MarkMail is developed and hosted by
MarkLogic Corporation.
MarkMail is a free service for searching mailing list archives,
with huge advantages over traditional search engines.
It is powered by MarkLogic's Enterprise NoSQL Database. Each
email is stored internally as a document in the database.
All searches, faceted navigation, analytic calculations, and
HTML page renderings are performed by a small MarkLogic Server cluster
running against millions of messages.
