How to restore deleted Gmail contacts | ITProPortal.com. We've all been there. Once in a while we decide that the detritus of our lives is too much, and we go on a Spring Cleaning binge. We live in a blur of slovenliness for a time, and then we want a clean, unemcumbered life for a while. With me, that involves deleting unnecessary data on my computers. Luckily, with GMail, I only have to do it once, since everything is synced in Google's ubiquitous cloud. Sometimes, however, I go too far, and I realize that Aunt Helen's email address, and contact information, has been wiped from my computer's memory, seemingly forever. But, wait, Google's everywhereness can help. Google keeps all that deleted contact information for 30 days, and you can get it back! Aunt Helen isn't lost for all time. She is just hiding in the cloud, waiting for Google to bring her back to life. Happy, Happy.
