Not sure who else to add to that group email? Gmail Labs now has a useful “suggest more recipients” feature that suggests contacts that you might want to include in a group email based on the people you’ve grouped together as email recipients in the past.
For example, if you often send family emails to your mother, father, husband, sister and brother, when you start composing an email to your mother and father, Gmail will suggest adding your sister, husband and brother. The feature is triggered only after you’ve added at least two recipients to the email.
To enable the feature, go to Gmail Labs and turn it on as a setting. This clever feature is just one of the many nifty innovations that has come out of Gmail Labs, including offline access, contact time zones, search suggestions, an undo button, multi-pane viewing, and many more.
