support@ without paying for another seat

Microsoft 365 lets you create a shared mailbox with no licence of its own, up to 50 GB, as long as the people using it have licensed mailboxes. Google Workspace does it with a Google Group switched into Collaborative Inbox mode. On a flat-rate host there is nothing to configure: support@ is a mailbox like any other, and the people who need it get its password or an alias into their own inbox.

Microsoft's own documentation is clear and worth reading in full. A shared mailbox "can store up to 50 GB of data without assigning a license to it", and "to access a shared mailbox, a user must have a licensed Exchange Online mailbox, but the shared mailbox doesn't require a separate license" (learn.microsoft.com, About shared mailboxes in Microsoft 365, checked 6 October 2026).

The rules follow from that. A shared mailbox "isn't intended for direct sign-in"; Microsoft tells you to block sign-in on its account and keep it blocked. It supports "a maximum of 25 users". Mail sent from it cannot be encrypted, because the mailbox has no security context of its own. Going past 50 GB needs an Exchange Online Plan 2 licence. And since only licensed users can open it, the free shared mailbox saves you one seat, not the seats of the people who read it.

For a company already on Microsoft 365 this is a good deal and the right way to run support@. It is only a bad deal if you are keeping a $7 a seat subscription mainly so that two people can share one address.

Google's answer is a Google Group with Collaborative Inbox features turned on, which a group owner or manager must set up first. If Groups is not available in your account, "ask your administrator to turn on Groups for Business" (support.google.com, Use a group as a Collaborative Inbox, checked 6 October 2026). Members can assign conversations to each other, mark them resolved, and reply as the group.

It works, and many small teams run support@ this way. What it is not is a mailbox: there is no inbox to open in a mail app, threads live in the Groups interface or arrive as copies in each member's own Gmail, and the group has no storage of its own in the way a mailbox does. Every member still needs a paid Workspace seat, so, as with Microsoft, the free part is the address, not the people.

When the host does not charge per user, the question disappears. support@ is a mailbox with its own login, its own folders and its own history, and you decide how people reach it. Two patterns cover almost everyone.

The first is a shared login: the mailbox has a password, and the people who answer support add it to their mail app or open it in webmail as a second account. Everyone sees the same inbox, replies go out as support@, and a message read by one person shows as read for the others. The second is an alias: support@ delivers a copy into each person's own mailbox, which suits a two-person team where each prefers their own inbox. You can also combine them, with support@ as a real mailbox for the history and an alias copy to whoever is on duty.

On Faivelo both are included on every plan, and support@ costs the same as hello@, billing@ and the next ten: nothing beyond the $6 a month the whole domain already pays. The trade is honest too. You give up the suite's assignment and resolution features that a Collaborative Inbox or a help desk offers; a plain mailbox is a plain mailbox.

Stay with the suite's free route if your team genuinely uses the suite: Teams and SharePoint, or Docs and Meet, are worth a seat each, and the shared mailbox or group is a free bonus on top. Move the shared addresses, and probably everything else, to a flat-rate host when the seats are bought for email alone. The Google Workspace comparison and the Microsoft 365 comparison do the arithmetic at five, ten and twenty-five people.

If you only want to move support@ and keep the rest where it is, that works as well. A second domain or a subdomain can live on the flat-rate host while the personal mailboxes stay put. Most teams find that once support@ has moved, the reason to keep paying per seat has gone with it.
