Tracking old emails

Forgive my ignorance if this is already a thing…

Could there be an addition to the Hubspot sales tool on Outlook, etc. to allow a feature to “record” old emails OR emails you’ve received? Say someone forward me a lead and I want to record/save it for later associated with a contact. I believe this would be a great feature to add.

To do this, you can forward the email to your HubSpot portal ID # at forward.hubspot.com
