You might need to send emails to a group of contacts. To do this easily, you can create distribution lists in your contacts.
To create a distribution list in your personal gmail, do the following:
Have the list of emails you would like to add (optional but helpful for the next steps)
Go to contacts.google.com
On the top left click " + create contact" and select "create multiple contacts
A pop up appears, either paste your emails from your list or add people you want on the list
Where it says "no label" click and create a label "Distribution group Name"
Once you made sure you added the names AND created the label you want for that group, click create
* You can always add or remove emails for each label.
