Managing DNS and email security across dozens of client domains is tedious and error-prone. Email Armory gives your team free bulk tools to audit, compare, and validate DNS records, email authentication, and SSL certificates across your entire client portfolio — no per-domain pricing, no signup walls.
Digital agencies manage web hosting, DNS, and email for multiple clients. One misconfigured SPF record or expired SSL certificate can cause client email to bounce or their site to show security warnings. Catching these issues proactively — before the client notices — is what separates a good agency from a great one.
Our bulk tools let you check up to 20 domains at once. Our DNS Compare tool shows side-by-side differences when migrating hosting providers. And every tool is free with no rate limits from third-party APIs — just raw, instant results.
