Four11 is one of the largest email directory services in existence, offering over seven million email listings in its database. Listings are culled from Usenet news postings, auto-registration via Internet Service Providers, and individual user submissions. Note that Four11 will delete a user's entry on request of that user, and the service displays only a limited number of items so that compiling large mailing lists for personal use is not possible.
The database can be searched by first name, last name, domain, and geographic area. One option is the use of "smart names," i.e. Bob = Robert. The results of each search are provided in a Web email form so the user can immediately send mail to the person found. A phone number lookup is offered as well, for direct queries, or linked to email query retrieval, so that the phone number of the person for whom an email address was just found can also be found. Four11 also offers an enhanced service for a fee, but basic searching is free.
