Vie Hachés: True-Private Email Aliases — Share contact, keep your identity invisible

on

Here are a couple of methods that don’t expose your “real” address (or phone) when people reply. Proper masks/aliases with reply-through that keep you cloaked.

Pick one (all hide your real address on replies)

  • Apple “Hide My Email” (iCloud+) – Random @icloud aliases you can reply from; your personal address stays private. (Apple Support)

  • Proton + SimpleLogin / Proton Pass – Create aliases that forward & support “reverse alias” replies; sender never sees your real address. (Proton)

  • Fastmail Masked Email – One-click aliases; replies go out from the alias by default. (Fastmail)

  • Firefox Relay (Premium for replying) – Masks you can reply through without revealing your inbox (mind the CC/BCC caveat). (Mozilla Support)

  • DuckDuckGo Email Protection (@duck.com) – Unlimited private addresses; replies route via duck.com, not your real address. (DuckDuckGo)

  • AnonAddy (addy.io) – Open-source aliasing with anonymous replies. (Addy)

Step-by-step (copy & do)

1) Apple “Hide My Email” (iCloud+)

  • iPhone/iPad: Settings → your name → iCloud → Hide My Email → Create New Address.

  • Compose in Mail and choose the hide-my-email address; replies keep your real address private. Deactivate any alias later. (Apple Support)

2) Proton + SimpleLogin (or Proton Pass)

  • In Proton: Settings → Addresses & Aliases to add another address or use Proton Pass / SimpleLogin to generate a random alias.

  • Reply normally; “reverse alias” relays your message so the recipient only sees the alias. You can disable or burn the alias anytime. (Proton)

3) Fastmail Masked Email

  • Fastmail web/app: Settings → Masked Email → New Masked Email.

  • Any reply to messages sent to that alias goes from the alias by default. Delete/restore as needed. (Fastmail)

4) Firefox Relay (Premium = reply)

  • Create a mask in the Relay dashboard/extension.

  • With Premium, hit reply in your normal inbox; Relay sends it without exposing your address. Don’t use CC/BCC or you’ll leak the real one. (Mozilla Support)

5) DuckDuckGo Email Protection

  • Enable in the DuckDuckGo app/extension → get you@duck.com + unlimited private addresses.

  • Reply as usual; DDG routes it via duck.com so only the alias shows. (DuckDuckGo)

6) AnonAddy (addy.io)

  • Create an alias (shared or your own domain).

  • Forwarding lands in your inbox; reply using the built-in anonymous relay so the other side never sees your real address. (Addy)

What to actually post in a public comment

Use a mask you can kill later, e.g. aix-tandem@mozmail.com (Relay), bonjour-aix@duck.com (DDG), or aix-meet@anonaddy.me. All will hide your real address on replies. (Firefox Relay)

60-second safety check

  • Turn on 2FA on your real mailbox and the alias service.

  • Keep signatures minimal (no phone, full name, school).

  • With Firefox Relay, avoid CC/BCC when replying (leaks your true address). (Firefox Relay)

  • Test: Email your alias from a different account, reply, confirm the sender only sees the alias.

Copy-paste mini-scripts

Your turn — on papote à Aix ✍️

  • A1: Post one line: “Mon alias est _____. Écrivez-moi !”

  • A2: Add a sunset date: “Je garderai cet alias jusqu’à la fin du mois.”

  • B1: Explain why you mask (spam, privacy, new group).

  • B2: Compare two services and say which fits your routine.

  • Advanced: Share your label/filters system for managing many aliases.

PS: If someone says “just DM me your real email,” smile sweetly and reply… from your alias.
