Why CyberMail?

Built From Scratch, Not Bolted On

We didn't wrap someone else's mail server — we wrote our own in C for maximum performance and control

Purpose-built C email server — not a wrapper around Postfix or a third-party service. Full control over every connection, every packet.

🌎

Global Server Network

Multiple nodes across North America and Europe. DNS round-robin load balancing with automatic inter-node relay failover if any node goes down.

Frequently Asked Questions

Everything you need to know about our email delivery service

What makes your infrastructure different?
Unlike most email delivery services that wrap existing open-source mail servers, we built our own email server from the ground up in C. This gives us full control over performance, security, and deliverability. We run dedicated nodes across North America and Europe with automatic inter-node failover, built-in anti-spam intelligence, and HMAC-authenticated node synchronization.
How easy is it to integrate?
Very easy. If you can send emails from your current setup, you can use our service. Simply update your SMTP settings (host, port, credentials) or use our REST API with just a few lines of code. Most customers are up and running in under 5 minutes.
What happens if I exceed my plan limits?
You'll receive a notification when you're approaching your limit. We won't cut off your service unexpectedly — you can upgrade your plan anytime, or contact us to discuss options. No surprise charges ever.
How does the free tier work?
The free tier includes 9,000 emails per month (300/day), forever. No credit card required to sign up. You get full access to our SMTP and API endpoints, real-time analytics, and email support. Perfect for testing, development, or small projects.
What kind of emails can I send?
You can send any transactional emails: account notifications, order confirmations, password resets, system alerts, reports, and more. We also support marketing emails on paid plans, with proper opt-in and unsubscribe handling.
Do you support custom domains?
Yes! All plans include custom domain support. You can send emails from your own domain (like [email protected]) with full DKIM, SPF, and DMARC authentication. We provide simple DNS instructions to get you verified in minutes.
What about email deliverability?
Deliverability is our top priority. Every email is automatically signed with DKIM, and we configure SPF and DMARC for your domains. Our built-in anti-spam engine screens outbound messages against DNSBL blocklists and scans for malicious URLs — keeping our IP reputation clean so your emails land in inboxes, not spam folders. Higher-tier plans include dedicated IP addresses for maximum deliverability control.
What kind of analytics do you provide?
You get real-time tracking for all your emails: delivery status, bounces, complaints, and more. View detailed logs, filter by date range, and export data. Plus webhook notifications to integrate delivery events with your own systems.
