What a group mailing list does and why you need one

A group mailing list in Gmail lets you send one email to multiple people at once by typing a single name instead of typing or pasting ten email addresses. When you create a group, Gmail stores those addresses together under a label you choose — like "Book Club" or "Project Team" — and you can add or remove people from it anytime.

The practical difference: instead of typing "sarah@email.com, james@email.com, maria@email.com" every time you want to email your running group, you type "Running Group" and Gmail fills in all three addresses. If someone's email changes or you want to add a fourth person, you update the group once and all future emails go to the new list.

Gmail calls this feature "Contact Groups" and it lives inside your Contacts, not in your email folders. This matters because the group itself is not an email address — it is a shortcut that only works when you are composing a message in Gmail on the same account where you created it.

Key Takeaways

  • Contact Groups in Gmail are stored in your Contacts app, not in email folders, and work only when composing messages in Gmail.
  • You create a group by opening Contacts, selecting multiple people, and choosing "Manage labels" to assign them to a new group name.
  • Once created, you type the group name in the "To" field when composing an email and Gmail auto-fills all addresses in that group.
  • You can edit a group anytime by opening Contacts, clicking the group name, and adding or removing individual contacts.
  • Group mailing lists work only for people sending from that Gmail account — recipients cannot see or use the group themselves.

How to create a contact group from scratch

Start by opening Gmail and clicking the Google Apps menu (the grid of nine dots in the top right corner). Select "Contacts" from the dropdown. You will land on your Contacts page, which shows all the people you have emailed or saved.

On the left side of the Contacts page, you will see a section called "Labels" with options like "Family" and "Friends". Below that is a button labeled "Create label". Click it, type the name you want for your group (like "Marketing Team" or "Dinner Party"), and press Enter. The group now exists, but it is empty.

Next, find the people you want to add. You can search for them by name using the search box at the top, or scroll through your existing contacts. Click on a person's name to open their contact card. On the right side of their card, you will see a label icon (it looks like a tag). Click it, then check the box next to the group name you just created. Repeat this for each person you want in the group.

Adding people to a group after you create it

Once your group exists, you have two ways to add more people. The first is the method above: find each person, open their contact card, click the label icon, and check your group's name.

The second way is faster if you are adding several people at once. Go to Contacts, click on your group name in the left sidebar under "Labels". You will see everyone already in the group. At the top of the list, click "Add contacts". A window opens where you can search for people by name or email. Select each person you want to add, then click "Add" at the bottom. Gmail adds them to the group when ready.

Using your group when you send an email

Open Gmail and click "Compose" to start a new message. In the "To" field, start typing the name of your group — for example, type "Mark" if your group is called "Marketing Team". Gmail will show your group name in a dropdown list below the field. Click on it, and Gmail fills in all the email addresses in that group.

You can add individual people to the same email by typing their names or addresses after the group name. You can also add a group to the "Cc" or "Bcc" field the same way. Once you have added your group and any other recipients, write your message and send it as usual.

Editing or removing people from a group

To change who is in a group, open Contacts and click the group name in the left sidebar. You will see everyone in that group listed. To remove someone, hover over their name and click the trash icon that appears. To add someone new, use the "Add contacts" button at the top as described above.

If you want to rename the group or delete it entirely, click the three-dot menu next to the group name in the left sidebar. You can choose "Rename label" to change the name, or "Delete label" to remove the group. Deleting a group does not delete the people in it from your Contacts — it only removes the group label.

Why group mailing lists work differently on your phone

If you use Gmail on your phone or tablet, you can still see and use groups you created on a computer. When you compose an email and tap the "To" field, you can search for and select a group name just like you would a person. However, you cannot create a new group or edit an existing group from the Gmail app on your phone — you have to use a computer or the full Contacts website.

If you need to manage groups on your phone, open a web browser, go to contacts.google.com, and log in with your Gmail account. You will see the full Contacts interface and can create, edit, and delete groups the same way you would on a computer.

What happens when someone in your group changes their email address

If someone in your group gets a new email address, you need to update their contact card in Gmail. Open Contacts, find their name, and click on it. Edit their email address to the new one, then save the change. The group automatically uses the new address the next time you send an email to that group.

If you remove someone's old email address entirely and replace it with a new one, Gmail will no longer try to send to the old address. If you want to keep both addresses (in case they still use the old one), you can add a second email address to their contact card instead of replacing the first one.

Frequently Asked Questions

Can I create a group mailing list on Gmail's mobile app?

No. You can use groups you already created, but you cannot create or edit groups in the Gmail app on your phone. Use a web browser and go to contacts.google.com to create or manage groups from a mobile device.

Will people in my group see each other's email addresses?

Yes, if you use the "To" field. Everyone who receives the email can see all the other recipients in the "To" line. If you want to hide addresses from each other, use the "Bcc" field instead — people in Bcc cannot see each other, though they can still see who is in the "To" and "Cc" fields.

Can I send a group mailing list to someone else so they can use it?

No. Groups are stored in your Gmail account only. If someone else wants to email the same people, they need to create their own group in their own Gmail account. You can tell them the names and addresses, but they have to set up the group themselves.

What is the maximum number of people I can add to a group?

Gmail does not publish a specific limit, but groups typically work well with dozens or even hundreds of contacts. If you are sending to more than 500 people regularly, consider using a dedicated mailing list service instead, as Gmail groups are designed for smaller, personal distribution lists.

If I delete a group by mistake, can I get it back?

Deleting a group removes the label but does not delete the contacts themselves. You can recreate the group by making a new label with the same name and re-adding the people. However, Gmail does not have an undo button for deleted groups, so you will need to remember who was in it.
