Email OTP Verification in Android Studio

Question

I am student and working on my university final year project . It requires to sign up with a verification of email.

I have tried Java Mail for send email with OTP code. I have used google and outlook emails but both of them blocked/warned me for sending spam mails, as All the mails have been sent from my email and it looks like spam.

I want to if there is any free/cheap system for sending and verifying email to be used with android studio . As I can't go with making new email again and again.
