Vouchers are promotional codes Vayvio issues (for example, beta access codes):
- Enter the code where prompted (sign-up or Billing).
- If valid and unused, the voucher applies — typically free access to a plan for a period, or a discount.
Rules that keep them fair: one redemption per voucher per user, usage caps per code, and expiry dates. Vouchers grant access — they're not cash and can't be exchanged.
