young_domain

The domain was registered under 30 days ago

The registry's RDAP record puts the registration less than 30 days back — the age of a domain set up for one campaign.

risk weight: +30
dataset: rdap-registration
reads from: domain_age_days
verdict reason: none: a score-only signal

What it means

Registration facts are read for business domains only, never for free providers or burners, and cached a week. Under 30 days this weight applies; from 30 to 179 days the new_domain weight of 10 applies instead. The two are exclusive, and an older or unknown age carries nothing.

It reads from domain_age_days and comes with no verdict reason of its own: a young domain can be a perfectly real startup.

What to do

Read it with the rest: young plus no SPF plus a gibberish username is a pattern; young alone is a new company.

Abbreviated: a real answer carries all 46 fields, listed in the verify-email reference. The risk_signals entry shown is the one this signal adds; the weights of every entry in the list sum to risk_score.
