Sponsors won't email me back?

I've offered the sponsors, and I'm awaiting reply, and it says "Negotiations ongoing" with the little green bubble next to it but I haven't had any responses yet?

Ok weird all my emails just came through now at the same time (4 minutes ago)

There is a time delay when in negotiations (as in real life) - it doesn't happen right away.
The shortlist page should tell you the time remaining.

Yes for sponsors it is 2 minutes. Mine took almost an hour.

You used google when you sent the emails...
