Which problem book should a freelancer choose?

Question

CRM

Good afternoon, help with advice!
I run several websites, and tasks of varying degrees of complexity constantly appear. You can, of course, independently maintain a task book for projects, but I want to automate everything. I would like to have a system a la redmine (I worked with it as a user, I don’t know what’s inside).
Needs:
1. Sending tasks to the system by e-mail, with notifications
2. Ability to comment on tasks, set a flag completed, not completed
3. Ability to add under. tasks or lists of sub-tasks with checkboxes
Thanks in advance!

I conducted my tasks in the banal Outlook, then MS Project + MS TFS (both local and cloud servers) I write down all project tasks there, track the execution time. TFS in the cloud is free, a project licensed by bizspark
