Easily send a bulk email by creating a mailing list in Google Mail.
If you frequently send an email to the same group of people on Gmail and you have found no other solution than to manually enter or copy and paste the email addresses of all the recipients, you should know that there is a simpler way to avoid this painful gymnastics.
You will not find this functionality directly within email. To create a mailing list, you will need to be cunning and go directly to Contacts, Google’s address book.
1. Go to Contacts
From your Gmail box, click on the button to display Google applications and open Contacts. It is from the Google address book that you can create a mailing list for your emails.

2. Create a label
In the left column, click Create label. Enter the name of your mailing list and confirm by clicking on Save.

3. Associate contacts with the label
Your new label should appear in the Contacts side column. This label should now be added to contacts that should be in your mailing list.
To do this, click on Contacts in the left column and select each of the contacts to be included in your distribution list by hovering over the thumbnail then checking the associated box.
Then click on the Label icon at the top of the page, select the label to associate with this group of contacts and validate by clicking on Application.

To verify that all contacts have been added to your mailing list, click on your label in the left column. You should see a list of all contacts added to the label.

4. Send an email to your mailing list
Go back to Gmail, and click on New message to start writing a new email. In the To field, type the first letters of the label corresponding to your mailing list.

Google should automatically suggest the corresponding wording, which you just have to click so that all the contacts linked to it are added to the list of recipients.
