That would be interesting software to build in. What is this newsletter software you use, is it open source? (If so, please send a link).

Thanks very much indeed... it's great to find that people like the software and it will be very nice indeed to have a drink on you this weekend to celebrate! ;)

All the best...

Yes, it's been almost 10 years of hard work and it's going well. The newsletter program is phplist. Free and open source! They call it domain throttling. It slows transmission of the emails per domain so you don't get flagged as spam. I'm using an older version. I believe it's gotten better over the last few years. The newsletter feature on zen is on my list to investigate. If it isn't robust, I'll load a fresh phplist to the new store. Unfortunately, I'm not good enough with code to fully integrate it. I had promised to teach myself but have never gotten further than mucking around with it and occasionally getting lucky.
If you can slow the transmission of the messages, that would be great! For stock notifications, it wouldn't have to be by domain; just general. Something simple like 1 every 8 seconds would be fine. By the way, combining the list into one email per customer is really nice. Currently they get 1 per item and I think that's triggering some spam filters, too.

Cheers!
