Need help: I have an API call that fetches email account statistics for various cold email campaigns, including the sent count and bounce count for each email inbox. This data is aggregated into multiple arrays. My goal is to calculate the total statistics for each inbox across all arrays and output this data in a single array, as we are dealing with a large volume of accounts. For example: A mailbox with ID 12345 has a sent count of 7 in the first campaign (or array), and the same mailbox has a sent count of 5 in array #2, so the total sent count for mailbox 12345 would be 12.
