Hello, we have some questions about klaviyo's charges; we found that when we opened an email Billing that only supports 5,000 people, and we had 10,000 customers, and we split them into two 5,000 segments, I would can email them using my 5000-only billing plan, even though they're different users; so that means, even if I don't use a 10,000-customers-only mail plan, but a 5000- customers plan, I can still Send mail to all my customers. What is the reason for this please? Is klaviyo billing plan based on the maximum number of customers that sent in a single send?
here the picture to prove this issue furtherly.
And we find we only could send 50 000 email in next month, could someone pls tell the reason?
