Feedback on email campaign

Hello! I'd like to get feedback on this email campaign that was sent on March 27, 2025. We have low click rates on our emails and can't seem to get registrations from our classes. Email marketing isn't the only thing we're doing, but years past, email marketing used to be a bigger method of getting registrations. Also, our users open their emails on desktop versus mobile. 

This is the email that was sent: https://conta.cc/4l4zFhW

Thank you so much!

Sincerely,

Kate
