Thanks for your interest in our Marketing Automation:) I am Aidityo, sales manager and would like to address your query in the following way:
Now, for the free trial, you get 30,000 events API Calls free, and in your scenario, yes, you will end up exhausting all the free Event API Calls.
Also, could we get on a quick call to provide you a demo of the tool and address any other query, which you might have?
You could send me a mail at email@example.com or call @ 9910050880.
Looking forward to your response.
Sr. Sales Manager
