E-Mail Address Validator allows you to check that the e-mail addresses on your mailing list are valid. Sometimes people enter fake e-mail address when signing up for a newsletter. E-Mail Address Validator allows you to check the validity of these e-mail addresses by conducting tests. You can also use an exclusion list to remove e-mail addresses that begin with some words, and check the structure of an e-mail. E-Mail Address Validator is available from this website in its shareware version.
