What is shared mailbox access?

You're running a support team, and every incoming ticket lands in support@yourcompany.com. Instead of one person hoarding that inbox, you want the whole team to read, reply, and track messages without stepping on each other's toes. That's shared mailbox access.

Shared mailbox access means multiple users can log in to a single email address without sharing a password. Most platforms (Google Workspace, Microsoft 365, Zoho Mail) let you grant access at the account level. Each team member signs in with their own credentials, opens the shared mailbox, and sees the same inbox.

Why this matters: permission controls let you set who can send as the shared address, who can read only, and who can delete. That prevents the chaos of three people replying to the same customer or someone accidentally nuking important emails.

Common setups: sales teams using sales@company.com, HR teams managing jobs@company.com, or support teams sharing help@company.com. Each person works from their own account but has access to the shared inbox.

But the deliverability risk nobody talks about: if your shared mailbox is also your sending domain (say, you send marketing campaigns from the same address your support team reads), you can run into authentication confusion. DKIM signatures break if the shared mailbox config doesn't match your DNS records. Best practice: use a separate address for shared access (support@) and a different one for bulk email (hello@).

What to check if you're setting one up: confirm each user has the right permission level, test that sent emails show the shared address (not the individual's), and make sure the shared mailbox isn't set up as a forwarding rule (those can mess with SPF alignment). If you're stuck, most platforms have a shared mailbox setup guide, or you can ask us if it's urgent ;)
