MX18 is an email delivery platform built on an enterprise-grade MTA and API stack. You integrate via SMTP or API, and MX18 handles routing, deliverability optimization, compliance, analytics, and real-time feedback loops to ensure your emails reach inboxes reliably.

Billing is based on the monthly email volume you choose. Each plan includes a defined credit limit, and usage resets every billing cycle. You can upgrade anytime if your volume increases.

You can start with the free plan, which includes a monthly email quota, sandbox access, and full API/SMTP testing. This lets you validate integration, deliverability, and dashboards before committing to a paid plan.

We support major credit/debit cards, UPI, net banking, and internationally accepted cards. For enterprise clients, we also offer invoice-based billing.

Yes. MX18 offers a free plan with a monthly allotment of emails and access to all core features so you can test sending, analytics, and deliverability before upgrading.

For high-volume or specialized needs, you can reach us through the “Get Started” button on the pricing page or email hello@mx18.com. Our team will help tailor a plan to your technical and business requirements.

If you exceed your plan limits, sending continues seamlessly and additional emails are billed as overage at the applicable per-email rate. You can also choose to upgrade your plan proactively.

We count every email submission received through API or SMTP - regardless of final delivery outcome. All attempts are logged in your dashboard with real-time usage tracking so you always know how much of your quota is used.
