Thanks for the informative thread about mass mail guidelines.. Definitely something we all should be familiar with.

As far as dealing with large mailing lists... We have over 135k members in one of our forums and it definitely is a nightmare to email them.. Here are some of the work-arounds I have used.. Keep in mind a lot matters on what server(s) you have and what they can handle..

When I do mass-mailing I will almost always do it very late at night or early in the morning.. You can also shut down your forums to reduce loads..

Limit who you are emailing by selecting (example) only those members who have been active in say, the last year.. There are a lot of variables you can chose to minimize things.. My primary forum has been around for over 6 years now and there is no need to email people who haven't been active or visited in the last 4 years, etc..

Purchase and use a dedicated mail server.. I've you have a really large and active site, you probably are going to be sending out a lot of email due to subscription notifications, etc.. Having a dedicated server will ensure that the loads won't hurt your forum activity..

Use a third party mass-mail service.. You can export your email list out of vBulletin and do this.. Be careful who you use though.. I'm sure there are some out there that would love to get their hands on your email list..

Just a few thoughts..
