Welcome Email – From 'WordPress'

Hi Sonia,
Yes, that’s correct.

If you’re using v1.3 (the latest version of the plugin at time of writing), the ‘New User – Welcome Email’ doesn’t allow you to change the from name or email address due to a restriction in WordPress.

Please see this screenshot of what this notification looks like including all options: https://www.dropbox.com/s/z381mmswmde1dz9/Screenshot%202015-07-13%2015.12.09.png?dl=0

Hope this helps.

Thanks,
Jack
