Email Deliverability: Why DKIM, SPF, and DMARC Matter
by Luis Guzman, Solver / Engineering Team
What are DKIM, SPF, and DMARC?
DKIM, SPF, and DMARC are specialized DNS records designed to enhance email security and deliverability. They ensure that your emails are trusted by mail servers and don’t end up in the spam folder.
- SPF (Sender Policy Framework): Verifies that your email server is authorized to send emails on behalf of your domain.
- DKIM (DomainKeys Identified Mail): Adds a digital signature to your emails, ensuring their integrity during transit.
- DMARC (Domain-based Message Authentication, Reporting, and Conformance): Combines SPF and DKIM to prevent email spoofing and provides reports on email activity.
Why are these records important?
These DNS records are crucial for several reasons:
- Protect your brand reputation: By implementing these records, you reduce the risk of email spoofing and phishing attacks using your domain.
- Ensure email deliverability: Proper configuration helps your emails land in your recipient’s inbox instead of being marked as spam.
- Build trust with customers: A secure and authenticated email enhances customer confidence in your communications.
- Receive actionable insights: DMARC provides detailed reports to help you monitor and improve your email strategy.
How do these records work?
- SPF: Lists the authorized mail servers for your domain. If an unauthorized server tries to send an email, the recipient’s server may block it.
- DKIM: Adds a cryptographic signature to the email headers. The recipient's server can verify this signature to ensure the email wasn’t altered.
- DMARC: Provides a policy for how to handle emails failing SPF and DKIM checks, ensuring only legitimate emails reach the inbox.
Why your business needs these records
Without these records, your emails are at a higher risk of being marked as spam or blocked outright. This could harm your communication with customers, disrupt business operations, and damage your brand's reputation.
