Email Marketing is all about starting with a list, continuing with data management and ending with revenue generation. Email marketing is directly pointing at the exact need of your audience and providing them the call to action. In its broadest sense, every email sent to a potential or current customer could be considered as an email to advertise your company, request business, or solicit sales or donations, and is meant to build loyalty, trust, or brand awareness. Email marketing involves a huge customer database or lists of verified email ids. Every receiving ISP is using different spam filtering techniques and some ISP’s utilize some pretty smart spam filters. So you will undoubtedly need some mail verification to get rid of bounces, improve delivery and save costs while sending email campaigns.
