What we found

  1. It publishes SPF but no DMARC record, so receivers decide for themselves what to do with email that fails.
  2. It has no robots.txt or sitemap, the two files that help search engines find its pages.
  3. The page is missing a canonical URL.
  4. The site is hosted on Hetzner Online GmbH in Germany, with a domain registered in 2014.

Email

StateRecordStatusWhat it does
SPF ?all Neutral (?all), monitoring only Lists the servers allowed to send email for the domain.
DMARC Not published Tells receivers what to do with email that fails SPF or DKIM.
DKIM Found Signs outgoing email. We check common selectors only, so a provider may use another.
MTA-STS Not deployed Stops email to the domain being downgraded to plain text in transit.
TLS-RPT Not configured Sends the owner reports of failed encrypted deliveries.

Without DMARC, receivers fall back to their own rules for email that fails SPF.

How we know

FirstSited records what new websites are built with, usually within a day of going live. Most we find ourselves, by watching public internet infrastructure for brand-new sites; the rest come from Product Hunt, Hacker News and PeerPush. We checked this one in full: its tech stack, DNS, security headers and page basics. This page is what we saw on 9 November 2026; the live site may have changed since.

Every technology below links to its own page: which other new sites launched with it. Watch any of them and get every new site that uses it as it goes live, from £15 a month.
