Research Findings

Email aliasing gives every service a unique forwarding address. If one alias gets spammed or appears in a breach, burn it — your real address is never exposed. Prevents correlation across services. SimpleLogin (Proton-owned, 10 aliases free, $30/yr premium for unlimited + custom domains). Addy.io (open source, 10 shared-domain aliases free, $1/mo Lite removes bandwidth cap + custom domain). Both support PGP encryption of forwarded mail. Best practice: one alias per service, group by risk category (banking vs commercial vs newsletters). Don't give aliases to people — use real address for personal contacts.
