KEEP IT

The value is the network, the data or the infrastructure. Keep paying.

A ticketing system for support organisations: conversations arrive by email, chat or form, get queued and routed with service-level rules, and are reported on for staffing and quality.

Promptfree, for everyone, and the only version there is
Do not rebuild Zendesk. Build the shared inbox with SLAs, and stop before the org chart.

STACK
- Node with Fastify, Postgres, one worker for mail polling
- IMAP in, SMTP out

THREADING, THE PART EVERYONE UNDERESTIMATES
- Match on References and In-Reply-To headers first
- Fall back to a signed ticket token in the subject as [#AB12CD], never a bare number
- Never thread on subject alone, and write that rule down with an example of why

TICKETS
- Status, priority, requester, assignee, tags
- Every message and every field change appended; nothing is ever edited in place
- Merge two tickets by writing a merge event, keeping both original threads readable

SLAs
- Defined per priority: first response and resolution targets, in business hours
- A business-hours calendar with holidays, in one timezone, documented
- Breach is computed at query time from the event log, never stored as a flag

VIEWS
- Unassigned, mine, breaching soon, and everything — as saved filters
- Sorted by SLA remaining, not by creation time

AUTO-REPLIES
- One acknowledgement per ticket, never per message, or a mail loop will find you
- Loop protection: refuse to auto-reply to an address that has sent five messages in a minute

Include a README on the IMAP setup, the threading rules and the loop protection test.

What you lose

  • Ticketing that survives a support organisation: queues, skills, SLAs and escalation
  • Email threading that copes with every broken mail client and forwarding chain
  • A help centre with versioning, permissions and multilingual content
  • Reporting that support managers use to staff shifts
  • An app ecosystem the rest of the company already integrates with

If you would rather not build

  • Chatwoot — open-source shared inbox across channels
  • Help Scout — paid, simpler, aimed at smaller teams

Why this verdict

our own opinion · changed only by a person

22/100

Verdict no at 22: email threading and business-hours SLAs are the two hard parts and the prompt handles both. It still stops well short of the product, and the reason is organisational — Zendesk is bought by support departments, and departments need reporting and routing more than they need an inbox.
