Securing Email Deliverability: Configuring SPF, DKIM, and DMARC DNS Records
Configuring email authentication records such as DKIM, SPF, and DMARC on domain management platforms like Squarespace is essential for maintaining domain deliverability and preventing email spoofing. Misconfigured or missing records can silently cause critical transactional emails—such as password resets and system notifications—to be flagged as spam or dropped entirely by major mail providers.
SRE Best Practices for Email DNS Health
- Audit TXT Records: Routinely audit your TXT records for syntax errors or missing keys when migrating DNS management platforms.
- Monitor DNS Changes: Implement automated alerting to notify your DevOps team whenever critical DNS entries are modified or deleted.
- Maintain Continuous Visibility: Track domain configuration history alongside WHOIS details to prevent operational downtime.
