Everything you need to know about email deliverability.
Email deliverability is the ability of your emails to reach the recipient's inbox rather than being filtered to spam or blocked entirely. It depends on your domain's authentication setup (SPF, DKIM, DMARC), reputation, and technical configuration.
SPF (Sender Policy Framework) is a DNS record that specifies which mail servers are authorized to send emails on behalf of your domain. It helps receiving servers verify that incoming mail from your domain comes from a legitimate source.
DKIM (DomainKeys Identified Mail) adds a digital signature to your outgoing emails. Receiving servers can verify this signature against a public key published in your DNS records to confirm the email hasn't been tampered with in transit.
DMARC (Domain-based Message Authentication, Reporting & Conformance) is a policy that tells receiving servers what to do when emails fail SPF or DKIM checks. A strong DMARC policy (quarantine or reject) protects your domain from spoofing and phishing.
Start by ensuring your SPF, DKIM, and DMARC records are properly configured. Use a dedicated sending domain, warm up new email accounts gradually, and maintain a clean sender reputation by avoiding spam complaints and bounces.
