I work with a team of people from all over the world. We have about 10 websites, for various demographics, however all deliver pretty much the same service.
For the site which I manage myself, I am trying to learn about email marketing. I have a couple of questions and will really appreciate any help.
1) When a customer buys a product, is it legal to save their email address even when having no intentions in selling it on to anyone else?
2) How does it work when a visitor is reading a blog, and after a minute or so of reading a little popup message appears on screen offering them something for free if they join the mailing list?
I understand these are very newbie questions, especially the second one but my technical skills in this area lack.
Thanks for your time,
