Support & Pricing
KumoMTA
Free unlimited access to KumoMTA, all features, and the Kumo Community

Because KumoMTA is Open Source, we don’t charge for the software — this work is sustained entirely through sponsorships. When you become a sponsor you not only gain access to support and services, you also help power the continued innovation and progress of today’s most advanced email solution.
All prices are for sponsors sending up to one billion messages per year, with no limits on number of servers.
Higher volume senders can contact us for custom pricing.
