# Email Hashes

The Hashed Email Insights Bundle will return hashed versions of known email addresses associated with the profile. The returned hashed email addresses, available in both MD5, SHA-1 and SHA-256 variations, can then be used to help link our profiles with your data. The max number of hashed email addresses that can be returned are 20. The hashes represent normalized versions of the plain-text email, both all-lowercase and all-uppercase types of normalization. Each email, we can designate it as `work`, `consumer`, `education`, `government`, or `other`. This Insights Bundle will be returned within the `emails` key in the `details` object of a Person Summary object. Should you wish to specify the hashed email variation that is returned you can use FullContact's [Hashed Email Type Filter](https://docs.fullcontact.com/docs/request-properties#hashed-email-type-filter) to specify MD5, SHA1 or SHA256.
