Business Email for Two Partners or a Family Business: Who Owns What

Two people start a business and one of them registers the domain, sets up the email and holds every password. It works until it does not: a divorce, a buyout, a sudden illness, or just a holiday when the other partner cannot reset a password. The fix is not more trust; it is a setup where the business owns the email and both partners can run it. This guide is for partnerships, co-founders and family firms of any size.

Quick answer

Register the domain in the business's name with a company address as the registrant, not a person's. Make one partner the owner of the email workspace and the other an admin, so either can add, remove and reset mailboxes. Give every person their own name@ mailbox and make every shared address a group that both partners are members of. Write down who holds what, and review it once a year.

Who owns the domain

The domain is the business's most important digital asset; everything else can be rebuilt around it. Register it with the company as the registrant and a company contact address, such as admin@yourdomain.com, as the account email, and keep the registrar login in a shared password manager both partners can open. Turn on the registrar lock and two-factor authentication at the registrar; the domain hijacking guide explains both. If the domain is currently in one partner's personal registrar account, move it now, while everyone is on good terms. For a family business, the same rule applies: the domain belongs to the business, not to whoever was good with computers in 2019.

Owner and admin

In OquMail a workspace has one owner and can have admins. The owner's sign-in is protected by mandatory two-factor authentication; admins can manage domains, mailboxes and groups. Make one partner the owner, the other an admin, and keep both sign-ins in the password manager. That way a lost phone, a hospital stay or a falling-out never leaves the business unable to add a mailbox or reset a password. In a family firm with a parent and two adult children, the parent is usually the owner and both children admins.

Mailboxes and shared addresses

• A name@ mailbox for each person, including both partners, with its own password. Two people on one login is one lost phone away from locking both out, and it makes every email look like it came from the same person.
• hello@ or info@ as a group with both partners as members. Each gets a copy; either can reply; nobody has to check a second inbox.
• accounts@ as a group with both partners too. Money is the thing partners most need to both see, and a group means neither can be accidentally or deliberately left out.
• Any address a customer might write to, bookings@, sales@, support@, as a group that includes whoever handles it plus one partner. The groups guide shows the setup.
• admin@ as a real mailbox used only for the registrar, the bank, the tax authority and the software accounts, with its password in the shared manager. Not a group; account-recovery emails should not fan out to several inboxes.

Write it down

One page, kept with the partnership agreement: who the domain registrant is, where the registrar login lives, who is owner and who is admin, which addresses are groups and who is in them, where the password manager's recovery codes are, and what happens to each mailbox if a partner leaves. Partners who have this page never have the argument it prevents. Review it when anyone joins or leaves and once a year regardless.

If a partner leaves

1. The leaving partner's name@ mailbox is exported and then removed, or kept for a short period with a new password held by the remaining partner. The mail in it belongs to the business.
2. They are removed from every group the same day, and their admin or owner role is transferred to the remaining partner first if they held it.
3. Every shared password changes: registrar, bank, software, the admin@ mailbox.
4. Customers and suppliers who dealt with them get a short email from the remaining partner naming the new contact.
5. If the business itself ends, the closing a business guide takes over.

Common questions

We are married. Do we really need two mailboxes?

Yes. A shared mailbox cannot tell a customer which of you wrote, cannot be handed to a new employee without handing over both of you, and cannot survive one of you losing a phone. Two mailboxes and two groups cost nothing on the free plan.

What about a 50/50 partnership where neither wants the other to be "owner"?

The owner role is an administrative one, not a legal one. Pick by coin toss if you must, make the other partner an admin, write both in the one-page document, and note that the roles can be swapped at any time by the owner.

Our teenage children help in the business. Mailboxes for them?

If they email customers, yes, as name@ with the same rules as any employee. If they only help on site, no; the free plan has 15 mailboxes and they are best spent on people who write to the outside world.
