First, we have our own ideas on privacy. Then, welcome contact depends on a lot of variable factors. For example, we all like free stuff. Furthermore, a recommendation from a friend could be considered fair game. It follows, a personal preference. So, address sharing signups are not cool for email. Given, proper netiquette to refrain from sharing others personal info. As a result, don’t give out other contacts emails.
Next, email addresses are personal contact information. And so, direct access to our inbox. It follows, emails of friends should not be shared with others. Then, information would becomes public.
In any event, privacy is lost when personal info is given away without permission. However, does not stop marketers from trying. Also, many websites have successfully added users from friends of friends emails.
For our sake, ask permission before sharing personal information. Please, keep the information personal. On the other hand, we can share a link in social media.
Hence, we maintain a certain level of trust with associates email. We do not give out their private stuff. Then, they do not give out ours in return. A reciprocal relationship.
