I used Email Integration successfully on a 3.x site when migrating people from an old fashoined mail list. It served it's purpose well, but a year or so down the track we have now turned it off because it does have it's drawbacks. These include server load and the inability to moderate posts by email. Also, having a new post automatically go out to all subscribers almost immediately after the post can be a real problem if the post is innappropriate or spam. There's also a bit of an admin overhead because people don't understand how it works and are incapable of following instructions

I don't use vB 4, I'm still on 3.6, but I have just found another solution. I installed this https://vborg.vbsupport.ru/showthrea...ighlight=sorky which adds an RSS feed to each forum and sub forum, (this may already exist in vB 4.x)

My site has a primary level forum (which doesn't actually act as a forum), then about 8 sub forums. So I republish the RSS feed for the primary/parent forum as an email "newsletter" through feedblitz.com and give our forum members the link to the Feedblitz sign up page for the email newsletter. You can tell Feedblitz to check for new posts in the RSS feed daily, 8 hourly, 4 hourly or "express" which is the most frequent. Every time there is a new post in one or more of the sub forums the subscribers get an email.

With the users' permission you can import them as subscribers into your Feedblitz account.

There is unfortunately a cost for using Feedblitz depending upon the number of susbcribers. A free alternative (the on free one I know if) is Feedburner.com (owned by Google) however that only provides a daily email to subscribers.

I hope this helps.
