Dear Experts,

I want to develop bulk emailing application for my clients using asp.net 3.5.

I am using valid credentials for sending mails and trying to send 250 emails per hour but still server blocked my domain account.

What is the best way to send bulk emails without spamming.

Thanks and Regards

Sign up with Constant Contact or one of the other bulk email services.  They have their own servers and spend 24/7 making sure their emails get thru.  Almost all ISPs and web hosts refuse to allow bulk email because they don't want their IPs to be blacklisted which could affect all of their clients, not just you.
Biggest question is are you the admin of the Mail Exchanger server you are sending from?  You need to throttle the amount of mail that is leaving your mail server.  If you are performing a directed mailing list, as in to a single email server, their spam software is set to block you after so many messages.  

"Ours is set to 25 an hour"

So couple things:
- have them white list you
- slow your outbound messages down
- send from multiple domains

Other than that the spam filters will block you.

>>  sending mails and trying to send 250 emails per hour  . .

I know that Discountasp.net has a limit of 1000 per day.

I once tried to send some email and didnt' know about this, and the
shut the website down, . . a busy ecommerce store.
I had to email like mad to get them to get it back online.

You're gonna to have to use one of these services but they are very
expensive. Let me know if you find one that has a good deal
because I couldn't.

They have their own servers and programmers.  They aren't limited by an ISP, they are big enough to afford their own backbone internet connections.  And they are very careful about following the 'rules' so they don't get themselves blacklisted.  It's the same with the bulk email services.

The Best solution is to use one of the bulk email services like Constant Contact.  The only other solution I know of is to become your own ISP.
