Watch emails scenario - number of operations

Hello,

I sarted using Make yesterday and I really like it.
I created a scenario where I watch some emails and save them to a database using a HTTP request with a webhook I created on my platform.

My question is: the HTTP is called only if there are new emails, but the scenario runs every minute. Even if there are no new emails, that run counts as an operation. I’m working with a free plan yet, but this can be an issue in the future.
What are your thoughts about this?

Thank you!
Daniel
