Intelligent system
The email verification process of QEV is designed thoughtfully, for an optimal performance. It can be thought of as two sub-processes: pre-validation and post-validation. In the pre-validation process, email list files (CSV/TXT) are verified for correctness. In post-validation, each email address in your list is checked for proof of its existence. The QuickEmailVerification system verifies email addresses against a number of different validations, starting from the RFC syntax checking to the deep level SMTP testing of user mailbox existence checking.
