How the default emails look in my gmail inbox
Seems like most people here just want the ability to edit the subject line. That would help. I would like it to be "Hubspot -New submission from “Contact Name” personally.
Also, being able to edit the email body text would allow the contact details to be displayed in the email preview instead of the redundant "
New submission on HubSpot Form "Lead Form" and "
Page submitted on: Page Name".
Subject line only should be free. Full body customization should be premium.
