What the mod does is throttle the email sending rate to 80% of your server limit (which you input manually as a new key on the email configuration page). So if you set a value of 1000 for the server limit, it will send emails at the rate of one every 4.5 seconds, giving an overall rate of 800/hr. That leaves a reasonable percentage of the server allowance for normal store emails to proceed unimpeded.

The script progress is shown on the admin page, and it shouldn't tie up a lot of server CPU resources (on linux servers) because the mod uses the php sleep function as the throttle. I don't think it's suitable for Windows servers though - I believe the php sleep function doesn't work the same on those.

This is the MOD link I received from Neville (bunyip) back in 2009. It works really well for me and does exactly what is needed i.e. throttles

A number of people I know have tried it and it has worked for them without any problems. You can download it from .custom cartmods.com/clients/down loads/throttled_newsletter.zip - but obviously use at your own risk.

I hope Neville doesn't mind I post it here, it just seems such a waste that such a great MOD is available but not many people know of it. I've tried contacting him again, but haven't received a reply thus far.

I decided to add to this as I found a good work-around. I recently signed up with send grid .com and they have different maximums based on how many e-mails you send. I have the basic $10/month account that allows you to send 40,000 e-mail's per month. I've had much better delivery rate success as well as their servers are more reliable than a standard php e-mail script. Takes about 5 minutes to integrate into zencart. I've probably sent 10,000+ e-mails through them and they are great.
