One of the features of Google’s Gmail is that it automatically adds to your contacts people that you’ve sent an email to, replied to, or forwarded. In a way it’s not a bad thing because it saves you the hassle, but at the same time, we imagine that some users probably want to have more control over their contacts and choose who they want to add and who they don’t.
Now that that’s done, future contacts will no longer be automatically saved, but what does that mean for those that have already been added? Those contacts will remain, which is fine if you’re okay with that, but if you want to clean house, then this is what you need to do.
Do keep in mind that this will delete all contacts stored in “Other contacts”. If there are contacts there that you do not wish you lose then make sure they are not selected. Also, keep in mind that this does not delete the emails from those contacts, only the contact addresses themselves, so the emails from those contacts will still be in your Gmail account assuming you didn’t delete them.
