Forward your company's address to your Tuti support address, so emails to it land in the Inbox. Both are in Settings → Inbox and email, under Your own address → Receiving emails, each with a copy button. On the Free plan, copy your support address from Email → Your support address on the same page. See Set up support email for the rest of the setup.

Forwarding needs a paid Proton plan.

Forward it

  1. Open Settings → All settings → Forward and auto-reply and choose Add forwarding rule.

  2. Choose your support address (like [email protected]) in Forward from, and enter your Tuti support address in Forward to.

  3. Skip the conditions with Next, then Send confirmation email.

  4. The invitation lands in your Tuti Inbox. Open it and choose Accept forwarding.

Emails forwarded outside Proton aren't end-to-end encrypted. See Proton's guide.
