Edge MTAs in Mumbai, Singapore, Frankfurt, Virginia.
Engineers in chat — not a tier-1 script, not a chatbot.
Built on three pillars
Most email platforms outsource one of the three things that actually matter — authentication, the MTA, or the reputation pipeline. We own all three. That's how we deliver consistently.
SPF, DKIM, DMARC, BIMI signed and verified on every message. Auto-generated 2048-bit keys, quarterly rotation, one-click DNS setup.
Built in-house by our engineering team in Node.js. Single-binary, sub-100MB per worker, handles 10K TPS per node comfortably. Scales horizontally on its own — SaaS, VPC, or fully on-premise.
Automatic IP warm-up. Per-ISP throttling. Live feedback-loop ingestion. Suppression hygiene that never forgets a complaint.
Under the hood
Every region runs an independent intake → queue → MTA → tracking pipeline. No single point of failure. No noisy neighbours. Sending IPs are warmed and managed continuously, so your reputation only goes up.
Developer-first
One JSON response. One msg_id. One source of truth for every recipient, every event, forever.
Short-lived JWTs for the dashboard, long-lived mdsk_ keys for production — scoped to send-only or read-only.
Author once, send with substitutions. Auto-detect placeholders, GUI editor, full version history.
Every send returns a msg_id. Fetch the full timeline of any message, anytime.
// One API. Any volume. Any region. const res = await fetch('https://api.maildoot.net/v1/messages', { method: 'POST', headers: { 'Authorization': 'Bearer mdsk_********', 'Content-Type': 'application/json' }, body: JSON.stringify({ from: 'alerts@yourapp.in', to: 'ananya@gmail.com', subject: 'Your OTP is 482931', html: '<p>Valid for 5 minutes.</p>', tags: ['otp', 'auth'] }) }) // → 202 Accepted // { msg_id: "msg_a3f8...", status: "queued" }
What sets us apart
