Thanks for your response and providing the links. Based on your answer, it seems we have the option of running email automations in HubSpot. I have two more specific questions now :
Firstly, can we set a property in HubSpot so that if we turn it on for an account, a pre-set email automation will be sent to them?
Secondly, if it is feasible, can we do it with our Free HubSpot account?
Thanks for your help!
