What does that mean? Several people asked already if an entry in SOST transaction appeared after you ran the Z... program and you are just saying "OK". Was or was not an entry created? It's a simple question. If "ok" means that an entry was created then there is no issue whatsoever.
There is additional program that needs to run to actually send out the emails (and many things can fail on the way - e.g. an email could be cought by the spam filter).
As others noted, it's very unlikely that a change in the subject line could break anything. You're obviously missing something and either not understanding what SOST transaction is and how emails work in SAP or failing to communicate to us.
