Can anyone here please (ASAP) recommend any good free or cheap software or services to check for valid (existing) email address accounts in a provided list of email addresses?
Free Email Verifier, unlike Dynamic Mail Validator 3 and MailList Validator, has a PHP send option which allows it to check domains that would normally be uncheckable, including hotmail and yahoo. Unfortunately, the freeware version of FMV can only verify 20 emails max per session and per hour if the PHP send option is used. AtomPark Email Verifier has a cheap monthly option, but their checking system is seemingly very broken as it reports many email address accounts as valid when they were not.
Thanks in advance for any suggestions.
