Email addresses should better handle lowercase, with mixcases

[PicoCreator]

When requesting for emails using mixed (with upper) case. We would need to also fetch lowercase emails, as some email sending providers will normalize to lowercase.

Example send to "[email protected]"
And depending on the email provider, it sometimes goes to "[email protected]"

Additionally when "pasting" the address into the "address bar" - it should automatically filter out the "@Domain" part
