In which Office 365 Plans is Planner available?

According to Support, Planner is not available for non-profit E1, only for the regular/commercial E1.

EDIT: Here's the email reply I got from support after talking with them on the phone. I find it incredibly frustrating that none of their written material (including this email) explicitly states that non-profit E1 is excluded from Planner. I wonder if it's because non-profit E1 is technically E2.

Thank you for taking my call today. As I have discussed, MS Planner will only be available for the following plans:  Office 365 Enterprise E1, Office 365 Enterprise E3, Office 365 Enterprise E4, Office 365 Enterprise E5, Office 365 Education, Office 365 Education E3, Office 365 Education E4, Office 365 Business Essentials and Office 365 Business Premium. When generally available, Planner will be included in several additional Office 365 plans. Stay tuned for more details.
