I would like to send HTML newsletter emails to about 5,000 - 10,000 email addresses collected through an opt-in newsletter signup on my website.
I know how to use BCC in ASP.NET 2.0 to send emails. But I want to minimise the impact of our SMTP mail server. The email addresses are stored in SQL SERVER 2005.
So this is a tough question, it's about the performance issue. And I know how to send email, what I want to know is how to improve the performance and minimise the impact of SMTP server.
