Microsoft: Hotmail has better spam protection than Gmail

In January, Microsoft showed Gmail users how to switch over their accounts to Microsoft's Hotmail. Today, Microsoft launched another volley in its war with Google's Gmail. In a new post on the Windows Live blog, Microsoft said its own research, combined with a third party study, show that Hotmail offers the best spam protection of any email service.

The third party study came from Cascade Insights. The company ran a similar study back in 2009, where it said that Gmail had the best spam protection. In the new report, Cascade Insights said that it created email addresses for Hotmail, Gmail and Yahoo Mail and posted those address on Facebook pages. blog sites and other placed on the Internet. The group also signed up for a number of web-based services with those email addresses.

The final results, which were conducted over five weeks, were that the Hotmail email addresses had spam 48.57 percent of the time , just slightly better than Gmail which had spam mail 48.88 percent of the time.

Yahoo Mail was a distant third with 58.33 percent of spam mail in the study's email accounts. In an article at the New York Times web site reporting on the study results, a representative from Yahoo disputed the methodology behind the study.

Microsoft says that its own research confirms that spam showing up in a Hotmail inbox has been greatly reduced over the past few years since the company has been implementing its SmartScreen technology. It now claims that an average Hotmail account now has spam email showing up just 3 percent of the time in the inbox.

One thing to state here is that if you use any account, either or gmail, to signup and every other website over the internet, you will get spammed with newsletters and stuff. So dont base your judgement on that. But if you have not given out your email and are still receiving junk, then it is an issue.

Having said that, hotmail allows superior handling and better control on these. The scheduled cleanup feature is awesome, in case you have not tried. Other than that, gmail does tend to put important and proper mails into junk, which i have not noticed hotmail doing. Other that than both are similar in offering.

This is all irrelevant. What difference does it make if hotmail has 100% detection and accuracy when SSL is not used by default, which makes it subject to hijacking. 3rd parties then have full access to the email account. Unfortunately I witnessed this a few days ago, accounts with credit info tied to that hotmail account were also compromised also. Good thing there was less spam!

Make sure to go into Options->Account details->Connect with HTTPS

I do not know if it is the best but Hotmail throws everything into the junk box. Even valid emails. Google does an excellent job because junk is in junk and valid is in my inbox. Even if it is the first time I received email from the valid recipient. That is why I use Gmail. Because I got tired of having to go into my Hotmail junk box for my valid emails that were junked.

I think it's pretty clear what's happening. When Google claims their e-mail service is sooo cool, everyone is OK with it but when a reliable source source claims Hotmail's spam protection is a little better, retards immediately start shouting fire and murder.
If only stupid kids weren't allowed on the Internet.

When Google claims anything about their services the opposite camp jumps in the "OMG MY PRIVACIES!!11!" wagon.

Don't delude yourself: fanboys are everywhere.

I moved away from Hotmail last year as its was filling up daily with at least 20/30 spam emails. I started off by forwarding all mail from Hotmail to Gmail. None of the spam got through and all of my email I sent myself or was sent by my friends got forwarded through to my Gmail.

I eventually moved all of my logins over to my Gmail account and around November 2011 I marked my Hotmail account to be deleted.

Not for me it doesn't. I have a Gmail i created just for signing up to pointless things and giving out willy nilly and it still has a hell of a lot less junk than my hotmail account that i've never used for anything.

oh... now i understand why i got 10x more spam into mais hotmail account than in my gmail one.
.

And i just remembered of one thing... last year i created a hotmail account for my mom to teach her how to use it... 10mins after creating it and it already had spam. (=

I personally feel hotmail and associated services is a much slicker and more unified service than gmail. Mail management is just a lot easier with hotmail. Gmail still seem very fragmented and the gui is just god damn awful!

I've had my hotmail account for longer, but I now use it specifically as a spam box. If I sign up to something then I use my hotmail address rather than my gmail address. That's partly because my hotmail account was already getting spam by that point, but also because I don't get on with hotmail's interface. Each time I've used it I've spent several minutes gliding my mouse around the page while I try and find a button like "Inbox."

I use both actively and currently, hotmail is definitely ahead of gmail. in every aspect.

and google should seriously think about changing that decade old UI.

It al depends on how you use your email account. If your email address is ... 'uncommon' enough, you will not be in the "lists" automatically, so it pretty much depends on whether your email address is publicly written somewhere OR some website you register at leaks it or something.

If you're careful enough, you won't get much spam on either platform. BUT from my own experience, hotmail has a lot of false positives (legit mail that ends up in the spam folder). In fact, when most websites have to put a disclaimer about "activation emails" on hotmail accounts, you know they're doing something wrong.

I don't like the fact that gmail blocks email. What are the chances that it blocks something that I want?

On the real, I took another look at my hotmail last week and it's really good. It does a lot of stuff I like in ways GMail doesn't

Mail filters. learn how to use them properly and it really does not matter on the service...

Lies, my hotmail account which I log into once a month because I use Gmail as my primary gets hammered. Even my clients complain about all the spam they get via hotmail. What rubbish!

These numbers can vary drastically on the person.

Depending on what they sign up for and how common of a Username they used on it.

If you're getting a lot of junk mail on any service, stop signing up on dodgy sites that don't hide e-mail addresses.

This goes for hotmail and gmail and yahoo e-mail, you won't get spam if nobody knows your e-mail, stop being so coy to blame one from the other when they're all the same and shouldn't have to babysit you all when it comes to knowing what to do with your e-mail address.

Protect your e-mail just like you would other personal information and you won't have to whinge about spam.

Kick rocks who ever brought those statistics into view. I have Gmail and I would say if there was email account prone to spam, it'll be the user's fault for allowing this. I don't have any spam and only subscribe email I read on occasion with my Gmail account. I even have other Gmail accounts I don't use anymore and I check them every so often and it's always empty.

I never use my Gmail, yet receive the same amount or more spam in it then from my 3 Hotmail accounts combined, which I've had for over 10 years.

Sounds about right, I've had pretty decent results with both HotMail and GMail's filters. Once in a while one slips through but both usually does a very good job at catching them, although neither of which are my primary mail servers, light usage. Now Yahoo on the other hand I just use for forum registrations and other "temporary/junk needs" like that, check it maybe once a month, get maybe 10-20 in my inbox out of a few hundred in the spam folder, not impressed with theirs. I use a junk account like that so my real address goes spam free, never gets used publicly.. they can spam it up on the one account, I rarely look at it anyway, my main stays clean.

This has been one of the issues that has me stuck between Microsoft and Google. I switched over to Android (Google) last year because I got tired of Windows Mobile or Phone (Microsoft). I admit that I do like the Android phone, Google maps, Google+ and a whole lot of other services. However, I do not like G-mail. It is just too plain jane for me. It is full of ads with no option to get a premium account without the ads. I don't like when I go to compose a email and click on TO: another whole window opens with my contacts. Why not just create a drop down menu showing all your contacts when you click on TO:? The create a Task feature is horrible too. I should not have to go over into the right corner to create a task. What has gotten me more irritated now is the new drop down menu that Google took away after a few days and put back the black line menu across the screen again. It sucks. I have been a Hotmail plus subscriber for years and have enjoyed the way Microsoft has built up Hotmail. I hope that they start to build up the calendar and contact list part. It could really use a refresh.

haha ******** infinity! tell that to me 20+ spam a day to my Hotmail. Switched to gmail about 6 years ago and still no spam in my inbox. I also don't hide my email on forums so bots can farm all they want. Does them no good since it alllllll goes in my spam box, totally recommend anyone to switch FROM Hotmail to Gmail.

I've never got spam in my gmail inbox and I always get 1 or 2 spam emails in my hotmail.

Both account's usernames are the same.

"The company ran a similar study back in 2009, where it said that Gmail had the best spam protection"

So 2009 study was true, but now it's not... i think most of you have a problem.

I never get spam in my Gmail inbox, meanwhile its a weekly thing with my hotmail, I'm very careful when it comes to giving out either.

Oh i love you Microsoft, but i think not. My Gmail sees Spam once in a blue moon..my Hotmail one on the other hand always has a bulging Spam folder.

Never had any problems with spam on my GMail, all gets filtered nicely. And I spread my email address all over the internet without worrying about anything. ambroosv@gmail.com for example.

Anyone who prefers Hotmail over GMail is very weird or uses only simple computers. As soon as you have multiple devices you want to sync with (and it's not a Windows Phone), nothing works as well as GMail. Calendar sync that automatically refreshes external calendars, full proper contact sync, ... Only GMail truly syncs properly on almost any device. Hotmail hardly syncs properly on any device.

I call B.S. Was your professor's email address in your contacts? I doubt it. I have had maybe 2 instances where an email landed in my Spam folder instead of my Inbox. I simply added them to my contacts and never had the problem again. Whereas I couldn't safely mark emails as Spam in Hotmail without either punishing one of my actual contacts or for the label to be outright ignored when I received the same spam message a few days later.

Ive used both gmail and hotmail as primary accounts in the past few years. Gmail had a good run up until a couple years ago when I noticed the spam to my Hotmail came to grinding hault, and Gmail increased 2x-5x over the same period.

Now i forward all my Gmail to my Hotmail, and i dont know who is doing the filtering, but the spam stays on my gmail account, and is never received by Hotmail. I still get real emails forwarded.

Hotmail has definitely gotten better with the years. Definitely.
And the "My friend's been hacked" and "Report as a phishing scam" features are more than welcome.

I rarely get any spam at all, once every 4-5 months.

I originally left hotmail due to spam, however that was years ago and won't use that as a comparison for hotmail ability to block spam now.

Rubbish. Utter rubbish. I had to abandon my hotmail account for anything but junk signups to forums as it was getting inundated with spam every day (please note, I didn't use it for this purpose before abandoning it to spam).

Gmail lets one spam into my inbox ever few weeks, if that. I have not practiced any different restrictions in supplying my email address between the two services. Hotmail fills with junk and Gmail doesn't, it's as simple as that.

Both accounts were about the same age (the GMail one is a month older).

Ugh. No thanks. I don't feel the need to add another email account to my list simply because Hotmail might have changed. Too little too late. That logic is fail. I'm happy where I am.

I can say without a doubt, this is false.
My Hotmail floods with excess crap, but my Gmail is lucky to get one spam in my inbox every 3 months.

Sorry, Gmail is a hands down winner for me.

My Hotmail has 2 spam mail in my inbox in 6 months. My Gmail has none, but decided to mark my important mail as spam.

I closed my Gmail account because all I got was spam whereas with hotmail I rarely get spam. I also think Gmail looks childish. Don't know why people rate it so highly and seem so desperate to defend it all the time. Hotmail works great for me.

I would agree on this based on personal experience. My Gmail gets lot more spam than Hotmail despite the fact that I don't really use my Gmail.

Its all about being 'smart' when giving out email. I have an @hotmail email for almost a decade now, hardy received an email that was spam, cant remember.

Same. I've had one since 2001. It gets less spam than my gmail or @mac.com

waqastariq said,

I have a Gmail account that has ONLY ever been used for the signup on an Android phone, and it gets more Spam than my main hotmail account that is 10 years old.

It also isn't about the 'amount' of Spam you get, as I have another account that is my public 'whore' account, that gets a lot of Spam, yet 99% of it is shoved in the Spam folder on Hotmail, just as it should be. So even when dealing with an exposed email address that I expected to get a ton of Spam, I don't have to weed through it.

I can assume that the 'expose' of the Gmail account from the Android phone comes from Google's disclosure policy and things like Android Market App providers that are given this information. The phone was also hit with Malware a couple of times from a piggy back 'auto update' of Google software that was attached through a rooted Linux router by an ISP.

(But Google is SO awesome and secure and brilliant, and wond...FC)

I like how people are calling "bull****" based on what, their Hotmail experience from 5 years ago? lol. Microsoft updates their spam filters monthly, and has since integrated SmartScreen into Hotmail also. They've also added the "my friends been hacked" option and "report phishing" option which has probably hardened the filters quite a bit. This is perfectly believable.

No, Hotmail scans emails to figure out what kind of message it is (among other methods) but it doesn't log keywords to present you with better advertisements.

Of course it they log keywords. Not sure how else they build profiles for those who send spam. Sure MS may not scan for advertisements, but they do scan your searches, which can be just as private!

Using comparison and prediction of email content and then saving the email in an encyrpted form that Microsoft themselves cannot view is how they do this.

There is NO need to retain the email after the automated system runs a Spam check on it.

It is like this, using classic monkey analogy form:

Hotmail has a monkey that reviews emails, and the monkey marks it as Spam or not and puts it in a safe that no one but the person the email is addressed to can gain access, not the monkey or the monkey's owner.

Google has a monkey that reviews emails for Spam as well, then makes a photocopy of the email that another monkey uses to look for key words, and the photocopy of the email is then stored in a clear box without a lid that the Monkey can go back and reference at any time, and the Monkey's owner can read anytime they want.

There is quite a bit of difference between the two companies and how they treat and handle email and data in general. One protects it even from themselves, and the other keeps it and sells it to other people.

It is quite simple... Google didn't make billions of dollars by giving away search and email and Android... (Information really is power and power is money)

I switched to gmail from hotmail because it was a spamfest and all the chain mails, I may get 1 spam email every 1 or 2 years in gmail, so I see little reason to switch back.

You should take another look. Hotmail has improve a lot.

I don't understand this. Why? Why do I need to "take another look"? An email address is similar to a phone number. Why would I want to change it? Especially just to test drive a different service, which has a horrible reputation for being well...horrible.

So many people around here pushing this "new" Hotmail. No thanks. I'm 100% satisfied with Gmail and I have no desire to "try" the new Hotmail. Even looking in my Hotmail account today ****es me off beyond belief. It's littered with countless emails from people I "know", which are just spam. I have never had that problem with Gmail. I'm very careful with my email accounts and I have throw away accounts for places I'm sure I'd get spam from. But the worst thing about Hotmail is the constant spam emails from people in your own damn contact list.

Once again, no thank you. I didn't miss the Hotmail boat years ago, I voluntarily jumped off of it.

I get 2 spam mail in my Hotmail inbox in the last 6 months. Meanwhile in the same time period, I had no spam mail in my Gmail inbox, but many of my important mail went to Spam.

I get spam all the time in Hotmail. I think I have seen 2 in the 3 years I have been using it. I see about 6 or so emails a day that hit my spam mailbox in Gmail.

Based on experience I call bull**** on this too tbh.

Shaun said,
bull****!

It's not.

Probably fair to say all of them are similar and most of the time it depends on who has your email address, contacts, shops, banks, posted on websites etc. and if they fall into spam lists, sold to other companies and how real your address is, common name, first and last instead of something totally random.

I've had Gmail addresses that get the odd spam email or none while another, 60+ spam a day. Also had hotmail addresses that get no spam but others I used for anything got more spam like the Gmail one. I would say Yahoo is the worst of the three though from my experience but it's different for most as this thread will no doubt show and for the reasons I mentioned above.

If you truly want a spam free address use dummy ones that go to your real address. Hotmail and Yahoo do this. Gmail sort of does this with address+whatever@gmail.com as do Hotmail and Yahoo but easier to know your real email address with that method so best to use a dummy email that you can funnel or kill without leaving your real address open to abuse.

If you don't care about spam and want to use your normal address, Gmail and Hotmail are competent enough at telling the difference and if not you can make sure mail goes to your inbox through filters available on these services.

maybe your location, but its just not spaming something else too and it gets so worse that we got blocked my microsoft for mass spamming all our contacts, than we have to ask them to unblock, even after changing passwords, thing starts again in a while.
have stoped using hotmail long time and now asked many to do so.

honestly, its not about the no of spams you get but the best spam filtering... the spam u get in ur email is directly proportional to your stupidity!!!! Gmail has the best spam protection... also the claim is by microsft so what do u expect?

Shaun said,
bull****!

A rather convincing and insightful refuting of the article's claims...

Back in reality, Microsoft has been advancing their spam detection and screening technologies for the past few years while Google has done little in this area in comparison. Which kind of makes sense that Hotmail could be better at spotting Spam.

What magic has Microsoft done?

Well if you look at their investigative teams that have shut down Spam operations, you can see that their collection of Spam information and the techniques would be beneficial when implemented in software to predict and catch Spam better.

Microsoft also has detecting and reporting services that aggregate information from Exchange Servers, MSE, Forefront, and IE when users allow this information to be anonymously reported.

So when you add the localized predictive flags with a large general email hosting system like Live/Hotmail, it becomes pretty good at finding things that would get through the 'point prediction' technologies GMail uses.

Finding Spam by using prediction on 1 million inboxes on one domain is far less accurate than using prediction on 1 million inboxes on 10,000 domains. This is just simple statistics of probability and if Hotmail was doing 'poorly' at Spam it would be far more shocking that finding out it does well.

Corporations that use Forefront and Exchange in mission critical environments depend on Microsoft to do well at Spam reduction.

There is also the small detail that Google blindly 'encourages' Spam as it generates Ad revenue for Google when the Spam is effective, making more visitor and more hits and better advertising returns for their clients and themselves.

dont agree, i hardly use my msn.com email and only when i need to signup some id i do that, even than i dont accept any promotions and all, thus i hardly signin in months. yet i get blocked by spaming. so what i did deleted all my contacts from this email, but left mine and still i get email from it time to time .

See, I was right "the spam u get in ur email is directly proportional to your stupidity"
how do you think you get spam? its when you signup and even when you don't accept promotion they sell ur email id to external advertisers.

still1 said,

Ummmm... yeah.... not so much true, bud... I've had the same email address on Hotmail since 1996, and eventually, your email gets out there, whether it's from unscrupulous vendors who sell your address, or plain old dictionary attacks.

I also gave up hosting my own email server about 5 years ago after having to deal with the massive amounts of spam ATTEMPTS taking up my bandwidth. Once a spammer finds a domain, they will dictionary attack it like you wouldn't believe. I used to go through my connection logs on the SMTP server and you can guarantee you'll always find some jackwagon from some DSL line with an Asian telco trying to spam the crap out of you, and since they're dhcp's and not statics, there's no use trying to report them. I gave up, and finally migrated my domains to gmail's services, and haven't looked back since 2006.
