Q: sending notes

I have a new iPhone SE and have encountered a problem that I had on my older phone but don't remember how it was resolved. I often use the Notes app to send messages to myself via email. I'm more likely to see them if they show up in my mailbox than by sharing them with Notes on other devices via iCloud. I've realized that notes sent from the new phone don't show up in my mailbox. They do if sent from an iPod Touch, so the problem seems to be communication between the phone and other devices. Is there a setting I can change?
