Questions? Answered.
What counts as a domain?
Each unique sending domain your customers use. If one customer sends from acme.com and mail.acme.com, that's 2 domains.
What happens when I hit my email limit?
You pay overage rates — $0.90/1K on Starter, $0.75/1K on Growth, $0.50/1K on Scale. No surprise bills, you can set alerts.
Can I upgrade or downgrade anytime?
Upgrade instantly — we prorate the difference. Downgrade at the end of your billing cycle.
What's the difference between shared and dedicated IPs?
Shared pool means your tenants share IP reputation with other Ark customers (we manage this carefully). Dedicated on Scale means each customer gets isolated IP reputation.
Do you offer annual billing?
Yes. Save 17% on any plan when you pay annually.
