I assume the original thinking of NOT showing the user’s signature is that Conversations may be different than email exchanges with a contact directly (from the contact, deal or ticket). That’s a really BAD assumption considering the conversations reply come from the group/generic email (e.g., sales@example.com) without ANY indication of the human (i.e., HubSpot user) sending the message.
Ironically, it’s much less important to have a signature when sending a personal email (from a user’s email address) from a contact, deal or ticket. At least in those scenarios, the recipient would see their name in the from address. Messages sent from the conversations email address (e.g., sales@example.com) without a signature feel very robotic, and will NOT encourage true “conversation”.
FIX THIS, please!
