IPhone email memory?

I got an email Sunday saying that my memory was full and have just noticed that I haven't received any emails since that. I'm pretty sure I d have received some since then but they aren t showing even though I've bought new memory. Any idea why?

I highly doubt you can add more memory on an iPhone, try deleting some useless stuff like game apps

IPhones can use a number of email providers for the service. The storage for those emails is through them, not the iPhone itself.
