I take the rule of thumb that hotmail/outlook.com does not like more than 20% volume changes day over day and week over week. Subscribe to the SNDS, and if you see your IPs in the yellow, stop ramping up. All the other mailbox providers follow same rules more or less, but this gives you a fair control of your ramping up.
