Without a doubt Gmail is one of the best e-mail clients around because of its functionalities and moreover the speed of the service. On the other hand, it does have a frustrating feature that whenever you send an e-mail to a new address, it will add that email address to your contact list automatically. This can be pretty annoying for the reason that the list of your contacts would start increasing with needless contacts.
Luckily, Google has introduced a new feature/option through which users can disable Gmail from adding new users in their contacts list when emailed.
To toggle this feature on tap on to the Gmail settings page and search for the option “Create contacts for auto-complete”, there will be two options from which you’ll have to check/click the option “I’ll add contacts myself” whereas by default the another option is enabled that’s why the new email addresses were added to the contacts list, but once you tick on the another option and save the settings, Gmail will not add new contacts to your contacts list except for when you will do it by yourself.
