Typing every contacts' email addresses individually is not the best way to send an email to everyone you know. Instead, send an email to your whole address book in Outlook. Just select all your contacts at one time and import those addresses into the message. It's even easy to remove a handful of addresses from that selection.

Instructions in this article apply to Outlook 2019, Outlook 2016, Outlook 2013, Outlook 2010, and Outlook for Office 365.

How to Send One Email to All Your Outlook Contacts

Emailing everyone in your address book is as easy as adding all your contacts to the Bcc field.

  1. Go to the Home tab and select New Email to start a new message.

  2. In the New Message window, select To.

  4. Select Bcc to add the addresses to the Bcc field.

    When emailing multiple people, take their privacy into consideration. Add their addresses to the Bcc text box to hide every address from every recipient.

Best Practices and Tips

Sending an email to many people at one time isn't a common occurrence. If you plan to do this more than once, it's faster to make a distribution list. That way, you can email one contact group that holds all of the other addresses within it.

Another good practice when sending mass emails is to address the email to a contact called undisclosed recipients. Not only is this more professional than having the email appear to be from you, but it also reinforces the idea that recipients should not Reply All.
