Arranging your current Gmail contacts straight into groups will save you lot of time whenever you’re composing emails to several individuals at the same time. For instance, in case you build a “Family” group, rather than dealing with an email to your mother, father, brother and sister, you are able to simply begin typing “Family” and Gmail will certainly finish the rest. Today Gmail making a couple of enhancements to contact groups which will make them simpler to create and manage.
First improvement will let’s say you have a listing of colleagues you believe you’ll wish to get in touch with once again sometime soon. Currently, you are able to paste that list into the Add to group menu when viewing your “colleagues ” group to fill or even expand it.
Second, Gmail added the ability to specify which one of your contact’s email addresses you want to use in a given group. So, for example, you can now use your friend’s personal address in your “Poker Buddies” group and that same friend’s work address in your “Coworkers” group.
