On/Off toggle for auto-assigning owner when sending an email through HubSpot

When I’m prospecting, I will send emails to accounts that have no owner, as no sales rep “committed” the customer or lead yet. Howver if I send an email through hubspot, it automcatially put the account in my name making me the owner. Then I have to go back and remove myself as the owner every time because I’m simply prospecting. I wish there was a toggle in the email settings page that turns on or off whether or not an account is automatically assigned to your name if you send them an email via hubspot.
