I don't have an iPhone or any other gadget which sends emails. All my emails are done via laptop or desktop. So I don't understand the other end experience on this.
Is it difficult to add a Subject line on gadgets?
If I knew what was involved I could rebuke and advise more effectively.
I do find this laziness a growing nuisance. It's difficult to handle a lot of email threads with blank Subject lines - I rely on it to triage priority to open and read/ action;
and looking up the email address to see who this contact is, is a real pain waste of my time.
