And to add to that, if it supports checking for certain keywords to trigger automations, that would be great. Hoping to use it as a simple incident management system to receive alerts from monitoring systems, and close automatically when it is resolved.

Guest who are sending the Email Task List and it is creating Separate task for every Email. In the ClickUp is that possible to automatically merge all such task which are having same subject line. Because reply to Email causing multiple task and that is very cumbersome to manage.

ClickUp already does "merging" for incoming e-mails if it is a reply to an e-mail sent out of ClickUp, so the code to merge e-mails is already there. It's just a guess but I think ClickUp saves the message id of the e-mail it sends in the background so it can associate replies using the In-Reply-To header. ClickUp would simply need store the Message-Id for tasks created through incoming e-mails as well.

Or if that's a coding nightmare, maybe a even a clean up/merge feature where it scans for tasks with the same name and asks you if you want to merge the newer ones as comments to an older one with the same name.
