How to add a newsletter to a VB forum? Suggestions Please!

[محروم.كوم]

I'd like to start sending a weekly newsletter to my forum members and would like to find a service or modification that can help with this.


I'd like the service or mod to have the following features;

• Some form of tracking / stats
• An ability for members to opt out of receiving the newsletter
• Ability for members to opt in, but preferably would not require double opt in
• Something that makes it easy to add the existing forum members to the service
• Ability to easily integrate the service with the forum registration page.

Any suggestions or recommendations would be welcome.

Thanks! __DEFINE_LIKE_SHARE__
