Hi @terri_kleanify, 

Welcome to the Community! Thanks for sharing your question with us! 

While there isn’t a way you can figure this out preciously via an API call, you could use the steps outlined in  our API documentation here  to get the data for the received email metric which would help you get an idea of the number of emails sent so far. Additionally, you can also figure this out manually by navigating to your Klaviyo Account > Top right button of your companys name > Account

Thanks for participating in the Community!

Thanks for confirming. I did go through the documentation and was thinking this.

While the information found there is somewhat useful, it would be more helpful to know how many were sent via flows vs. campaigns.
