Subject: No Subject

[FlatbushPush718]

Whenever I send an MMS, the person who receives my text gets a line that says "no subject" first then my message starts on the next line. I think the "no subject" line is very unnecessary and I would like to remove it from my MMS. Is there a way I can get my MMS to stop saying "no subject" when being sent? The "no subject" line doesn't appear on my phone it only appears on the persons phone who im sending the MMS too. I attached a photo of what I mean.
