How come I can't email my photos from my camera roll on iphone? It does allow me to send via text

I might actually, for once, have an answer here. All of the above helped me work through EXACTLY the same problem the OP had - it asked me to set up a new Google account, then told me that it was already there. . .

I do NOT use Mail - EVER - and had turned it off in my settings at some point over the past few months. I suspect there may be others like me who use the gMail app rather than Mail.

So just by chance I happened to be in Settings/ Mail, Contacts etc/ Gmail and noticed Mail was turned off. I turned it back on and went back to the photo I was trying to email and it sent first time without having to even turn the phone off and on again.

😀

I REALLY hope this helps someone - I have never been able to offer an answer before.
