We use ClickUp as an IT ticketing system. Users email itsupport@domainname.tld (Google Workspace). When a requester replies to an existing ticket email (subject contains “Ticket #119”, etc.), ClickUp currently creates a new task when the message is forwarded/ingested, instead of attaching the reply to the original ticket task.

Requested feature:

Add subject-based email threading so inbound emails can be automatically associated to an existing task when the subject line matches a known ticket identifier.

Acceptance criteria:

Workspace admins can define a matching rule; example:

Match pattern: Ticket #(\d+) (or similar)

Map captured number to Custom Field: Ticket #

When an inbound email is ingested (Email to List or other email ingestion address), if the subject matches an existing open task, the email content is added as a comment to that task (attachments preserved), not a new task.

If multiple tasks match, provide configurable handling (most recent, prompt, etc.).

If no match exists, create a new task (current behavior).

Optional: normalize subjects to handle common prefixes like Re:/Fwd:.

Why this matters:

This would allow ClickUp to behave more like a helpdesk system where email replies stay in one ticket, without per-ticket unique addresses or manual routing rules.
