When to use it
The at sign. Writing email addresses with @ does not hide them from scrapers, because any HTML parser decodes the entity before reading the address.
The name comes from the HTML5 list (much of it shared with MathML), so it works in every current browser but not in XML or XHTML served as XML, where the numeric reference is the safe choice.
