I am writting a .asp/.aspx program to send newsletter to (n) subscribers,
one at a time ( don't want to use BCC or CC fields )
I was wondering if there are 2000 subscribers or more will asp page be able
execute for such a long time ?

So how programs are written to send newsletters , is it simple .asp/.aspx
programs or some other stuff also. Pls Guide with your comments and URLs.

Regards
Jigs

Hi Jigs,

I've found that writing a simple script which reads from a column in a
database table and then loops through a collection of e-mail addresses in a
database table, using CDO's MailMessage class.

You're on the right track...it might be easier to write a script which sends
one copy of each message to each recipient in the mailing list...instead of
BCC'ing or CC'ing each one. You can then personalize your mailings this
way. Different SMTP servers on the distant end may not accept e-mail
messages with too many recipients in a field. This way, your own SMTP
server shoulders the majority of the work, and then sends your message out
cleanly to your distribution list.

Here's some code to help you do this...assuming you have a DB with an
"Email" column.

' do DB connection stuff prior to this code, and instantiate a DataReader
object, named objDataReader
Dim objMailMessage as MailMessage
objMailMessage = New MailMessage
objMailMessage.From = "Click here to reveal e-mail address"
objMailMessage.Subject = "Hello world!"
objMailMessage.Priority = MailPriority.Low
objMailMessage.Bcc = "Click here to reveal e-mail address"
objMailMessage.Body = "This is my body...it is a temple!"
objMailMessage.BodyFormat = MailFormat.HTML
Do While objDataReader.Read()
objMailMessage.To = objDataReader("Email")
SmtpMail.SmtpServer = "localhost" ' This is a new mandate for
.NET V1
SmtpMail.Send( objMailMessage )
Loop

However, just note that I've personally only used this to send out e-mail to
a few hundred recipients at the same time...I haven't scaled it for a
mailing list of 30,000 recipients.

You can e-mail me outside of this thread at Click here to reveal e-mail address if you'd like the
full sample as an .ASPX page, and I'll send the VB.NET source code to you.

Have fun!

Jason

I just finished writing a ListServer application in ASP.NET and it seems to
handle large mailings very smoothly. It is processing messages to 1600
recipients (individually sent) with attachments in about a minute and a
half. The only issue I had in building it was something in the underlying
CDO was mangling certain attachments so I'm using a third party component
called AspEmail which I've been very happy with. As far as writing the
script, you would take your standard mail script enclose it in a recordset
query loop that supplies the email addresses and any personalized content to
build the message.
