Go here for messages being blocked or marked as spam

Hotmail is very strict with spam complaints and they DO NOT bounce emails. They only filter to trash or junk mail. If they get only a few they will filter all email from your account. They will also filter if they detect you are sending to many non-existent accounts, since this is a characteristic of spammers.

If you use your own domain name as your FROM EMAIL ADDRESS, you can set up SPF records under your domain that will improve delivery to Hotmail. Hotmail uses senderID to accept mail and require that you set up spf records on the domain you use for your FROM email address. You will need to contact your host and ask them if they publish SPF records and are compatible with Microsoft's Sender ID initiative. Unfortunately, this is the only way to ensure delivery to Hotmail due to Hotmail's policies.

Once you have set up spf records, let Hotmail know by sending them an email at with your domain name in the body. We will then configure your Email System account accordingly.

If you are not sending from your own domain, our only recommendation is that you wait 48 hours or more between sends. Hotmail may remove your account from their filtering if they do not receive complaints within a certain span of time.
