Introduction
custom domain email hosting for business gives a company email addresses at its own domain, such as [email protected], instead of an address at a public email domain. If you are choosing a paid service, the important decision is not only which mailbox costs less: it is whether you need a focused email plan or a broader productivity suite. This guide compares the Titan-powered Professional Email plans and Microsoft 365 plans available through BBC Cloud’s Microsoft 365 page, explains what domain setup involves, and helps you select the option that fits your team.
You can use a domain you already own or register one before creating mailboxes. The domain and email service are related but distinct: the domain determines the part after the @ sign, while the email provider stores and delivers messages. A correctly configured domain can keep the same address even if you later change the mail provider.
At a glance
- Choose Titan when your priority is business email with straightforward storage tiers and email-focused tools.
- Choose Microsoft 365 when your team also needs Microsoft productivity apps, OneDrive, meetings, or collaboration features.
- Use a domain you own, or check availability through BBC Cloud domain registration.
Custom Domain Email Hosting for Business: What It Means
Custom-domain email hosting connects your domain to a provider that creates and manages your business mailboxes. Once the domain is verified and its DNS records point to the email service, you can create addresses such as [email protected] or [email protected]. The provider then handles the mailbox interface, storage, security tools, and delivery infrastructure included in the plan.
This is different from registering a domain alone. A domain registration reserves a name; it does not automatically mean that a mailbox has been created or that incoming mail is routed correctly. It is also different from web hosting: a company can host its website with one provider and its email with another, as long as it can manage the domain’s DNS records.
For a company comparing custom domain email hosting for business, the practical questions are: How many people need separate sign-ins? How much mailbox storage is required? Does the team need only email, or also office applications and shared work tools? Answering these first prevents paying for features the company will not use—or choosing a low-cost mailbox plan that does not cover the team’s actual needs.
Microsoft 365 vs. Titan: Which Email Service Fits Your Business?
The better fit depends on whether you want email-focused service or email combined with a productivity suite. The table below summarizes the difference using the plans and features supplied for this article.
| Consideration | Titan-powered Professional Email | Microsoft 365 |
|---|---|---|
| Main focus | Email hosting with webmail, mobile apps, calendar, and contacts; higher tiers add business productivity tools. | Business email with options that add Office apps, OneDrive storage, meetings, and collaboration features. |
| Mailbox storage shown | 10 GB, 30 GB, 50 GB, or 100 GB per user depending on tier. | 10 GB or 50 GB for the email-focused plans; the higher productivity plans list 50 GB of email storage. |
| Useful when | You want a lower-cost email-first plan or want Titan-specific tools such as AI writing, read receipts, or email campaigns at eligible tiers. | Your team already relies on Microsoft tools or wants email bundled with online or desktop productivity applications. |
| Domain | Use a domain that you own or register one and connect it to the service. | Use an existing domain or register a domain, then verify it and configure DNS. |
| How to compare cost | Compare the monthly amount per user with the storage and features each user needs. | Compare the selected plan and number of licensed users; check the checkout summary for the billing unit and term. |
Email-first choice If your team wants a mailbox, calendar, and contacts without paying for a wider office suite, start by comparing the Titan Light, Pro, Premium, and Ultra tiers. The Professional Email plans are labeled as powered by Titan and list storage per user.
Suite choice If employees need email plus Office apps, OneDrive, online meetings, or Microsoft Teams, compare the email-only and productivity plans on the Microsoft 365 business email page. The higher plans add productivity features, so compare the complete bundle rather than comparing only mailbox price.
Aliases also need a careful comparison. An alias such as [email protected] may direct messages to an existing mailbox, while a separate employee mailbox normally has its own sign-in and storage allocation. The Microsoft 365 product information lists up to 400 aliases, but review the plan terms to confirm what is included and whether an alias meets your use case.
Business Email Hosting Pricing and Plan Comparison
The monthly prices below are the plan prices supplied for this article and displayed for the respective products. Titan’s plan details specify storage per user; confirm the Microsoft licensing unit, renewal term, taxes, and any current promotion in the checkout before placing an order.

Price alone is not the total cost of a business email rollout. Estimate the number of separate users, then multiply by the per-user charge where applicable. Add domain registration if you need a new domain, and check whether the selected billing term changes the amount shown. A domain promotion may apply only to eligible plans or extensions, and taxes or registry fees can be separate. These plan details were prepared for the 2026 guide; confirm the live checkout total before ordering.
For a small team that only needs mailboxes, a Titan tier can be a lower starting-cost option. For a team that will use Microsoft applications and shared work services, a higher Microsoft 365 plan may replace several separate subscriptions. The right comparison is the annual total for the features your staff will actually use—not the cheapest number in isolation.
Before checkout
- Count separate users; do not count aliases as full mailboxes.
- Choose required storage per person and identify which team members need productivity apps.
- Check whether the plan is billed monthly or annually and what it renews at.
- Confirm domain registration, taxes, and any ICANN or registry fees in the final cart.
How to Connect a Domain to Business Email
To activate business email on a domain, you must prove control of the domain and direct its mail records to the provider. If you need a step-by-step walkthrough after choosing a plan, continue with our professional email setup guide.
Use an existing domain or find a new one
Choose a short, recognizable domain that your business can keep long term. If you already own a suitable domain, you usually do not need to transfer it just to use email; you need access to its DNS settings. If you need a new name, use the BBC Cloud domain registration page to check the available extensions and current checkout price.
Select the email plan and user count
Choose whether each employee needs a separate mailbox, then compare the storage and tools included in the plans above. For Microsoft 365, decide whether email-only is enough or the team needs the Office and cloud-storage features in a higher tier. For Titan, compare the mailbox and productivity features at Light, Pro, Premium, and Ultra.
Verify the domain in the provider dashboard
The provider will ask you to add a verification record, commonly a TXT record, to your domain’s DNS. Copy the exact host and value from the provider’s setup screen. Microsoft’s official domain setup documentation explains the verification workflow for its service.
Set the mail-routing and authentication records
Use the exact MX, SPF, DKIM, and DMARC instructions supplied for your selected product. The record names below explain the roles; the values are deliberately placeholders and must not be copied into a live DNS zone.
MX @ <mail server value supplied by your provider>
TXT @ <SPF value supplied by your provider>
TXT/CNAME <selector> <DKIM value supplied by your provider>
TXT _dmarc <DMARC policy selected for your domain>
Create mailboxes, aliases, and groups
Create the real user mailboxes first, then add role-based addresses such as sales@ or support@ as mailboxes, aliases, or shared addresses according to the plan. An alias is not automatically a separate login or separate storage allocation; check how the provider treats it before using an alias for an employee.
Test inbound and outbound delivery
Send test messages to and from external accounts, verify the mailbox on mobile and desktop, and check that your authentication records are published. Keep the previous mail service active until messages are flowing reliably and any planned migration is complete.
| DNS record | What it does | Setup reminder |
|---|---|---|
| MX | Routes incoming mail for the domain to the chosen email provider. | Use the priority and destination values supplied by the provider. |
| SPF (TXT) | Lists permitted senders for the domain. | Do not publish multiple conflicting SPF records; merge only according to the provider’s instructions. |
| DKIM (TXT or CNAME) | Lets receiving systems verify a cryptographic signature associated with outgoing mail. | Use the selector and value generated in the email admin panel. |
| DMARC (TXT) | Sets a policy for handling messages that fail authentication and can provide reports. | Choose a policy appropriate to your sending setup; do not copy a generic policy blindly. |
DNS changes can take time to appear everywhere. Follow the provider’s status checker and avoid deleting records for your website when changing email settings. If the domain is already used for a website, update only the mail-related records that the email provider identifies.
Common Buying and Setup Mistakes to Avoid
Most email problems come from comparing unlike plans or changing DNS before the new service is ready. Review these points before committing:
- Confusing a domain with a mailbox: registering a domain does not by itself create users or inboxes. Add an email plan and complete its setup.
- Buying too few user licenses: a role alias may serve a shared purpose, but each employee who needs an independent mailbox may require a separate user plan.
- Choosing a suite you will not use: the productivity plans add tools beyond email. Compare those benefits with your team’s actual workflow before paying for them.
- Changing MX records too early: first verify the domain and create the accounts; then switch mail routing according to the provider’s migration sequence.
- Publishing multiple SPF records: more than one SPF TXT record can cause authentication problems. Follow the provider’s merge instructions if the domain already sends mail from other services.
- Ignoring renewals and seat counts: check the renewal term and the number of users in the order summary, not only the introductory monthly price.
- Assuming a domain promotion applies to every extension: registration prices and eligibility can vary by TLD and term. Confirm the final price in the domain cart.
