Business email often begins with one address. As a team grows, the important requirements expand to calendar sharing, account recovery, aliases, administrative control and employee offboarding. A cheap mailbox and a collaboration suite can both be reasonable choices.
List the features you will actually use
A solo professional who wants invoices sent from a branded domain may only need reliable mailboxes and forwarding. A six-person team scheduling calls, editing documents and sharing calendars may benefit from an integrated suite. An organization already standardized on particular desktop software may have different integration priorities.
Do not choose by storage alone
| Area | Evaluation question |
|---|---|
| Admin access | Can you recover accounts and remove departed employees? |
| Security | Are phishing protections and strong sign-in options available? |
| Collaboration | Will staff truly use the calendar, files and shared documents? |
| Devices | Does mail work reliably on the phones and clients staff prefer? |
| Data export | Can you migrate mailboxes, contacts and calendars later? |
Price each real mailbox and shared address
Record paid users, storage allowances, additional security tiers, archive or retention features and support expectations. Confirm whether a sales@ address can operate as an alias, group or shared mailbox without an unnecessary full account, according to the product’s current terms.
Domain setup is essential
Before switching providers, inventory the DNS records that control inbound mail and authentication. MX records route incoming messages; SPF, DKIM and DMARC help protect outgoing domain identity. Plan a gradual migration and verify that old mail remains accessible until the transfer is confirmed. Our email authentication guide explains the fundamentals.
How to compare the options
Google Workspace and Microsoft 365 offer broad collaboration ecosystems; basic hosted mailboxes focus more narrowly on email. That is a high-level distinction, not a ranking. Check current documentation for your location, required features and per-user plans. Avoid assuming that the most expensive suite automatically improves deliverability.
Test before moving the company
Set up an authorized test account, configure a sample meeting invitation, send and receive externally, inspect spam handling and practice recovery. For a real migration, preserve old credentials securely and have a rollback plan if DNS or mailbox mapping is wrong.
A six-person business: the actual cost of email
Imagine a company with six employees, one shared support address and an invoices@ address. If each staff member needs a paid mailbox at a hypothetical $7 per month, six licenses would cost $42 per month, or $504 annually. If the help address can be configured as a shared mailbox or group under the selected plan, it may not require another full license. But whether that is possible, and which staff may access it, depends on the provider’s terms.
Now add a calendar solution, basic file collaboration and an account-recovery process. A narrowly priced mailbox might require separate subscriptions for those functions. Conversely, buying a complete office suite when the team only needs email can waste money. Compare the total package that supports actual work, not just the per-mailbox headline.
The DNS setup that affects deliverability
Three records are often confused with one another. MX records direct incoming mail to the right service. SPF identifies authorized sending infrastructure for an envelope sender domain. DKIM authenticates a signature associated with the sending domain. DMARC connects authentication with the visible From domain and communicates a domain owner’s policy for failed checks.
Google’s sender guidelines require SPF or DKIM for all senders to Gmail and additional authentication requirements for bulk senders. The guidance recommends configuring SPF, DKIM and DMARC broadly. Microsoft’s custom-domain setup also explains the need for correct DNS records. Do not paste a sample SPF or DKIM value from an article into your live DNS zone: the correct entries depend on the sending providers you actually use.
Migration: the sequence that avoids disappearing mail
- Inventory every existing address, alias, group, forwarding rule and external sender such as invoicing or contact forms.
- Create new mailboxes with secure account access and appropriate recovery methods.
- Copy existing mail and calendar data through a provider-supported migration process.
- Configure authentication records and test outbound sending from a non-administrator mailbox.
- Change MX records only when ready, and verify both inbound and outbound delivery.
- Keep the previous service accessible until mail flow and data transfer have been checked.
DNS caching can delay the effect of a change. During a transition, test messages from more than one external provider and monitor both old and new systems as needed. Never assume a successful send to your own domain proves that customers can receive your messages.
What shared mailbox access should look like
The ideal support workflow avoids employees sharing one password. Where the platform supports shared mailboxes or delegated access, give each employee a personal account, grant only necessary permissions and preserve a clear offboarding process. Review whether sent messages appear consistently for colleagues and whether customers can be accidentally answered twice.
A customer may email support and later speak with another representative. That second employee should be able to find the conversation without opening a private mailbox they are not authorized to use. If the team’s needs become more complex, a support ticketing system may be more appropriate than a shared inbox. See our help desk comparison.
Security: plan for a lost phone and an employee departure
Choose an administrator recovery procedure before launch. Enable supported multi-factor authentication or passkeys, restrict domain and billing controls and define who may reset another user’s credentials. Then practice removing a test employee. Can their sessions be revoked while their necessary work emails remain accessible to the business under the provider’s retention settings?
Check whether messages are retained or deleted on account closure, how legal holds or exports work where relevant, and whether account administrators can investigate suspicious sign-ins. Do not assume that a mail provider’s spam filter replaces employee training about phishing.
Email accounts are business infrastructure
A company may treat email as a simple address until an employee leaves, a domain record changes or customer messages stop arriving. Choose business email with account recovery, authentication, shared address ownership and long-term records in mind. Storage capacity and the word “professional” on a pricing page are not enough.
Build a mailbox map before migrating: named employee accounts, shared addresses, aliases, automated system senders and mailing lists. An alias that forwards inquiries is not necessarily the same product as a shared inbox with delegated access and an audit trail. Test the precise behavior the team requires.
| Question | Reason to verify |
|---|---|
| Who owns support@? | Messages remain available when staff leave |
| How is an employee removed? | Access ends without deleting necessary business history |
| What happens during an outage? | Alternate contact and administrator recovery are available |
| Are senders authenticated? | SPF, DKIM and DMARC are configured for actual services |
| Can data be exported? | Business can migrate without losing essential records |
Choose the surrounding workflow, not only the mailbox
Google Workspace and Microsoft 365 can make sense when their documents, calendars, identity and meeting services match the business’s existing operations. A basic mailbox provider may be adequate for a small company that needs reliable custom-domain email without broader collaboration features. Neither broad suite should be purchased solely because it sounds more prestigious.
Use a pilot with one noncritical mailbox and test messages to several recipients. Check inbound routing, outbound authentication, mobile synchronization and the experience after changing a password. Keep a copy of current DNS records and a rollback plan before switching MX records. Do not delete the old service until messages and archived data have been reconciled.
A practical security baseline
Require multi-factor authentication where supported, protect administrator accounts and document how a lost phone is handled. Review shared mailbox permissions and external forwarding rules periodically. A compromised mailbox can be used to intercept invoices or impersonate the business, so email security deserves more attention than a logo on the login screen.
Provider questions worth asking in writing
| Question | Why it matters |
|---|---|
| Are aliases or shared inboxes free? | The answer changes required licenses. |
| Can we export every mailbox and calendar? | Prevents avoidable vendor lock-in. |
| What happens to departed staff? | Determines retention and account recovery. |
| Which security features require upgrades? | Prevents unexpected higher-tier costs. |
| Can our website and newsletter send from this domain? | Determines authentication and integration requirements. |
If the business mainly needs branded email for two people, test a simple mailbox provider and compare reliability. If employees collaborate constantly in documents, calendars and meetings, evaluate Google Workspace and Microsoft 365 as integrated work systems. The right choice should survive a real send/receive test, a staff offboarding drill and a three-year cost model.
