Yes! It works now. Thanks. Got me stuck there for a while.

Also I think I have been able to filter the emails now. My implementation is thus:- I wrote a regex (for the unsubscribe word) and added an `else if` block...

Great! I've opened a PR. I used `Str.regexp_case_fold` as opposed to just `Str.regexp` so I believe that makes it case agnostic.

The link to version 8.3.8 (the latest version as of this writing) examples is broken as well. Here: https://redux-form.com/8.3.8/examples/
