You bought the domains — now know exactly what you're sending from. The precise registration date, how many days it's been live, when it expires, and a warmup- readiness verdict — plus the details nobody surfaces: registry status codes, DNSSEC, DNS host, and a full MX/SPF/DKIM/DMARC audit. Pulled live from the registries, right in your browser.

WHAT THESE NUMBERS MEANREAD BEFORE YOU SEND
⏳Under 21 days = warming. Fresh domains are on probation with Google & Microsoft. Keep warmup low and cold volume near zero until the safe-volume date shown above.
🗓Watch the expiry countdown. A domain that lapses mid-campaign takes every inbox on it down instantly — and recovery is brutal. Renew anything under ~30 days out today.
🚨Status codes are the silent killers.
clientHold means the registrar suspended DNS — your domain isn't resolving and nothing delivers. Most people never think to check this.🛡Aged ≠ ready. A 2-year-old domain with no SPF/DKIM/DMARC still lands in spam. The email-readiness row shows exactly what's missing.
