			<content:encoded><![CDATA[<img style='float: left; margin-right: 10px; border: none;' src='http://www.gravatar.com/avatar.php?gravatar_id=ea7a67d6e63a01a8a1df53853a9757bc&amp;default=http://www.spamhero.com/images/logo-avatar_90x90.gif' alt='No Gravatar' width=40 height=40/><p>Some have said that we&#8217;ll never win the fight against spam.  And  <em>they</em> probably never will.  But SpamHero is unique, even revolutionary.   We designed it from the ground up to resolve the problems that plague other spam  filtering services.  Here are the top 10 problems we saw with the other  companies in this industry:</p>
<p><strong>Mistake #1: Make bogus claims about  how accurate their filter is.<br />
</strong><br />
We tested high and low.  Most of  the filters we tested only caught between 50% &#8211; 75% of the spam (even the ones  that claimed to catch 99% or more).  SpamHero consistently catches over 98.5% of  the bad stuff.  The details on how we accomplish this is worthy of it&#8217;s own blog  entry so I&#8217;ll have to get back to that soon.</p>
<p><strong>Mistake #2: Throw away a lot of your good mail as  &#8220;spam&#8221;.</strong></p>
<p>Even companies that claim to specialize in this area  seem to fail miserably&#8211;ouch.  It&#8217;s probably because they take the same  out-dated approach to filtering.  We do things differently.</p>
<p>This topic also deserves it&#8217;s own entry so instead of getting into the  technical side of it I&#8217;ll just ask: Have you ever seen someone win the lottery?   Probably not.  And you&#8217;re even less likely to see SpamHero trash a good  message.  While scanning over a half billion messages per day, our filtering  engine averages less than 10 false positives.  That&#8217;s less than 1 in 10  million.  Not bad.  For the average email user that&#8217;s less than 1 good message  being lost in 100 years.</p>
<p><strong>Mistake #3: Makes you look like a spammer to the rest of the  world.<br />
</strong><br />
To keep things simple most spam filters will accept email  that is sent to any address at your domain.  Unfortunately, spammers like to  impersonate domains that have this feature enabled.  As a result, millions of  people around the world could be receiving spam that has your domain listed as  the sender&#8217;s email address.  That certainly can&#8217;t be good for your  image.</p>
<p>Of course, we love the idea of keeping things simple.  So we  designed a smarter solution that gives you the best of both worlds.  By default  we leave the email &#8216;catch-all&#8217; feature turned on for the first 30 days (you can  force it to stay on if you prefer).  During that time our system automatically  learns what email addresses are valid for your domain.  The catch-all feature is  automatically shut off after 30 days and we only accept mail for your valid  email addresses from then on.</p>
<p><strong>Mistake #4: Make your domain a bigger target for  spammers.</strong></p>
<p><strong></strong>Recently a customer that was moving to SpamHero from  another filtering service forwarded a message from the other company.  They were  trying to win back their customer by pointing out that their domain had received  over 600,000 spam messages so far that month.</p>
<p>Since we were already  filtering mail for this new customer I decided to investigate.  It turned out  that in less than 24 hours spammers had sent mail to over 1,000 unique email  addresses on this customer&#8217;s domain (the customer had less than a dozen &#8220;valid&#8221;  remail addresses).</p>
<p>This is something spammers like to do to domains that  have the &#8216;catch-all&#8217; feature turned on.  Fortunately, our service automatically  detects the valid email addresses and shuts off this dangerous feature.  So I  calculated that this customer would cut down their inbound email volume from  over 600,000 messages per month to around 5,000 messages per month&#8211;just by  switching to our service.</p>
<p>On a side note, these kinds of practices can  falsely inflate a spam filter&#8217;s accuracy<br />
rating.  I won&#8217;t go into the logic  of how this works but I&#8217;ll offer a hint: it has to do with spammers sending 99%  of the spam to invalid addresses on your domain.</p>
<p><strong>Mistake #5: &#8220;Tuning, tweaking and training, oh  my!&#8221;<br />
</strong><br />
Unless you&#8217;re an IT expert then the idea of tuning your  spam filter probably sounds daunting (and with good reason).  Some services ask  you to train their filter so they know what &#8220;your&#8221; spam looks like.  That&#8217;s  rubbish.</p>
<p>We wouldn&#8217;t stand for such non-sense.  SpamHero goes undercover  to spy on what the spammers are up to.  Our distributed network of spam traps  instantly detects and adapts to the latest spam storms.  No tuning, training or  tweaking required.</p>
<p><strong>Mistake #6: Charge setup fees and per email box  fees.</strong></p>
<p><strong></strong>With the level of automation that exists today there is  really no excuse for a &#8220;setup fee&#8221;.  Oh yeah, and if you have more than a few  email addresses on your domain they want you to pay extra for that too.</p>
<p>That&#8217;s all old-school thinking.  We&#8217;d rather focus on giving our customer as  much value for their dollar as possible.</p>
<p><strong>Mistake #7: Charge an extra fee to view the spam that&#8217;s been  filtered.</strong></p>
<p><strong></strong>Yes, most companies charge an extra fee for the  &#8220;message quarantine&#8221; feature.   Perhaps they&#8217;re concerned that if you could see  what they&#8217;ve marked as &#8220;spam&#8221; you might notice how much of your good mail  they&#8217;re actually throwing away.</p>
<p>We&#8217;ve got nothing to hide.  People will generally see <a href="http://en.wikipedia.org/wiki/Halley%27s_Comet" target="_blank">Halley&#8217;s Comet</a> more often than a good message being  caught in their SpamHero quarantine.</p>
<p><strong>Mistake #8: Require you to call or fill out a form to get a  price.<br />
</strong><br />
This one doesn&#8217;t affect long-term service but it always  makes me wonder what  they trying to hide.  It&#8217;s amazing to me how many  companies still take this old-fashioned approach.</p>
<p>People don&#8217;t like being  left in the dark.  So we&#8217;ve tried to make SpamHero as transparent as possible.   It just makes more sense.</p>
<p><strong>Mistake #9: Signup today, they&#8217;ll get back to you some time&#8230;  next week?</strong></p>
<p><strong></strong>A lot of spam filtering services take several days to  get setup from the day you fill out their order form.  Is that due to poor  design or lazyness?  Not sure but we feel that&#8217;s totally unacceptable.</p>
<p>We had 3 design goals when we created our order &amp; setup process:<br />
1) Must be simple to get started (intuitive order process, etc)<br />
2) Services  must activate immediately upon ordering<br />
2) Entire process should take 5  minutes or less</p>
<p><strong>Mistake #10: Innovation not included.</strong></p>
<p>Before we began creating our service we did a lot of research.  One thing we  noticed among many of the older spam filtering companies is that their website  (or control panel) looked like it was created in the 90&#8217;s (and never updated  since).  And this is something we&#8217;ve encountered in most industries.  It seems  that once a company reaches a certain point they get comfortable and stop  innovating.</p>
<p>We&#8217;ve got a huge list of features we plan to implement.  Check back often and watch us as we show what we&#8217;re made of.  <img src='http://www.spamhero.com/blog/wp-includes/images/smilies/icon_smile.gif' alt=':-)' class='wp-smiley' /> </p>
