Rainmail
Free, instant, disposable email addresses
Estimated origin: United Kingdom
Added 12 Nov 2026
Analysed 12 Nov 2026
via Hacker News
What we found
- It sends five of the six security headers we check; the missing one is Content-Security-Policy.
- DMARC only monitors (p=none), so email spoofing this domain is still delivered.
- The page is missing Open Graph sharing tags, a canonical URL, Twitter card tags, and a favicon.
- Built with Laravel and Alpine.js, the site is hosted on The Constant Company in the United States.
- One more gap is listed further down the page.

Notes
-
Looks AI-built: few AI signals.
How much the site looks AI-generated. It is a pattern match shown for interest, not a verdict.
Which signals fired
Signal Points AI code-structure signals +10 - Analytics set tracking cookies on our visit and no consent manager was detected. UK and EU GDPR require opt-in before tracking runs, and more than 20 US states require honouring opt-out requests.
- Performance comes from one render on 12 November 2026 and will vary between visits.
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 12 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.
