Bill Haack SOQL Junction Query
I have a Junction object name AcctContactAff which I use to create a many-to-many relationship between Contacts and Accounts and stores (among other things) the title of the person at the account.
Being new to SOQL I am really struggling to get the following to work:
SELECT Id, Name, NPI__c,
When I run this I get the error message: "Didn't understand relationship 'AcctContactAff__r' in FROM part of query call."
However, I can get the query to work when I do this:
SELECT Contact__r.id, Contact__r.Name, Title__c, Name
FROM AcctContactAff__c
I absolutely need to run the query from the Parent object not the Child object.
Can anyone tell me what is wrong with the first query statement?

this is the complete code:
I do not want to bring all the contacts associated with the account for sending email, I want it to be sent only to the contact associated with the contact to the invoice.

List<Contact> listofContacts = [SELECT Email FROM Contact where AccountId = :accId and Email != null];
String[] toRecipients = new List<String> ();
Integer count = 0;
for (Contact oneContact : listofContacts)

toRecipients.add(oneContact.Email);
count++;
