This is only true depending on how seasoned a netizen someone is. True story: I have a friend of mine whom I once verbally communicated a (now long-gone) gmail address to, with Swedish pronounciation. The result was him smirking a bit, and some time later asking me if I got the pictures he sent to my "gaymail.com address". This could just as well have ended up being "geemail.com" or "yeemail.com" had I gone with English pronounciation. He just didn't know what google or gmail was. He doesn't use the net in the same ways we do.

But let's be realistic... it's not like the world of internet users suffered from a supposed problem with miscommunicated email addresses before "geemail.com" came around. We managed just fine.
