Sends email notifications even when disabled

I have all notifications disabled, yet I keep getting these.

```
You follow @linuxaddicted on twitter, and now you both have public keys on Keybase, with signed twitter connections. This is cryptographic utopia! You should consider tracking them, which commences a signed record of their public key and identity announcements.
```

Please make it stop.


Start by reviewing the issue description and screenshot, then reproduce the email notification while all notifications are disabled. Done means the shown notification is no longer sent when notifications are disabled; no source file or test is named in the report.
