Hi there, rosilee.
I see that you'd like to subscribe to Apple Music using a Student subscription. The issue is, your school's email address isn't recognized. I'm happy to help.
Get an Apple Music Student subscription -- UNiDAYS validates that you and the school you're attending meet the requirements. The first footnote in the second section quoted below may also provide a clue.
If you're a student at a degree-granting university or college1, you can join Apple Music for a discounted membership price2 for up to 48 months (4 years). The time does not need to be continuous.
The Apple Music Student subscription is only available in certain countries and regions. Learn more about Apple Music availability.

Apple Music features might vary by country or region.
About validation
When you join Apple Music as a student, UNiDAYS, a student validation service, confirms that you're enrolled in a degree-granting university or college1.
Periodically, UNiDAYS re-validates your student status. If UNiDAYS finds that you're no longer a student or if you have a Student subscription for a full 48 months, your subscription automatically becomes an Apple Music Individual subscription.
