I am not sure “emails send this month” is more helpful
I think it measures the past X days. If it were showing the number of emails within February, the number would not change at all. But when an email is sent, the number increases.
If the number referred to March (this month) it would not decrease because emails sent would only add up. But today I see 4 fewer emails than yesterday, when Ondrej asked. That number perfectly matches the number in the “emails sent” report for the 30 days.
