You work with a list provider to find and purchase a list of names and email addresses based on demographic and/or psychographic information. For example, you might purchase a list of 50,000 names and email addresses of people who live in Minnesota and don't have children. There are several sustainable ways to use email marketing to grow your business. This isn't one of them.
Buying email lists doesn't just damage your deliverability and brand reputation -- it can also put your email account at risk. Email clients like Gmail, Yahoo!, and Outlook don't want to be associated with accounts that recipients repeatedly flag as spam. Email service providers like AWeber go as far as immediately closing your account if it suspects you're sending unwanted content.
Dynamic segmentation – As alluded to earlier, you can’t just send out a generic message to everyone on your list. While basic demographic data can be used to segment your list, that’s far from taking the dynamic approach. Automation tools can help you segment your list as they go through the funnel, allowing you to send personalized messaging depending on their actions and behaviors.
