developer accounts from code repositories, and other corporate email addresses that are discoverable through surface web indexing.

The depth of Skymem's database means it frequently surfaces email addresses that do not appear in a simple Google search, particularly addresses found in technical documentation, mailing list archives, bug reports, or developer forums. These technical context addresses can reveal internal roles, tool usage, and organizational structure.

For individual-targeted investigations, Skymem can search by person name to retrieve known email addresses, which then serve as pivot points for breach database lookups, social media account searches, and further email intelligence gathering.

Domain enumeration via Skymem is particularly useful during due diligence investigations to establish the current scope of an organization's email presence and identify personnel who are publicly associated with the domain through their email addresses.

Skymem's database also indicates when addresses were first indexed and from what general context (forum post, web page, document), providing provenance information that helps investigators understand the circumstances under which a specific email became public.

Record the domain or name queried, the returned addresses, and the query date for case documentation.
