When I type "mom" into the "To:" field, Mail.app doesn't load my mom's email addy:
…but when I click the blue "circle/plus" button and type "mom" it does:
In Contacts.app I have my Mom's contact info set up so that her "title" is "Mom".
How do I get Mail.app's To: field to auto complete based on her Contacts.app title? Or, is there something I can do in Mail.app so that "mom" will autocomplete her email addy from the To: field?

Title is intended to be used within the scope of a company. If you want Mail to recognize names such as “Mom,” try using the Nickname field instead:
On the macOS version of Contacts, you can go into Contacts → Preferences → Template → Add Field and check Nickname. That field will then become available by default when editing any contact, without requiring you to add it through the + menu.
