The payload is sometimes split into parts that are encoded. Do something 
like this:

from email.header import decode_header

def decode_payload(header, default_encoding='utf-8'):
     parts = []

     for data, encoding in decode_header(header):
         if isinstance(data, str):
             parts.append(data)
         else:
             parts.append(data.decode(encoding or default_encoding))

     return ' '.join(parts)
