Northern Trail Outfitters wants to import new contacts gathered from an external web form. The entries are being collected at high frequency, potentially thousands per minutes. The data does not need to be immediately ingested into Marketing Cloud as it is used in a daily scheduled automation.
What Should be recommended?

Northern Trail Outfitters (NTO) wants to use Case data from Service Cloud as part of their current email messaging campaign. They want to import cases that indicate the customer wants someone to contact them after the case is closed. NTO tracks cases with a checkbox field called "Contact Me".

A customer wants to create a journey with the goal of making users activate their accounts within 72 h of registration. New account registrations are stored in a data extension via an API call with a Boolean field indicating whether the subscriber has activated their account. The journey should send activation reminder emails 24 and 48 h after creating an account. The user exits the journey if they activate their account.
