Shared Mailbox vs Distribution List
What a Shared Mailbox Does
Shared mailbox vs distribution list is a choice between two team email setups. A shared mailbox is a single mailbox that several people can open, read and reply from. Mail sent to the team address is stored once, in one set of folders, and everyone with access sees the same messages. A shared mailbox suits a support inbox or an accounts address, where the team needs to see who has replied and which conversations are still open.
Because the mailbox holds the messages, its history remains when staff change. Providers usually let an administrator choose which users can open the mailbox and whether they can send as its address. Some also let team members move conversations between folders to track work. Shared mailbox features differ between business suites, so compare them when choosing a platform, as explained in Microsoft 365 vs Google Workspace.
What a Distribution List Does
A distribution list, sometimes called a group address, is an address with no mailbox of its own. Sending to the list delivers a separate copy to every member's personal mailbox. Each member keeps and manages their own copy, so the list only expands the recipients.
Distribution lists suit announcements and internal notices, such as a message to all staff about a holiday closure. They are simple to manage, because membership is just a list of addresses. However, the list keeps no shared history. Replies may go only to the person who wrote the message, depending on how the list is configured, so a reply can leave the rest of the team unaware. Check this setting before you rely on the list for discussion.
Choosing Between a Shared Mailbox and a List
Choose a shared mailbox when work must be tracked, handed over or answered by different people. Choose a distribution list when people only need to receive the same message. Some teams use both: a shared mailbox for incoming requests and a list for internal updates about the same work.
An address that forwards to one person is a different tool. For that, see email alias vs mailbox. Forwarding a team address to several people, as covered in email forwarding, can work, but it creates separate copies with no shared record, so it resembles a list without the controls.
Frequently asked questions
Can I use a shared mailbox and a distribution list together?
Yes. A common setup is a shared mailbox for requests that need tracking and a distribution list for news to the whole team. Give them different addresses, so people know which one to use for each purpose, and set the list's reply behavior so replies reach the right place.
Does everyone with access see the same messages?
In most systems, yes. Everyone with access sees the same messages and folders in a shared mailbox, which is what makes it useful for teamwork. Some systems still track read status for each user. Limit access to people who need it, because anyone with access can read every message in the mailbox.
