Subscription Billing Question

When someone signs up for a monthly subscription, when do they get charged (immediately, or at the start of the following month)?

If I send out a Monthly newsletter, and someone subscribes on the 10th of a month (for example), I want them to be billed at the start of the next month (since that’s when they’ll receive their first newsletter). Otherwise, they’re going to get billed for not receiving anything for that first month (and as far as I know, there’s no way to automatically send a post to new subscribers). Is that how it currently works?
