Built for people you message together, not just individually
If you find yourself typing the same list of names into the 'To' field over and over, that's usually a sign it's worth turning into a label. It saves the repeated lookup every single time.
Labels sync to your phone automatically
Because labels live on your Google account rather than a single device, any group you build in the browser shows up the same way in your phone's contacts app the next time it syncs.
Frequently Asked Questions
Can one contact belong to more than one group?
Yes, a single contact can be added to multiple labels at the same time.
Do groups sync automatically to my phone?
Yes, as long as you're signed into the same Google account, labels you create sync to your phone's contacts app.
