Gathering a list of email addresses is one of the things any new website should do. This should always be done legitimately – buying in email addresses is inefficient and in some countries illegal. if you get someone to sign up to your newsletter (or whatever) of their own free will, then your email list will be much more valuable to you.
Unlike other forms of digital marketing, email marketing creates a willing (they signed up) and focussed (when they open your email, you aren’t competing for attention) audience. This is what makes it so powerful. Also, the relatively low bar to entry in terms of both skill and money make it a vital form of digital marketing for basically any business.
