Docs Multiple Accounts

Unlimited Claude accounts with a custom domain

Own a domain (about $10/year) and turn on "catch-all" forwarding. Then ANY address at your domain — This email address is being protected from spambots. You need JavaScript enabled to view it., This email address is being protected from spambots. You need JavaScript enabled to view it., literally anything — lands in your inbox. Unlimited, totally distinct, never deduped. This is what power users do.

This guide is part of Set up multiple Claude accounts — the full walkthrough for getting several Claude accounts so Power Claude can rotate between them.

Reliability: Most reliable — unlimited, fully distinct

Own a domain (about $10/year) and turn on "catch-all" forwarding. Then ANY address at your domain — This email address is being protected from spambots. You need JavaScript enabled to view it., This email address is being protected from spambots. You need JavaScript enabled to view it., literally anything — lands in your inbox. Unlimited, totally distinct, never deduped. This is what power users do.

Works for rotation? The best option. Every address is on your own domain and 100% distinct — no service ever dedupes them.

Step by step

  1. Buy a cheap domain from any registrar (Cloudflare, Namecheap, Porkbun — roughly $8–12/year).
  2. Set up free email forwarding with a catch-all. Cloudflare Email Routing is free and easy: add your domain, open Email → Email Routing, and enable Catch-all address → forward to your real inbox.
  3. That's it — now This email address is being protected from spambots. You need JavaScript enabled to view it. arrives in your inbox automatically. You don't pre-create each one.
  4. Sign up for Claude using This email address is being protected from spambots. You need JavaScript enabled to view it., This email address is being protected from spambots. You need JavaScript enabled to view it., and so on. Verify from your inbox.
  5. Add each account to Power Claude's rotation. Want 20 accounts? Just invent 20 addresses.

Good to know

  • Costs a few dollars a year for the domain (forwarding itself is free with Cloudflare).
  • One-time DNS setup — the registrar's wizard walks you through it in a few clicks.

Pro tip: Use a consistent scheme like c01@, c02@, c03@ so your accounts sort neatly. With catch-all you can scale to as many accounts as you want with zero extra setup per address.
