Bulk Email

[RFH Reseller: creativeworks]

I've previoulsy extended a past post, but still would like a technical answer!

We are compiling an email within a Stored Procedure and firing it out through our dedicated server using CDOSYS.

Potentially, the subscribers could reach the tens of thousands, and our server only has 10 SMTP connections available - it took 3 hours to send a test batch of 10000 emails. Not only does this block up email sending on our server, it takes too long!

Using CDOSYS, we are able to point to any SMTP server. Is our best option buying hosting for a dedicated SMTP server, or is there another solution we can consider.

I appreciate your comments...

Why do you only have 10 SMTP connections?

At work, we have a dedicated server with a hosting company that's apparently don. (hint hint).

I don't pretend to understand the fundamentals of email sending, so don't know which questions I should be asking or searching - we create emails through our websites, and these get sent to the IIS queue, which inturn then goes to a Mailenable queue to be sent... (?)

Our hosting company said we only had 5 available connections, they opened this up to 10?

But this didn't help with bulk email sending... it took upto three hours to send 10000 emails.

OK, so it's not RFH you're using. I expect they are worried about getting blacklisted.
And why would 3 hours be a problem anyway?

because of the brand this is for, i don't think the subscribers are going to stop at 10,000... could be 10 times that... by which time, we creating more emails before the first lot have been sent out!

You might be better using a bulk sender if its important such as www.constantcontact.com.

If sending 10,000 e-mails in 3 hours 'blocks up' e-mail sending, maybe you should be spreading out the sending of them over say 24 hours, in small batches that give the server enough breathing space to run usual mail services with minimal disruption?
I am assuming that the 3 hours is too long comment is due to it being 3 hours of being unable to reliably send other email.

spot on! we can't afford to block other regular mail coming off the server.

Do 500 per hour like Nick said, that might help.

10,000 is just a number i chose to test on... The actual amount of subscribers will be more over time.

This is a daily email for those who choose to subscribe to it - ideally it would be good to start something late at night, and have it finished by the morning... somewhere between 6 and 9 hours to play with I guess.

How many SMTP connections can I convincingly ask the host to open?
