Thanks, this will always be a concern for these types of services. I will be keeping this service running indefinitely as I use it myself everyday along with friends and family. I originally created the service to solve my own problem.

The best way to mitigate against the risk of a service shutting down is to use your own domain name. That way, by simply changing your MX records to another email provider, you can continue to receive emails as normal.
