The contact tag is the prefix for several contact:* keys to describe contacts.
For the most common keys, the shorter version outside the 'contact' scheme is used more frequently, over the time until now: phone=*, fax=*, email=* and website=*, with other contact tags used rarely outside the namespace scheme. Both schemes are in use for a long time and exist in parallel. Many applications are able to use both of them.
To limit tag fragmentation, consider using the most used keys.
At the same time a proposal to deprecate contact:phone=* was not successful - Discussions/tagging/contact:phone or phone. Idea of deprecating either tags without contact: prefix or ones with contact prefix is repeatedly suggested, often triggering huge discussion and ending with conclusion that there is no consensus. Please, read past discussion before starting a new one.
You should only add contact information to POIs and not to any private address!
Email-addresses which are only available on a website after solving a captcha, or which are in other ways obfuscated to protect against SPAM-bots should not be tagged in OSM. The same applies to fax and phone numbers.
