dreamhost就不说了，是很多国内“穷人”租用的老美提供的服务器空间服务。

最近邮箱里连续收到dreamhost ps(Private Servers)促销的邮件，手法值得学习。

第一封邮件：

邮件标题：You’re invited to DreamHost PS(看上去不错，让用户觉得自己是被邀请的，似乎得到了尊敬)

再看邮件主要内容：

* You get your own PROTECTED system resources for improved stability.
* You get more flexibility than regular hosting to run any process.
* You can scale your resources on the fly, and reboot your own PS.
* It’s currently only +$10/month for every 100MB of memory.
* It’s a completely seamless transition from our regular shared hosting.

oh~原来是要我花10美刀一个月去租100M内存的Private Servers服务，一年120美金，和我现在用的dreamhost服务价钱($119)没啥区别，但是似乎没能说服我换成这个服务。

第一封邮件置之不理。

二天后，第二封邮件来了。

邮件标题：Perhaps you’d like DreamHost PS if we gave you 33% off?(kao，我给你33%的价格下调，你接受不？)

邮件主要内容：

We can understand if you’re perhaps not interested at this time.. it’s
true the minimum extra monthly charge is $15 (for 150MB of resources).

But… what if we gave you $5 a month off… forever? What THEN?

Well, what if is what NOW… if you sign up in the next week (by 2009-04-13),
you’ll automatically get a 150MB DreamHost PS server for just $10/month…
forever! That’s 33% off (give or take .3333333333333333333333333…%)!

The main advantages of DreamHost PS are:

* You get your own PROTECTED system resources for improved stability.
* You get more flexibility than regular hosting to run any process.
* You can scale your resources on the fly, and reboot your own PS.
* It’s currently only +$10/month for every 100MB of memory. ($5 off!)
* It’s a completely seamless transition from our regular shared hosting.

开头就说我们知道你可能对这个服务没啥兴趣，因此我们出血本让利给你，你还不要么？

可惜的是遇到我了，继续置之不理。

再过2天，第三封邮件来了。

邮件标题：Our final offer.. DreamHost PS for 66% off!(咱受了多大的委屈，最后一口价，下调66%，买了吧？)

主要内容：

Well, it’s hard for us to understand how you couldn’t give it a shot for
just $10/month (33% off). But not impossible for us to believe. What’s
IMPOSSIBLE for us to believe is if you don’t take advantage of this, our
final and greatest offer!

$10/month off.. forever. That’s 100MB free.. meaning you can get your
very own Private Server with 150MB of ram for just FIVE dollars a month!
Awooooooga!

The main advantages of DreamHost PS are:

* You get your own PROTECTED system resources for improved stability.
* You get more flexibility than regular hosting to run any process.
* You can scale your resources on the fly, and reboot your own PS.
* It’s currently only +$10/month for every 100MB of memory. ($10 off!)
* It’s a completely seamless transition from our regular shared hosting.

开头的这一段的确能吸引很多人，只是我继续无动于衷。

三封邮件到此结束，为什么这么便宜我还是不买？

不是我没有这个需求，能有PS服务总归比虚拟主机好，只是，我一直有一个疑问：这个PS服务是根据所使用的内存来收费的，基本上是10M/月/美金，超出就要收费，试问：DH你凭什么来判定我的使用超出了？你的这个凭据可信度有多高？如果你“乱收费”，那我怎么办？

如果DH不解释清楚这个问题，我想我还是不会使用这个服务的，哪怕比我现在用的要便宜的多得多。
