Is it correct to only use the element <address> for an email?
For example:
<address><a href="mailto:[email protected]">[email protected]</a></address>
Examples that I always see are something like street address, city, etc.
Would you have any rules telling me where I can or can not add this <address> element, or can I put it wherever I want? obg:)
It's not wrong to just put an email because this element is meant to insert contact information about your page when used globally within the <body> element or on an author in cases where it is being used within the element <article> .
It can be used to report from a simple contact email as in your case, as well as to inform a complete address of a physical location. Here are some examples below.
Simple example:
<footer>
<address>
<p><a href="http://www.w3.org/Consortium/contact-mit">MIT</a></p>
</address>
</footer>
Example with address:
<footer>
<address>
<h5>Contate-nos</h5>
<p>
Rua Leonardo Mathias, 100, Sala 30<br>
Vila Roitman - Santos/SP, 11244-444 </p>
<p>
<abbr title="Phone">Tel:</abbr> (11) 5555-4577
</p>
</address>
</footer>
Example with article:
<article>
<header>
<h1>The Very First Rule of Life</h1>
<p><time pubdate datetime="2009-10-09T14:28-08:00"></time></p>
</header>
<p>Lorem ipsum dolor sit amet, consectetur adipisicing elit. Numquam autem similique totam molestias dolorum, eius iusto cupiditate ex debitis fuga. Quaerat minima harum esse iste voluptates quod, magnam placeat sapiente.</p>
<footer>
<address>

Usually this element is used within the <footer> element, but you can use it in other elements as well, as long as it is being used for contact information, so you will not be wrong.
