What a business email with your own domain really costs
Two bills, two different suppliers, and mixing them up is where the surprises come from. The domain is billed yearly: as a 2026 ballpark, a .com runs $10–20 a year and a .co.uk £8–12. The mailbox is the service that stores and sends the mail, and that is where the monthly fee lives: $1–7 per person per month for mail only, $7–10 per user per month for a full suite with documents and storage.
Pricing comes in two shapes, and the difference only shows up when you hire. Per user: every new person adds a seat, so a team of five on a suite is $420–600 a year, every year, whether or not they send much mail. Per domain: $20–60 a year with unlimited mailboxes inside a daily sending limit — cheaper for two or three people, and the option most small firms never hear about because the big suites do not sell it.
A realistic one-person total: $15 of domain plus $36–84 of mailbox, so $50–100 a year. Over three years that is around $250 — the smallest fixed cost in a business that has a website. When someone offers «free email forever», ask which half is free: it is almost always receiving, which is the easy half. The domain side on its own is covered in our guide to what a domain name costs.
Forwarding, alias, mailbox: three different things sold as one
A forward takes whatever arrives at hello@yourdomain.com and drops it in the Gmail you already use. Many registrars include it free, it takes five minutes, and it works for receiving. The catch shows up when you reply: the answer leaves from your personal address and the client sees the gmail.com. Sending as your domain needs an outgoing server (SMTP) with a username and password, and that is a paid service.
An alias is another address that lands in the SAME mailbox: info@, hello@, billing@ and bookings@ at no extra cost, because no new storage is created. Most providers give them away by the dozen or unlimited. A mailbox is the thing with its own password, its own storage and its own login — the unit you actually pay for, and the only line that moves your bill.
Hence the rule that saves the most money: one mailbox per person, one alias per job. Paying for four mailboxes so one person can receive at four addresses is the most common and most expensive mistake in small-business email. And go easy on the catch-all: it accepts invented addresses and typos too, so it quietly turns into a spam magnet. Explicit aliases, one by one, age better.
Why email from a new domain goes straight to spam
A domain registered last week has no sending history, and to a spam filter «no history» reads a lot like «suspicious». Three DNS records fix that, and you set them once. SPF lists the servers allowed to send as you. DKIM signs every message so it cannot be forged in transit. DMARC tells the receiving side what to do when neither check passes, and where to send you the reports.
This is not optional polish. Since February 2024 Gmail and Yahoo require authentication from anyone sending them mail, and bulk senders —over 5,000 messages a day— also need DMARC, one-click unsubscribe and a spam complaint rate under 0.3 %. A five-person company never hits those volumes, but the filter making the decision is the same one: with no SPF or DKIM, your quote competes for the inbox against actual spam.
The first fortnight matters too: send little, reply inside real threads, and do not import a 2,000-contact list on launch day. Then run the test no provider runs for you — send a message to a Gmail address and an Outlook one, check whether it reaches the main inbox, and open the message details to confirm that SPF and DKIM both show as passed.
How many addresses you actually need
Working alone, one: yourname@yourdomain.com, with as many aliases as you like hanging off it. That is the address you use with clients, and it outperforms a generic one, because a named sender gets replies and an info@ reads like the inbox where messages go to die. An address on your own domain also survives what the free ones do not: changing phone, internet provider or mail provider.
The split that works: your name for talking to humans; one generic alias (hello@ or info@) for the website form and the Google Business listing; and a billing alias that can be handed to an accountant some day without telling anyone to update an address. That is what aliases are for — any job that may change hands should never be tied to a person's name.
In a team, one thing changes: anything shared —orders@, bookings@— should be a shared mailbox or an alias delivered into several mailboxes, never a password passed around in a chat. When someone leaves, an alias is re-pointed in a minute; a shared password has to be changed, redistributed and re-explained to everyone who used it.
The rules that apply to the mail you send (US and UK)
In the United States, CAN-SPAM applies to commercial email whether you send ten or ten thousand: accurate From and Reply-To headers, a subject line that matches the content, a valid physical postal address in the message, a visible way to opt out and that opt-out honoured within ten business days. The penalties are set per individual email, which is why a single sloppy campaign to a bought list is a bad idea rather than just bad manners.
In the United Kingdom, PECR is stricter at the front door: marketing email to individuals needs consent, with a narrow «soft opt-in» for people who already bought something similar from you and were offered a way out at the time. Business addresses at a company are treated more loosely, but you still have to identify yourself and offer an easy unsubscribe. UK GDPR sits on top of it: that mailbox holds client data.
Both sides of the Atlantic share the mistake that costs reputations: mailing fifty clients with every address visible in To or CC. Regulators treat it as disclosing personal data, and the fix costs nothing — BCC, or a sending tool that produces one message per recipient. Also get your provider's data processing terms in writing and check where the servers sit: your mail provider is a processor handling your customers' data.
Five traps in «free email included with hosting»
One: mail tied to the hosting account. If the mailbox lives in the same control panel as the site, the day you change host you are gambling with your mail and years of archive. Two: the shared IP. Your deliverability depends on the hundreds of other sites on that server; when one of them sends spam, you are the one landing in the junk folder, with nothing on your side to fix.
Three: the 1 GB quota. It sounds endless until two years of PDFs and photos fill it, and then mail simply stops arriving — sometimes without the sender getting a bounce. Four: the domain registered in the agency's name. Whoever owns the domain owns every address hanging off it, and that is the trap that genuinely costs money, because prising a domain out of someone else's account does not always work.
Five: MX records wiped during a migration. Mail and website can live in different places, and usually should. When someone moves the site and rewrites DNS without copying the mail records across, the mailbox goes quiet for hours or days — the worst of the five, because nothing bounces and nobody notices. Before any migration, ask in writing for the current MX, SPF, DKIM and DMARC records.
How we set it up
When we build a site, the domain is registered in the client's name from day one, with their details as the registrant and at a registrar that lets them move it to their own account for free. That is not paperwork: it is the difference between owning a professional email address and renting one from someone who can raise the price or vanish.
During the build we run the mailbox, with SPF, DKIM and DMARC in place from the start and verified by sending real mail to Gmail and Outlook. At handover that mailbox becomes a free forward to their personal address, inside their own account — they keep receiving on their domain without paying for a mailbox they do not need, and the domain is already theirs.
If they would rather never touch it, the managed mailbox —records kept current, archive kept safe— is part of the annual digital growth plan; what each piece costs is on the websites page and in our guide to website maintenance costs. The trades that live in their inbox have their own pages: accountants and bookkeepers, lawyers and law firms and translators and interpreters.
