Business Email on Your Own Domain: Options and Setup

Use an address at the domain you already own, like office@yourbusiness.com, and run it through a proper email service such as Google Workspace or Microsoft 365, in an account that belongs to your business. Then add three records to your domain, called SPF, DKIM and DMARC, so other mail systems can confirm your messages really come from you. Gmail and Yahoo both check for them, and Google says mail that isn't authenticated might be marked as spam or rejected.

A free Gmail address works on day one, which is why so many businesses start with one. The trouble comes later: it reads like a side job on a quote, and it usually sits in somebody's personal account instead of the company's.

What your own address does that Gmail can't

It matches everything else. The address on an estimate should end in the same name as the website on your truck. A customer who gets a quote from office@yourbusiness.com knows who sent it.
The business keeps the mail. When the free account belongs to an office manager who leaves, years of customer threads can leave with them. With mailboxes on your domain, you're the admin, and you decide what happens to each one.
You can add addresses as you grow. A mailbox for each tech, and an address for quotes that can be an alias landing in your own inbox.
The address outlives the provider. If you switch email services, the address stays the same, because the domain is yours. Only the settings behind it change.

How email on your domain works

Your domain is registered at a registrar, and its DNS settings tell the rest of the internet where things live. One of them, the MX record, says which company receives mail for your domain. Point it at Google and your mail goes to Google.

So the domain, the website and the email are separate pieces, often at three different companies. Our article on how hosting fits with your domain goes through that split. The one thing they share is the domain. If it lapses, the website and the email stop together, which is why the domain should be registered in your own name.

Your options for business email

Google Workspace

Gmail with your own address. If your team already uses Gmail on their phones, there's very little to learn. It comes with a shared calendar and file storage, you manage users from an admin console, and you pay per user.

Microsoft 365

Outlook with your own address and, depending on the plan, Word and Excel. It's the natural pick if your office already runs on Microsoft software. It's also paid per user.

Email that comes with hosting

Some hosting plans include mailboxes at your domain. That can be fine for one or two addresses. Before you rely on it, ask the host how good the spam filtering is and what happens to your email if you move the website elsewhere. If the mailboxes are part of the hosting plan, moving the site means moving your mail too.

For most service businesses the choice comes down to Google or Microsoft. Pick the one your crew will actually open on their phones.

Who should own the email account

Treat the email account like the domain. The business owns it, and you hold the keys.

You are the top admin. Google calls this role super admin, and Microsoft calls it global administrator. It should be you or a partner in the business, not the web designer and not an employee.
Billing goes on the business card, in the business name.
Set a recovery phone number you carry, and a recovery email that isn't at the same domain, so you can get back in if something breaks.
Helpers get their own logins. If a web person or an IT company sets things up, give them a separate admin account and remove it when the work is done.
Turn on two-step login for every account, starting with yours.
Don't delete a former employee's mailbox on their last day. Ask your provider how to keep the mail or pass it to someone who stays.

The three records that prove your mail is yours

The FTC's cybersecurity advice for small businesses explains why these records matter: email authentication "makes it a lot harder for scammers to spoof your company's email," that is, to send fake mail that looks like it came from you. The FTC tells businesses whose email uses the company's domain name to make sure their provider offers SPF, DKIM and DMARC.

All three live in your domain's DNS settings:

SPF lists the servers allowed to send mail for your domain. In the FTC's words, it "verifies that a mail server is allowed to send email for a given domain."
DKIM adds a signature to every message. The FTC says it "puts a digital signature on outgoing mail," so the receiving server can tell the message came from you and wasn't changed on the way.
DMARC checks that the address in the From line matches what SPF or DKIM confirmed. It also tells receiving servers what to do with mail that fails, from taking no action to flagging or rejecting it, and it can send you reports.

What Gmail and Yahoo require

Google's email sender guidelines cover mail sent to personal Gmail accounts, which Google defines as accounts ending in @gmail.com or @googlemail.com. Starting February 1, 2024, every sender has to meet a basic list, and senders of more than 5,000 messages a day to Gmail accounts have to meet a longer one.

For all senders, Google asks for:

SPF or DKIM set up for your sending domain
valid forward and reverse DNS records for the sending servers
TLS, the encryption used between mail servers
a spam rate below 0.3%, as measured in Google's Postmaster Tools

Senders above 5,000 a day need SPF and DKIM and DMARC. Google says the DMARC policy "can be set to none," so a policy that asks for no special action is enough. The From domain has to line up with the domain that passed SPF or DKIM, and marketing messages need a one-click unsubscribe.

Yahoo's rules for senders are close: SPF or DKIM and a spam rate below 0.3% for everyone, and for bulk senders both SPF and DKIM, a DMARC policy of at least p=none that passes, and a one-click unsubscribe. Yahoo doesn't put a number on what counts as bulk.

What this means for a service business

If you send quotes and replies from your own mailbox, you're nowhere near 5,000 messages a day, so the bulk rules aren't what you're up against. The all-senders list is. With a service like Google Workspace or Microsoft 365, the server items on that list, like encryption and reverse DNS, are the provider's job. The records on your domain are left to you or your web person.

Set up all three records anyway. It's a one-time job, and it makes your name harder to fake whether you count as a bulk sender or not.

What trips up small businesses is everything else that sends mail as your domain: the request form on your website, invoicing or booking software, a tool you use for seasonal reminders. Each one has to be covered by your SPF record or sign its mail with DKIM for your domain. If it isn't, its messages can fail the checks, and form notifications are often the first thing to land in junk. Our guide to form messages that reach your inbox covers that side.

How to check yours

Send an email from your business address to a personal Gmail account. Open it in Gmail on a computer, open the three-dot menu on the message and choose "Show original." Near the top you'll see a line each for SPF, DKIM and DMARC. You want all three to say PASS.

Setting it up without losing mail

Create the account in the business name, with you as the admin, and add the mailboxes and aliases you need.
Add the records the provider gives you at your registrar or DNS host: a verification record, the MX records, SPF, DKIM and DMARC. Turning on DKIM signing is often a separate switch in the admin settings, after the record is in place.
If you're moving from an old email service, copy the old mail across, and keep the old account until you're sure nothing is missing.
Put the new address everywhere it appears: the website, your Google Business Profile, estimates and invoices, the truck.
Send the Gmail test above, and leave the old Gmail account open for a few months with an auto-reply that gives the new address.

Your website runs on the same domain

The website is the other half of this. It should live on the same domain as your email, and its request form should reach you right away instead of sitting in a junk folder.
