Email field - save submited emails

You can do it manually by single SQL query and something like acesql Joomla extension.

SELECT DISTINCT field_value FROM jos_js_res_record_values WHERE field_type = 'email' AND section_id = 1

So submitted emails (via email field) are acctually stored in DB? When I run query I just get entered email in field_value. What about values from additional field schema or description or page URL? Can I see those?

If this is not possible with email field, can I somehow create another Type an Section that will be responsible for inquries made from website. And I would like to include this Type in my main type as contact form. Is there a way in this case to get the URL from where form was submited (like email field).

Depending what you need. If only one field you may use API method renderField. And for URL use

JRoute::_(Url::(record($row->record_id)))
