Your company domain is the foundation of your email, website, and online identity.
Treat it as a critical asset.

**Domain management best practices**

– **Own your domain.** Register it in your company’s name, with a company contact,
not an employee’s or a provider’s personal account.

– **Protect the registrar account** with MFA and a strong password

– **Enable registrar lock** to prevent unauthorized transfers

– **Turn on auto-renewal** and watch expiry dates

– **Keep contact details current,** so renewal notices reach someone

– **Document DNS records** and who manages them

– **Use reputable DNS hosting** with good availability

– **Consider DNSSEC** where supported

– **Register common variations** if brand protection matters

**Email authentication**

Configure SPF, DKIM, and DMARC to prevent spoofing and improve deliverability.

**Email migration best practices**

1. **Inventory mailboxes,** aliases, shared mailboxes, and distribution lists

2. **Clean up** old and unused data

3. **Lower DNS TTL values** a few days before the cutover so changes take effect
faster

4. **Choose a method** that fits (cutover, staged, hybrid, or IMAP-based)

5. **Pilot** with a few users

6. **Migrate in batches** and verify

7. **Switch the MX record** at a planned time, outside peak hours

8. **Reconfigure devices** and email clients

9. **Verify mail flow,** including inbound, outbound, and external senders

10. **Keep the old system** available for a safe period, and back it up

**Don’t forget**

– Auto-responders, forwarding rules, and mail-enabled applications (scanners, CRM,
websites)

– Calendars, contacts, and archives

– Email signatures and legal disclaimers

– Retention and compliance requirements

**Common mistakes**

Forgetting devices that send mail, switching DNS without testing, and losing access
to the registrar account.
