My sales reps send sales emails to contacts using a sales email template and sends out to a bulk list of people.
Right now, there is no functionality to see who opened that email in HubSpot lists. I can only filter by "email subject" so we know who we sent the email to, but cannot further filter by who opened it.
This functionality already exists for marketing emails, so please add this to sales emails as well.
Seconding CDiamond above - I would love to be able to filter my contact list by the number of times a contact has opened a sales email (any sales email) in a given time period.
This would allow me to find the contacts that appear interested in our content but may not have replied for some reason - very powerful.
