The market for email archives

Email is accepted by most company-data programmes, including Grepped, Mercor, Troveo, Polyshares, Pewter, Handshake AI and SimpleClosure. None prices it per message. The one disclosed bulk sale is Spirit Airlines' data, which included 100 million emails and went to Google for $10 million in a bankruptcy sale.

Notes for reading the market

Email archives come with attachments, so a single export can hold documents, spreadsheets and drawings as well as messages.

Google excludes Gmail from its Data Export tool once a Workspace subscription is cancelled or suspended, so the export window closes earlier than the deletion date.

FAQ

Frequently asked questions

01Which programmes accept company email?

Grepped, Mercor, Troveo, Polyshares, Pewter, Handshake AI and SimpleClosure all list email or Gmail and Outlook among accepted sources.

02What is a company email archive worth?

No programme prices email on its own. The only disclosed bulk sale is Spirit Airlines' data (100 million emails among other records), bought by Google for $10 million in bankruptcy.

03Can Gmail still be exported after cancelling Google Workspace?

No. Google says core service data such as Gmail, Drive and Chat is excluded from the export once the subscription is cancelled or suspended.

04How long does Microsoft keep mailboxes after a subscription ends?

After a lapse: 30 days expired, then 90 days disabled with admin-only access, then deletion. Customer content is kept at most 180 days.

05Is email priced per word?

Generic text has a reported rate of $0.001 per word, but company-data programmes price whole records per company, not email per word.
