Your business email is the master key to everything - from your hosting and domain to payment accounts and social media. If a hacker gets your email, they can reset every other password. Protecting it is not optional. Here are the 8 essential email security measures.

Access Security

  1. Strong, unique passwords - never reuse your email password anywhere else.
  2. Enable 2FA - a code from your phone blocks stolen-password attacks.
  3. Limit access - remove old devices and staff who left.
  4. Lock the account after repeated failed logins.

Domain-Level Protection

  1. SPF, DKIM and DMARC records - stop spammers from forging your domain.
  2. Encrypted connections - use secure ports for sending and receiving.
  3. Regular backups - you can recover if the account is compromised.

Safe Behaviour

  • Never click links or open attachments in unexpected emails.
  • Verify payment requests over the phone - phishing targets invoices.
  • Beware 'urgent' account warnings - go to the official site directly.
  • Do not share passwords in chat, email or calls.

Monitoring

  • Check login history for unfamiliar locations or devices.
  • Watch for unusual sent mail (a sign of compromise).
  • Set up forwarding rules carefully - hackers add hidden forwards.

Frequently Asked Questions

My email was hacked - what do I do?

Change the password immediately, sign out all devices, check for hidden forwarding rules, enable 2FA, scan for sent spam, and alert contacts. Then check linked accounts.

Does email hosting include spam protection?

Most good hosts include spam filters. Combine them with your own vigilance - filters catch junk, but the phishing test is what you do with your mouse.

Email security protects everything else you own online. Lock it down with 2FA, authenticate your domain, and stay alert to phishing - the master key stays in safe hands.
