Are you getting complete subject in actual email when you receives it into your inbox ? If not , you may need to change the length of subject field on email template or email notification table. Alternatively you   could set subject using mail script.

I suspect many email programs can't handle subjects longer than 255. And some sources advise that you should respect RFC2822, where messages SHOULD be no more than 78 characters.

Well, its a bit more complicated and depends on the Email Client.

The 78 Characters may be excceded if the Subject is split into multiple lines:

Bottom line: it makes sense that the subjects gets no longer than the default 160 characters.
