Pay once. Keep the tier forever.
We sell the system, not the send volume. Your SMTP handles delivery, so nothing is metered. Tiers scale on workspaces, seats and stored contacts. Buy another code any time and it stacks onto your account.
All prices in USD, charged once. Checkout is handled securely by Stripe and codes are delivered to your account immediately after payment. No email limits on any tier.
