I own a big board on vB4 with 5.4M posts and 300k members. We have partnerships with sponsors who advertise banners on our site. Some of them also send out a weekly promotional newsletter. Initially we used our own email to send these newsletters, but had obvious issues with spam control. Then we looked at Mailchimp and similar services, but for 300k members it's prohibitive.
So we came across a little "mass pm" mod for vB4 that works just fine.
Every member can opt out from this by simply unchecking an option in their control panel, this option being just a custom profile field that we created.
So at the same time, the mass pm mod takes this custom profile field into account, letting users opt-out, and we send newsletter for free, without having to rely on 3rd party email applications/sites and keeping our email database under control.
Has anyone been able to deploy something similar? I was unable to find anything close to this, there's the "MassAlert" mod, but it seems to me that alerts are supposed to be "quick and short" and I didn't see the option to use a custom profile field.
Still on the same subject, I found two choices of banner management add-ons in XF, one which is free yet very limited, and another one which is EUR 60 but seems very complete. The "rotating banner system" in vB does pretty much the same for free. So I'm also looking for an alternative here, maybe something in between?
Thanks in advance.
