Is Your Email Going to Spam?
Free DNS & Email Security Analysis
We check your 4 critical DNS records (MX, SPF, DKIM, DMARC) to see if they're configured correctly. While this won't stop all emails from going to spam or block every phishing attempt, properly configuring these records is a vital first step in securing your email and protecting your domain's reputation. Get instant results with actionable recommendations to strengthen your email security.
Understanding Email Security
What is MX?
MX (Mail Exchange) records tell the internet where to deliver your email. They point to the mail servers that handle incoming messages for your domain. Without proper MX records, you can't receive email at all. This is the foundation that must be configured first.
What is SPF?
SPF (Sender Policy Framework) is like a guest list for your domain. It tells receiving mail servers which IP addresses are allowed to send email on behalf of your domain. Without SPF, anyone can pretend to send email from your domain (spoofing). SPF must be configured before DMARC can work effectively.
What is DKIM?
DKIM (DomainKeys Identified Mail) adds a digital signature to your emails using cryptography. This proves the email came from your domain and hasn't been tampered with in transit. Think of it like a tamper-evident seal on a package. DKIM must be configured before DMARC can work effectively.
What is DMARC?
DMARC builds on SPF and DKIM to tell receiving servers what to do when an email fails authentication. It can monitor (p=none), quarantine (p=quarantine), or reject (p=reject) suspicious emails. DMARC also provides reports so you can see who's trying to spoof your domain. DMARC requires both SPF and DKIM to be properly configured first.
