one email per property or individual email accounts

[Frank Leon]

I have a colleague that owns multiple properties and is trying to be a more efficient with tenant communications. She currently mainly texts, but wants to transition to email. In setting up her email, she's curious which would be the better way:

1. Create one email account per property (prop1 at gmail dot com, prop2 at gmail dot com, etc)

2. Use one email for all properties (management at gmail dot com)

3. Buy a domain name, to look more professional, and create one email alias per property (prop1 at management dot com, prop2 at management dot com, etc.)

Thoughts?  and thank you!
