The main challenge for these kinds of services is that they're only as useful as they are unknown.

If they start getting popular, they either

- start getting slammed with volumes of spam that are so high that the creator needs to start paying some serious hosting fees to keep the service running

- get blacklisted

Mailinator has outlasted all its competitors because it addressed both problems very early on. I wish receiveee best luck but I'm betting that it won't be around in a year from now.
