BulkVerifier

Welcome to BulkVerifier, an efficient multi-threaded application for checking e-mail addresses and domain availability. Quickly and easily verifies email addresses, huge domains and clean up your mailing / domain list. A powerful advanced bulk domain and email validation tool. BulkVerifier offers you two processing modes fast and deep. In its fast mode BulkVerifier works extremely fast being able to process mailing lists containing dozens of millions of e-mail addresses at a speed of several thousands addresses per second. This mode does not ensure the highest accuracy of checking/cleaning but is optimal by expended time and traffic and provides quite sufficient results. We recommend the fast processing mode of BulkVerifier as a high-speed tool for sifting obvious rubbish out of large mailing lists containing millions of e-mail addresses. In its deep mode (default), BulkVerifier works significantly slower but provides much more precise results. Optimal data amount for this mode is 70...100 thousand e-mail addresses. We recommend the deep processing mode of BulkVerifier as a slow but high-quality tool for checking of not very large mailing lists. BulkVerifier can process both plain list of e-mail addresses / domains where each line contains one item and files of more complex structure like CSV file where lines represents multi-field records of the same structure (i. e. containing the same fields separated with the same delimiter). For example, you can export a worksheet of an MS Excel file to check availability of e-mail addresses/domains listed there. It’s supposed that one line of an incoming file contains one e-mail address and/or one domain.

CheckMail is a powerful POP3 email checking program, which notifies you when you have received new email. It allows you to check all your email accounts for new messages and preview or delete them before downloading to your computer. CheckMail saves time and money by allowing you to delete unwanted or large emails directly from the server without downloading them. It supports custom notifications, multiple email accounts, sorting and filtering and much more. It is completely immune to viruses and other harmful email content, because it will never execute or start any attachments, scripts, programs, etc. For home offices or small businesses, CheckMail can act as a server by collecting and sending emails for many users. CheckMail is ideal for computers with permanent internet connection, because it can check for new emails at regular intervals. If you connect to the internet manually, CheckMail will ask you to connect whenever you want to check for new emails.
