How do I send security alert emails?

To send security alert emails safely and effectively:

1. Use a trusted email service

   • Send through your company’s mail system or a transactional email provider.
   • Make sure SPF, DKIM, and DMARC are set up so messages don’t get flagged as spam.

2. Keep the message clear and actionable Include:

   • What happened
   • When it happened
   • What the recipient should do
   • Who to contact for help

3. Avoid sensitive details in the email body

   • Don’t include passwords, full tokens, or unnecessary personal data.
   • If needed, point users to a secure portal to review details.

4. Use strong subject lines Examples:

   • Security Alert: New Login Detected
   • Action Required: Password Reset Needed
   • Alert: Suspicious Activity on Your Account

5. Verify the recipient and severity

   • Send only to the affected user, security team, or designated distribution list.
   • For high-severity incidents, use more than one channel: email + SMS + ticketing/incident system.

6. Log and monitor delivery

   • Track whether the email was delivered, opened, and acknowledged.
   • Retain logs for incident response and auditing.

7. Don’t make the alert itself look like phishing

   • Use a consistent sender address.
   • Include your organization’s contact info.
   • Link to your official domain, not shortened links or random attachments.
