Customer emails as a team, from your own address

A shared inbox such as info@ or support@ on your domain belongs to a district. The team reads together, assigns with a tap, writes internal notes and replies from your address. Anyone outside the district submits their reply for approval.

• Plan: Pro: 2 inboxes, Business: unlimited
• For: one district per inbox
• On your phone: swipe, push notifications, read offline

What you can do with shared inboxes

Your own domain

At your current email provider, you forward the address to KlangCity and set three DNS records. Emails go out from your address, signed with DKIM.

Conversations instead of a flood of emails

Emails are grouped into conversations. The view starts with “Open only”.

Clear responsibility

“I’ll take it”, “Mark as done”, “Reopen”, also for several conversations at once.

Internal notes

“Only your team sees this. Never goes to the customer.” If a reply sounds like a note, KlangCity warns you before sending.

Approval

Anyone outside the district submits their reply “For approval”. Nobody can approve their own draft. After 8 hours a reminder arrives.

20 seconds to undo

After “Send”, you have 20 seconds to take the reply back.

Snippets and signature

Save frequent answers with “Save as snippet”. The signature comes in full, short or not at all.

Sender checked

Every email shows whether the sender is verified. Unanswered requests come back to you after 24 hours.

At a glance: plan, permissions, data

As implemented in KlangCity, as of November 2026.

• Plan: Pro: 2 inboxes, more as an add-on. Business: unlimited. Basic and the Pro trial: none.
• Who can do what: The district, the owner and people on the trusted list reply directly, and so do admins by default. Other members read along if the inbox is open and write drafts for approval. Guests never.
• Receiving and sending: Our own mail server on our server in Frankfurt am Main, no external sending service. Your MX record stays as it is.
• Limits: Incoming emails up to 25 MB. Attachments count towards the organisation’s storage.
• AI: The inbox itself uses no AI. Only on click: “Order from this” sends the subject, the text without contact details and up to three pictures to the AI, and “Task from this” can use the subject for classification.
• Retention period: Adjustable from 180 days. Default: no time limit.

Works well with

• Tasks: “Task from this” creates a card with a link back to the email.
• Inventory: “Order from this” starts material planning.
• Calendar: Invitations for external guests to video calls can go out from an inbox.

Good to know

• Only with your own domain. Addresses at Gmail, GMX, web.de or Outlook.com do not work.
• You reply to incoming conversations. Writing new emails and forwarding are not available.
• Replies are plain text, without attachments.
• Contents are not end-to-end encrypted.

We would rather tell you up front what is missing. What comes next is on the roadmap.
