Email lookup lets you find out the identity of an email sender as well as any social media account and publicly available information on the sender. The database pools information from internet search engines, government databases, and social media platforms. Using a single search parameter – the email address – you follow a sender’s digital footprint and discover their identity. This service is especially useful for lost contacts, suspected scams, or suspicious emails. One of the applications of using emails to find publicly available information is law enforcement sex offender registries such as Community Notifications and OffenderWatch. These databases allow members of the public to find registered offenders with an email address, as compared with the National Sex Offender Registry that uses name and location as search parameters. Independent services such as Truthfinder and Manytools even let you perform background checks using an email address.
