The one-sentence version#
A shared inbox (support@, sales@) is a mailbox multiple people work from, with assignment, status, and collision detection so no message is answered twice or not at all.
Why you should care#
Without structure, shared inboxes leak customers. With it, they become a measurable team workflow.
The mental model#
Think of shared inbox management as a contract between you and the mailbox providers receiving your mail. You publish or configure something they can check; they check it on every message; the result feeds their decision about where your message lands. Everything below is about making that check pass consistently.
Your first setup, step by step#
- Assign an owner to every incoming thread automatically or by rule.
- Track status: open, waiting, resolved.
- Set response-time targets and alert on breaches.
- Draft replies with AI using the team's past answers as style reference.
Words you will see#
- Mailbox provider: Gmail, Microsoft, Yahoo, Apple, and the corporate gateways that decide where mail lands.
- Authentication: proof that a message is from who it says it is (SPF, DKIM, DMARC).
- Reputation: the provider's running score of your domain and IP.
- Placement: whether a message reaches the inbox, spam, or is rejected.
Common mistakes#
- Sharing one login instead of using delegated access.
- No visibility into who replied.
Frequently asked questions#

Under a few hundred messages a week, a well-managed shared inbox works. Beyond that, ticketing adds needed structure.
