We have a similar issue. We want to use Outlook integration to send to and receive emails from leads. We don’t want to manually check “track” or “log” each time we are sending an email, depending on whether the correspondent is a lead or not. So, we always want to have tracking and logging on, BUT we don’t want new contacts to be created in CRM IF they don’t exist. This is because many of our HubSpot users are not just in Sales and so they send a ton of emails to people other than leads. But, when they DO send emails to existing leads, we want HubSpot to automatically track and log. So, it’s not enough to just blocklist our own company domain to block company confidential emails from being registered in HubSpot.
