As per the requirement, I need to send real-time email to user (large audience) when he/she enters in a journey.
I can do it using "API Event" .
But my question is what if there are thousands of users who registers at same time (Like black Friday sale). In this case , Is the api Event is the right choice to go with it? Journey will work in this case?
Is there any other option I use to send real time emails (1:1 communication) to large number of subscribers same time?
