What happens if I hit my monthly quota?
Sending pauses until the next calendar month or an upgrade — we never silently drop mail or surprise-bill you for overage.
Do I need a credit card for the free plan?
No. Sign up, verify a domain, and send. The free plan is a real plan, not a trial.
Can I send marketing and transactional mail from one account?
Yes — broadcasts, automations, and transactional sends live in one console, with per-domain and per-topic controls, and suppression checks on every path.
Is annual billing available?
Yes, Pro is available monthly or annually. Manage it from the console's billing page, powered by Stripe.
