Hi Author,
I wrote a trigger to avoid duplicate contacts, but the problem with it is that it throws an error when I try to update(any other random field) an existing contact record because it compares the email with the same record’s old version and throws an error. I thought your code might solve the issue but it is the same in your case too.
The above trigger is not suitable for ‘before update’ , I am working on the solution for the same, will post soon.
