Is there a limit of flows I can send?

Hi there,

I have the Free Klaviyo plan and a list of around 40k subscribers. The usual number of visitors it’s 1.5 to 2k per day. I want to know if my Abandoned Cart emails will be delivered to all people who triggers the flow, or if the free plan impose restrictions over the number of emails that are part of the flow.

In short, do I have to upgrade my plan to make sure the emails from the flows will be sent to people, or do I need to upgrade it only if I do campaigns?

Thanks
