The aim of this research work is to develop a best optimal procedure to send the emails and get the high open rate. This research work is focused on email address verification whether it is email sender address or receiver address. The success of an email campaign depends on two major factors, Email sender address, and Email subject line. The importance of subject line is less over email sender address as it is essential to send an email to user inbox folder to start the subject line role to play. And if we get fail in pushing the email into inbox folder then subject line would not have any significance even after it is made best. Study of email sender address could be an effective area to dig out the impact of email sender address over successful email campaign. We tried to analyze the effects of email addresses over email sending by sending live emails to the users. In the email sender verification, we analyze the impact of domain, SPF, DKIM, and came up with some useful results. In email receiver verification process we developed a code to filter the email addresses of the receiver where we checked the email address for MX, disposable, duplicate, role email, and domain. After this email cleaning process, we found an extra increment in the email open and deliver rate whereas email bounce rate got decreased.
