Plugin for sending optional letter on a directory website
I run a directory website which is quite promising. A way forward, subscribers will need to opt-in for a newsletter which is suitable for their need based on age, gender etc. So in this case, what might suit Mr. A, might not suit Mr. B. I actually need a plugin (or how do I go round it) to enable subscribers on the blog subscribe to the newsletters that suit their lifestyle. Your advice will be highly appreciated
