Any reason why the send email node won't work in this situation?

toemailrecipient only accepts 3 Appian types as input: email address, user and group.

To use toemailrecipient on a text, you have to first wrap it with toemailaddress(). See the attachment.

Or as others mentioned just use toemailaddress() and no need to wrap it with anything, it will just work too.
