Can I use Netflix vouchers multiple times?

Hi, I recently bought a Netflix voucher so I can have a trial month. Sounds stupid, but you always have to enter an account or a code so that you can pay the contract after it expires. My question now would be if you do a trial month, cancel the contract immediately and then conclude a new contract with a different email address, where you then enter the code of the same voucher?

Nowhere else can you use vouchers twice.

Once activated, the code is invalid for the next time!

It doesn't matter which email address you enter!

A code prevents multiple use of vouchers.

A code is gone when you have used it, and if a new code with this combination is in circulation again, it has to be activated again.

Otherwise, the code rules out multiple use…
