Mail tied to a role stays with the business. Mail tied to a person leaves with them.
Plenty of working businesses still run on free email. A consultancy with four people, a repair shop, a two-person software studio, an agency that grew out of freelancing. It works, it costs nothing, and nobody wants to spend a weekend migrating.
Then something forces the question. A client asks why the invoice came from an address that does not match the company. Someone leaves and takes the inbox with them. A message that mattered turns out to have been sitting in one person’s spam folder for a month.
This is what the move actually involves, and what tends to go wrong.
What you are really fixing
Three separate problems get bundled together under the heading “we should get proper email”.
Ownership. When the business runs on an account someone created personally, that person controls it. Recovery goes to their phone. If the relationship ends badly, so does your access to years of correspondence.
Continuity. Mail tied to an individual leaves when the individual leaves. Mail tied to a role stays with the business. This is the difference between a handover and an archaeology project.
Deliverability. This is the one people underestimate. If your website’s contact form or your invoicing tool sends mail using your domain, and your domain has no authentication records published, receiving servers have no way to confirm the message is legitimate. Some file it as spam. Some reject it. You never see an error, you just get less mail than you should.
The move, step by step
Register the domain in the business name. Not in a director’s personal account, not in your web designer’s reseller account. It should be an asset of the company with a billing contact that will still exist in three years.
Decide the addresses before you create any. Attach them to roles. For most small teams, four or five is plenty: a general contact address, a billing or accounts address, a support address if you handle anything after the sale, and individual addresses for the people who deal with clients directly.
Set up authentication when you create the mailboxes, not later. SPF lists which servers may send for your domain. DKIM signs your outgoing mail so receivers can verify it was not altered. DMARC tells receivers what to do if the checks fail and lets you see who is sending mail in your name. The UK’s National Cyber Security Centre publishes small-business guidance on this among other basics, and the same advice applies wherever you operate.
Run both systems for a few weeks. Forward the old address into the new one, but send from the new one. Nothing is lost, and correspondents update their records naturally by replying to what they receive.
Tell people once, in the right places. Your website footer, your invoice template, your email signature, your social profiles, your directory listings. The update nobody remembers is the invoice template, and that is the one that matters most.
A business email service that runs on your own domain covers the mechanics of this without requiring anyone on the team to become a mail administrator.
What tends to go wrong
The invoice template. Mentioned twice deliberately. Clients pay against a document, and if that document lists an address you no longer monitor, their payment queries go nowhere.
The forms on your own website. Contact forms, booking forms, quote requests. They are usually configured by whoever built the site and then forgotten. After a domain or mail change, test every one by submitting it yourself.
Shared passwords. A single mailbox that four people log into with a password kept in a group chat is not a system, it is an incident waiting to happen. If several people need to see the same mail, use a shared or delegated mailbox rather than shared credentials.
No offboarding step. Write down what happens to accounts when someone leaves, before anyone leaves. Access removed, mail forwarded or reassigned, password changed on anything shared.
What it is reasonable to expect
Clear on cost: this is a per-user monthly fee, and for a small team it is a minor line item. What you get for it is that the business owns its own correspondence, that new staff inherit a working inbox rather than a mystery, and that your mail is authenticated so it lands where it should.
What it will not do is make anyone reply faster, or fix a slow sales process. The gain is that a category of avoidable problems stops happening.
Worth doing before you need to
The pattern with this task is that it is never urgent until it is very urgent, and by then it is usually tangled up with something worse: a departure, a dispute, or a client wondering why they never received a quote.
An afternoon spent on it while nothing is on fire is one of the better trades available to a small business.
