What an email list is and why you'd use one
An email list in Outlook is a saved group of email addresses that you can send a single message to all at once. Instead of typing ten addresses into the "To" field, you type one list name. Outlook calls this a distribution list (in older versions) or a contact group (in newer versions). The name changed, but the function is the same.
You'd create a list if you regularly email the same set of people — your book club, your project team, your family, your volunteer group. Once the list exists, you pick it from your contacts and everyone on it gets the message. If someone's email changes, you update it once in the list, and the next message reaches the right address.
The list lives in your Outlook contacts. It does not create a separate mailbox or folder. It is purely a shortcut for addressing mail.
Key Takeaways
- Contact groups in Outlook (called distribution lists in older versions) let you send one email to multiple people by selecting the group name instead of typing each address.
- You create a contact group by opening Outlook's People or Contacts section, selecting New Contact Group, naming it, and adding members one at a time or by importing addresses.
- You can add members by typing their email address directly, selecting them from your existing contacts, or pasting a list of addresses if you format it correctly.
- Once created, the group appears in your address book and you can use it as a recipient in any email, just like a single contact.
- You can edit the group later to add or remove members, and changes take effect the next time you use the group to send mail.
Creating a contact group in Outlook on Windows
Open Outlook and go to the People tab at the bottom of the window (or click the folder icon and select Contacts if you are using an older version). This shows your contacts list.
At the top of the window, look for the New Contact Group button. Click it. A new window opens with a blank form. Type the name you want for your list in the Name field — something like "Book Club" or "Marketing Team". This is the name you will see and click when you address an email.
Below the name field, you will see an Add Members button or section. Click it. A dialog box appears with options to add people. You can add members in three ways: by selecting existing contacts from your address book, by typing in a new email address, or by pasting multiple addresses at once. Pick the method that fits what you have.
After you add all the members you want, click Save or OK (the button name depends on your Outlook version). The group is now saved in your contacts and ready to use.
Creating a contact group in Outlook on Mac
Open Outlook and click the People icon in the toolbar at the top. Your contacts appear. Look for the New Contact Group button — it usually looks like a plus sign or a group icon near the top left.
A new window opens. Type your group name in the Name field. Below that, you will see a space to add members. Click Add Member or the plus icon. A dialog appears where you can type an email address or select a contact from your list. Add each person one at a time, or paste multiple addresses if the dialog supports it.
When you are done adding members, click Save. The group is now in your contacts.
Adding members to your list
You can add members when you first create the group, or you can add them later by editing the group. To edit an existing group, go to your Contacts, find the group name, and double-click it. The group opens in edit mode.
To add a single person, click Add Member and either type their email address or select them from your contacts. To add multiple people at once, some versions of Outlook let you paste a list of addresses separated by semicolons or commas. Check your dialog box to see if a paste option appears.
If you are adding addresses by hand and you do not know them all, you can add them later. Save the group with whoever you have, then come back and add more members whenever you have their addresses. The group updates each time you save.
Using your contact group to send email
Once your group is created, sending to it works like sending to any contact. Open a new email. Click in the To field and start typing the group name. Outlook shows matching contacts, including your group. Click the group name to add it to the message.
The group name appears in the To field. When you send the message, Outlook expands the group and sends a copy to every member. Each person receives the email as if you sent it to them individually — they do not see the other recipients unless you put the group in the CC or BCC field, which works the same way.
If you want to send to the group but hide the member list from recipients, put the group name in the BCC field instead of To or CC. This is common for newsletters or announcements where you do not want people to see who else got the message.
Editing and removing members from a group
To change who is in a group, go to your Contacts, find the group name, and double-click it to open it in edit mode. You will see the list of current members. To remove someone, click their name and look for a delete or remove button — usually an X or a minus sign. To add someone new, click Add Member and follow the same steps as when you created the group.
After you make changes, click Save. The next time you use the group to send an email, it will include only the current members. People you removed will not receive future messages sent to the group, but they will have received any messages you sent before you removed them.
If you want to delete the entire group, right-click the group name in your Contacts and select Delete. This removes the group but does not affect the individual contacts — they stay in your address book.
Sharing a contact group with others
If you use Outlook with an Exchange account (common in workplaces), you can share a contact group with coworkers. The steps vary depending on your Outlook version and whether your organization allows it. In most cases, you right-click the group, select Share or Properties, and choose which people can see and use the group.
If you use Outlook with a personal email account (like Outlook.com or Gmail), contact groups are stored only on your device and cannot be shared directly through Outlook. You would need to send the list of addresses to someone else separately, and they would create their own group on their computer.
For workplace groups, check with your IT department or manager about whether sharing groups is allowed and how your organization prefers you to manage team distribution lists.
Frequently Asked Questions
Can I import a list of email addresses from a spreadsheet or text file?
Some versions of Outlook support pasting multiple addresses at once if they are separated by semicolons or commas. Copy the addresses from your spreadsheet or text file, open the group in edit mode, and try pasting them into the member field. If that does not work, you will need to add members one at a time by typing or selecting them from your contacts.
What happens if someone's email address changes after I add them to a group?
Update the contact in your address book with the new address. The next time you send to the group, Outlook uses the updated address. You do not need to edit the group itself — it pulls the current address from each contact automatically.
Can I create a group within a group?
No. Outlook does not support nested groups. You can only add individual email addresses or existing contacts to a group, not other groups. If you need to send to overlapping sets of people, create separate groups for each set.
Will people know they are part of a group when they receive an email?
Only if you put the group name in the To or CC field — then they see the group name listed as a recipient. If you put the group in the BCC field, recipients see only their own address and do not know who else got the message.
How do I know if my contact group was saved?
After you click Save, the group appears in your Contacts list with a group icon (usually a small image of multiple people). If you do not see it, go back to People or Contacts and search for the group name. If it is not there, try creating it again — the save may not have gone through.
