I want an easy and versatile component free of charge to set up during my website. I search a great deal and located some components like cc e-newsletter, letter guy etc...

However i can't to able download.

Can there be any component that is open to send e-newsletter for that activated customers. Kindly assist me of the problem.

Thanks ahead of time.

I am unsure that which you mean about the inability to download. You will find a number of e-newsletter components available, I have used AcyMailer and it is very good.
