Reference prices exclude VAT unless otherwise stated. Prices and service conditions may change; confirm the final quotation before registration.
- Storage: listed capacity is the total package storage, not an automatic allocation for each mailbox. Confirm individual quotas and how storage is shared.
- Included features: encrypted connections and spam filtering are listed for all four plans. Confirm message-size limits, hourly and daily sending limits, and maximum recipients per message.
- Setup scope: standard assistance may include domain verification, DNS records, mailbox creation, and basic email-client configuration. Historical transfers, large migrations, damaged mail servers, and complex DNS repairs may need a separate quotation.
- Additional costs: confirm domain registration, backup or archive storage, restoration, migration, and productivity subscriptions. The “Mail Server” plan names do not specify a dedicated physical server.
Choose a Plan for Your Team
Count employee accounts, department addresses, and expected growth. Estimate attachment volume and retention needs as well as mailbox count: a plan with more accounts may still require careful storage allocation.
- Access: verify webmail and compatibility with Outlook, Apple Mail, Thunderbird, and mobile applications.
- Recovery: ask whether backups are included, their retention period, deleted-message recovery options, and restoration fees. Synchronization is not an independent backup.
- Support: confirm support hours, channels, response targets, maintenance arrangements, availability terms, and emergency procedures.
- Migration: provide the current provider, account count, and data volume for a technical assessment and quotation.
Why Use Domain-Based Business Email?
A company-owned domain gives employees a consistent identity and helps customers recognize your business. Administrators can manage accounts and department addresses, reset access, and handle employee changes under company policy.
Use a clear naming convention such as firstname.lastname@yourcompany.com, with functional addresses such as sales@yourcompany.com and billing@yourcompany.com. Plan account ownership and handover so customer conversations remain accessible when staff responsibilities change.
Business Email vs. Free Personal Email
Address
- Business Email
- Uses the company’s domain
- Personal Free Email
- Uses the provider’s public domain
Branding
- Business Email
- Supports consistent business identity
- Personal Free Email
- Provides limited company branding
Employee account control
- Business Email
- Can be administered by the organization
- Personal Free Email
- May remain personally controlled by the user
Department addresses
- Business Email
- Can create sales, support, billing, and other addresses
- Personal Free Email
- Less suitable for centralized company ownership
Security
- Business Email
- Depends on selected provider, configuration, and policies
- Personal Free Email
- May still include strong security, but provides less domain and organizational control
Free personal email services are not automatically insecure. The main business differences are domain identity, account ownership, and organizational administration.
Which Email Service Fits Your Business?
- Email included with web hosting: may suit a small team with basic requirements. Check shared storage, sending limits, and dependence on the website server.
- Specialized email hosting: separates email from standard website hosting and focuses on mailbox management, filtering, and mail-server operation.
- Cloud productivity platforms: Google Workspace and Microsoft 365 are separate subscription products. Their subscriptions are not automatically included in these hosting plans.
- Dedicated email server: a dedicated email server offers more control over software, storage, routing, and administration, with ongoing monitoring, security, backups, and reputation management.
- Hybrid email: using several systems requires careful DNS, routing, security, and account-management planning.
Separating email from website hosting can reduce the chance that one server incident disrupts both services. Decide based on email importance, load, recovery needs, technical support, and budget.
Access Email on Your Devices
- IMAP: normally keeps messages on the server and synchronizes mailbox information across devices.
- POP3: downloads messages to an application. Whether server copies are deleted depends on client settings; it is less convenient for multi-device synchronization.
- SMTP: sends outgoing email. Use the service’s approved hostname, authentication, TLS settings, and sending limits.
- Webmail: opens your mailbox in a browser without configuring a separate application.
Protect Accounts and Authenticate Your Domain
Use strong, unique passwords, multi-factor authentication where supported, secure recovery procedures, and protected devices. Review login activity and forwarding rules, train employees to recognize suspicious messages, and avoid sharing passwords; use delegated access where supported.
- SPF: identifies servers authorized to send mail for the domain.
- DKIM: adds a digital signature that receiving systems can verify using a DNS public key.
- DMARC: builds on SPF and DKIM alignment, publishes a handling policy, and can provide authentication reports.
These controls help address direct domain spoofing but cannot stop every phishing attempt. Lookalike domains, misleading sender names, and compromised accounts still require user awareness.
Set a company policy for confidential information, device access, retention, incident reporting, and employee offboarding. Monitor quotas, review filtered messages, and confirm a recovery plan before important data is lost.
Sending Limits and Inbox Delivery
Delivery depends on domain and IP reputation, authentication, reverse DNS, sending volume, message content, recipient engagement, complaints, bounces, and recipient policies. No provider can guarantee every message will reach the primary inbox.
Keep authentication records correct, protect accounts, remove invalid recipients, and monitor delivery failures. Ordinary business mailboxes are intended primarily for person-to-person and operational communication. Bulk promotions and high-volume automated or transactional messages may require a specialized sending platform and a separate sending policy.
Setup and Handover
- Verify domain ownership, registrar and DNS access, and existing email records.
- Agree on the plan, account names, storage quotas, security settings, and service scope.
- Configure MX, SPF, DKIM, DMARC, and other required records.
- Create mailboxes and configure supported webmail or email applications.
- Test incoming and outgoing messages, external delivery, encrypted connections, and authentication.
- Hand over administrative access and user guidance according to the package.
Moving from an Existing Email Provider
Start with source access, a data inventory, and a backup plan. Prepare destination accounts, copy supported historical data, coordinate DNS changes, then test and monitor delivery after the switch.
Messages, folders, aliases, forwarding rules, contacts, calendars, and distribution lists must be assessed individually; they do not all transfer automatically. Cost and timing depend on account count, data size, source access, bandwidth, and compatibility. DNS propagation and third-party systems can affect delivery during the transition.
Frequently Asked Questions
Do I need a domain or website hosting?
You need a registered domain your organization controls. Website hosting is a separate service and is not required simply to use domain-based email.
Is storage per mailbox, and are backups included?
The plans list total package storage. Confirm mailbox quotas separately, along with backup availability, retention periods, and restoration fees.
Can Viet SEO migrate email or help with Google Workspace and Microsoft 365?
Migration is subject to source access and a technical review, with fees based on the agreed scope. Viet SEO can also assist with domain verification, DNS, account setup, migration planning, and selected administration for these separate subscription services.
What happens when an employee leaves?
Review account and device access, recovery details, and forwarding rules. Preserve required data and transfer responsibilities according to company policy before removing accounts.
Does filtering guarantee safe messages and inbox delivery?
No. Filtering and authentication reduce selected risks, but users still need security awareness. Inbox placement also depends on sending behavior and recipient policies.

24/09/2026The first step is to review the current email system, domain DNS, sending configuration, and recent delivery behavior.
Viet SEO may check areas such as:
• SPF configuration
• DKIM signing
• DMARC policy and alignment
• MX records
• Sending hostname and reverse DNS
• Domain and IP reputation
• Mail-server configuration
• TLS and authentication settings
• Sending volume and frequency
• Bounce and spam-complaint patterns
• Mailbox compromise or unusual sending activity
• Message size and attachment behavior
• Whether ordinary employee mailboxes are being used for bulk sending
If SPF, DKIM, or DMARC is missing or configured incorrectly, we can help correct the relevant DNS and mail-server settings according to the agreed scope.
We may also review whether the sending IP or domain has developed a poor reputation, whether an account has been compromised, or whether sudden sending patterns are triggering recipient filtering systems.
It is important to note that no email provider can guarantee that every message will always reach the primary inbox. Delivery decisions are also made by the recipient’s mail system and may depend on reputation, message content, user engagement, sending behavior, and anti-spam policies.
The objective is to identify technical and operational issues that may be reducing deliverability and improve the overall email configuration while keeping your existing domain-based addresses where
