Thanks for giving that a shot. In testing with my own address, I got the results I expected. Luckily I'm not seeing any technical issues, per se. Connections to the data providers are working fine, and they are returning results.
I see you've run against 10 rows thus far. I'd encourage you to run against more rows, to ensure you get a larger sample to draw conclusions from.
Common reasons for no results would be the people's privacy settings, which may prevent providers from accessing details. Other people might have accounts under a different email address, and so on.
That said, keep in mind that enriching personal emails tends to yield less information than work emails. (In part because data providers don't always expose personal emails.)
