I'm posting a piece of before insert/ update trigger, it has to populate custom email field on Opportunity into Account's Email custom field.
I'm trying to do something like this:
For(Opportunity opp : trigger.new)
{
If(!SetEmaiIDs.contains(opp.Email__c)) // checking if added email is already not present on some other account
{
opp.Account.Account_Email__c = opp.Email__c; // This line is throwing error
}
Seems like this line 'opp.Account.Account_Email__c' is not working
Can't we access account field like above , it is giving
Attempt to de-reference a null object: error on same line
Thanks !

Trigger.new or Trigger.old contains only Object information, not any relationship fields.
You could make the trigger to 'after insert, after update'
Then use
Btw, using before insert you can't update parent object fields with out using DML statements
So, you need to modify the program and update parent Accounts using DML
