if you are receiving more than 1 result per iteration, there is something wrong with your filter.
You should receive only 1 result per field requested when filtering using ID == your_variable
The idea is that you receive a set of information
and then use the build string action to build for example a table of all the elements you queried.
You can set up a table using html markup in build string:
Store the result in "THE_MULTI_LINE_VARIABLE"
After the foreach, place another build string
<table> <tr><th>ID</th><th>Title</th><th>OTHER</th></tr> THE_MULTI_LINE_VARIABLE </table>
store again in THE_MULTI_LINE_VARIABLE
When you now send a mail containing the variable, you should receive a table
