What is Entri?

Entri is a third-party service that automates domain (DNS) configuration. Instead of asking people to log in to their registrar and edit records by hand, Entri detects the DNS provider and applies the records a service needs — such as SPF, DKIM, DMARC, or CNAME entries — through a guided, often one-click flow. It is commonly embedded by email and SaaS platforms to make domain setup faster and less error-prone.

How Entri works

When a platform integrates Entri, the user enters their domain and Entri identifies the registrar or DNS host. It then proposes the exact records the service requires and writes them automatically once the user confirms — reducing the misconfigurations that make email authentication fail. Where automatic setup is not possible, Entri falls back to clear copy-and-paste instructions.

Why domain setup matters for email

Correct DNS records are what let mailbox providers verify your mail and keep it out of spam. Whether you use a tool like Entri or configure records manually, authenticating your sending domain with SPF, DKIM, and DMARC is essential for deliverability.
