Sorry if I hurt you
Sorry if you didn't get the email
Sorry if it didn't arrive on time
If, if, if.
Usually, there's no "if" about this situation, so why does it get tossed in? Do we really suck that badly at apologizing? Or is it plain poor writing (if instead of that) to blame for the problem? Stop it with the ifs already. Suck it up, admit something went wrong and just apologize for it. Sheesh.
