Hotmail

Delivering to Hotmail

Filtering decisions are based on a combination of sender reputation and email content.

Hotmail does limit the amount of mail a sender can send based on the reputation of the sender. Senders with a poor reputation may be limited to as few as 20,000 emails a day. Senders with good reputations sometimes see delivery problems, and may sometimes see Hotmail silently discard email they judge to be spam.
