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.

Yahoo has a complicated filtering setup that uses a variety of techniques to protect their users from unwanted email. They use a combination of rate-limiting and temp failing along with bulk foldering as defenses. Yahoo also uses some lists provided by Spamhaus including the PBL, SBL, and XBL.

Yahoo provides whitelisting and FBL services. For senders and ESPs to qualify for the Yahoo FBL they must sign their mail with Domain Keys or DKIM. ISPs are eligible for an IP based FBL. Whitelisting is available to senders who fill out an application and qualify.

Engagement Scoring is a way to tell which emails are the most effective.

Each email address starts at zero points and goes up and down depending on actions that occur.

Action Scoring List:

5 points for View
10 points for Click

Sender Score is computed by a third party.

We have a system for coloring IP addresses based on the sender score. Requires reputation monitoring to be turned on for those IP addresses.

Color Definitions:
Black means there is no reputation monitoring/sender score for that IP.
Green = High sender score which is good 75 or higher
Yellow = Neutral sender score with 40 to 74
Red = Poor anything under 40.

It helps give an idea which IP's are the best to mail from.

Today when sending an email campaign out the most important factor is your IP and domain reputation. In the old days, content filtering was the main method of filtering email into whether it was accepted and or if ends up in the bulk/junk/spam folder.

Now everything is based on user engagement. Meaning any action that the user does to an email message, whether it is opening the message, clicking links in the message, replying to the message, marking the email as spam, deleting the message, adding the contact to your address book, etc.

Tips for Warming up IPs and Domains.

Example sending for a 30 million account warm-up period. This is only valid if your data has little to no hard bounces. Any small amount of hard bounces can wreck ip reputation.

If you have an email forwarding set-up and you are not getting email replies. There are a couple of different options.

First, make sure you are not using any kind of filters at all on your email account and on the server level. You may have to contact your hosting company and ask if they have any kind of filtering system.

There is no limit in uploading images or documents in MCC. However, the system only accepts .htm, .html files and I highly suggest that you create the message using the online editor.

But, if you need to, you can convert your Word message into a format that the system can read. To convert the message, open up Microsoft Word and load your message. Next, go to file save and save the file as Web Page Filtered.

Now, use your newly saved message to upload into our system and you're ready to go.
