Update your Google Contacts list with social media info
Just keeping a mailing list current can be a chore. "Between 2011 and 2012, 12 percent of people in the country over the age of 1 moved at least once," according to a December 2012 post at the official U.S. Census Bureau blog. That means that the address of one out of eight of your contacts need to be updated each year.
Mass mailers update their address lists with services. For example, in the U.S., the NCOALink (National Change of Address) service identifies address changes, and improves address accuracy (e.g., updating five digit postal codes to more location-specific nine digit codes). The mailer pays a fee for the service and ends up with a more accurate address list.But your Google Contacts list contains more than just people's mailing addresses. It contains phone numbers and email addresses. For professional contacts, it contains company names and job titles. All of this information can change without an address change. And it takes time to maintain.
