The EN email note is somewhat kludgy. It was better before the last major upgrade. Before the last upgrade it was seamless to other EN notes. I suspect but don't know what broke.
BTW - they kept around the EN classic app because so many things broke. For a while I was going back and forth between the two.
The EN competitors want you to convert email to a PDF. One of the competitors said they would have to have an email server to convert email to a note. They said this is hard.
I am OK that it is hard for everyone except Apple. Apple does already have an email server. Why are they forcing me to convert the email to a PDF?
