A business email address uses your domain after the @ symbol, such as hello@yourbusiness.ca or bookings@yourbusiness.ca. It looks more consistent than using a personal email address, and it gives your business more control over mailboxes, staff access, shared addresses, and future changes.
Before you create one, it helps to understand that your domain, website, and email can be managed separately. Your website may live on one hosting plan while email is handled by a dedicated email service. The connection between your domain and your email service is made through DNS records.
A plan for any existing email that already uses the domain
If your domain is already receiving email somewhere else, do not change MX records until the new mailboxes are ready. MX records control where incoming mail goes. Changing them too early can send messages to the wrong place or cause new messages to bounce.
Choose the Email Addresses You Need
Start with the addresses people will actually use.
For many small businesses, that means:
A personal mailbox for the owner or main contact
A shared address such as info@, hello@, or contact@
Role-based addresses such as billing@, support@, or bookings@
Use role-based addresses carefully. They are helpful for consistency, but someone still needs to monitor them. A contact address that nobody checks can create missed leads and unhappy customers.
If you have staff, give each person their own mailbox rather than sharing one password. Individual accounts are easier to secure, remove, and audit when someone leaves the business.
Pick an Email Service
Your email service is the system that stores messages, sends mail, receives mail, filters spam, and connects to apps such as Outlook or mobile mail apps.
For small businesses, Microsoft 365 is a common option because it can combine domain-based email with Outlook, calendar, contacts, Teams, and Microsoft apps, depending on the plan. The exact features depend on the subscription you choose.
Avoid treating business email as an afterthought. Email often carries quotes, invoices, login resets, customer questions, appointment requests, and vendor communication. It should be set up with ownership, security, and continuity in mind.
Add or Verify Your Domain
Most email services need to confirm that you own the domain before they let you send and receive mail using it.
Verification usually happens through a DNS record, often a TXT record. The email service gives you a specific value to add. After the record is saved, the service checks DNS and confirms the domain.
If your domain or DNS is managed through Tech Help Canada Hosting, sign in through the Tech Help Canada Hosting portal and open the domain’s DNS area. If your domain uses another DNS provider, make the change there instead.
Adding a verification TXT record usually does not move your live email by itself. The more sensitive change is the MX record, which controls where incoming mail is delivered.
Create the Mailboxes
Once the domain is verified, create the mailboxes or users you need.
For each mailbox, decide:
The email address
The display name
Who owns or monitors it
Whether it needs calendar access
Whether it should be a user mailbox, alias, or shared mailbox
What recovery and security settings should be used
An alias is another address that delivers to an existing mailbox. A shared mailbox is usually used by multiple people, such as bookings@yourbusiness.ca. A user mailbox belongs to one person.
The right mailbox type affects how people access and manage the address. If three people need to respond from one department address, a shared mailbox is usually better than passing around one login.
Update the Email DNS Records
After the mailboxes are ready, your domain needs DNS records that tell the internet how to handle email.
Common email DNS records include:
MX record for incoming mail delivery
SPF TXT record to identify approved sending services
DKIM records to help verify signed outgoing messages
DMARC TXT record to tell receiving systems how to handle failed authentication
Autodiscover or other records that help email apps configure themselves
Only add the records your email service gives you. Do not guess values from another domain or old setup.
Pay special attention to SPF. Most domains should have only one SPF record at the root domain. If you use more than one service to send email, the approved senders usually need to be combined into one SPF record.
Test Sending and Receiving
After DNS is updated, test the new address from more than one outside account.
Check:
You can receive mail from another provider
You can send mail to another provider
Replies come back to the right address
The display name looks correct
Messages are not landing in spam during normal tests
Outlook, webmail, and mobile access work if you need them
DNS changes may take time to reach every network. Some changes work quickly, while others can take longer.
Avoid These Common Mistakes
The biggest mistake is changing email DNS records before the new mailboxes exist. If incoming mail starts going to a service that has no matching mailbox, messages may bounce or disappear from the expected inbox.
Other common mistakes include:
Editing DNS at the wrong provider
Removing existing records without copying them first
Creating multiple SPF records
Forgetting shared addresses such as info@ or billing@
Failing to test forms that send mail from the website
Using one shared password for several people
Not setting up account recovery or multi-factor authentication
Before you change email records, take screenshots or notes of the existing setup. That gives you something to compare against if you need to troubleshoot.
After the Address Is Live
Update your website, contact page, business cards, invoices, social profiles, directories, appointment tools, and email signatures. Also test website forms because contact forms often depend on email settings.
If your website has a contact form, send a test message and confirm it arrives in the right inbox. Then reply to that message and make sure the customer would see the correct sender name and address.
