I have some bad news: Your email marketing database degrades by about 22.5% every year. Your contacts' email addresses change as they move from one company to another, opt-out of your email communication, or abandon that old AOL address they only use to fill out forms on websites.
As a marketer, it's your job to make sure you're constantly adding fresh contacts to your email marketing campaigns so you can keep your numbers moving up and to the right.
