In this blog, we will explain why creating a distribution list is essential and the methods to create a Distribution List or Contact Group in MS Office 365.

Why Create a Distribution List or Contact Group?

When you create a distribution list or contact group, it makes everyday email work much easier. It applies especially when you often send messages to the same people. Some of the major reasons are mentioned below:

  • First of all, it saves your time because you can send one email to many people at once.
  • Also, everyone gets the same message together, so there is no confusion.
  • Plus, all related contacts stay in one group, which makes things easy to manage.
  • Besides that, you do not need to type email addresses again and again.
  • Because of this, sharing updates or notices with a team becomes quick.
