How to sned e-mail and SMS to hundreds of users in exchange 2003 and 2007?

Exchange 2003, SMS

Hello, Actually our exchange platform is Windows 2003 for one domain and exchange 2007 for the other domain. There are 35000 mailboxes between the two domains, So, I have the following requirement

We are building a process for which users and staff can sign up for SMS and/or SMTP notification of corporate messages of varying importance.
Our requirement is this:

Given a list of SMS numbers and SMTP email addresses, we need to send a message to both lists as fast as possible without being flagged as spam
by the providers

Is it easier to establish this internally on one or more servers, or to have an external solution?
Either way we need a complete solution that will handle the above requirement.

Could you give me a hand with this?
What am I supossed to be?

We actually have installed on one PC mail atomic sender to send e-mail to hundreds of people but I would like to know if there is another way to do that and also to deliver SMS Messages

Regards,

A hosted solution will probably be easier for the actual sending of the SMS messages.

I found this http://smseverywhere.com/developers.htm which is an API which you can use to send SMS messages in bulk from our own application.

As for the sending of email, if it's all internal emails I would setup Distribution lists, and build a web based self service site which users can use to add or remove them selves from the distribution lists.

If you need to be able to send to outside users as well I'd recommend a system such as Lyris (I've used it which is why I recommend it). We used it to send a couple of million messages per day.
