When you're new to email marketing and you hear about SPF, DKIM, and DMARC, your first instinct might be to just sweep those acronyms under the nearest rug.
But these three slightly technical terms are actually really important to help secure your campaigns and make sure your emails reach the inbox. What do they do, how do you set them up, and why are they must-haves for secure emails and real domain protection? Here's your recap.

Why SPF, DKIM, and DMARC are essential for your emails
These three protocols are the foundation of email authentication. They protect your emails, your recipients, and your sender reputation:
- SPF (Sender Policy Framework) defines which servers are allowed to send emails on behalf of your domain.
- DKIM (DomainKeys Identified Mail) adds a cryptographic signature to each message.
- DMARC (Domain-based Message Authentication, Reporting and Conformance) checks that SPF and DKIM align and enforces a policy if they don’t.
These tools help you prevent spoofing, secure your email sends, and build trust with mailbox providers.

How to configure SPF, DKIM, and DMARC step by step
- Set up SPF: add a TXT record to your domain's DNS with the IPs authorized to send your emails.
- Set up DKIM: generate a key pair, publish the public key in your DNS, and sign your messages with the private key using your email platform.
- Set up DMARC: create a TXT record that specifies your policy (none, quarantine, reject) and a return address to get alignment reports.

Security best practices for beginners
- Use verification tools to check your DNS after setup.
- Start with a DMARC policy set to none, then move to quarantine or reject based on the results.
- Keep your SPF records short and clean (no more than 10 lookups).
- Regularly review your email senders and authenticate all your sources.
