We don't just promise inbox delivery — we guarantee it contractually. Our deliverability engine ensures every email lands where it belongs.

Guaranteed by SLA — contractual
In our entire operating history
Maintained 24/7 by our team
Every email lands in the inbox — not promotions, not spam. Guaranteed by our deliverability SLA.
We actively manage your sender reputation, IP health, and domain scores 24/7.
Every email is scored before sending. High-risk content is flagged and blocked automatically.
Failed deliveries are automatically retried with exponential backoff — nothing gets lost.
Real-time dashboards showing delivery rates, opens, clicks, bounces, and complaints.
Hard and soft bounces are automatically managed to keep your list clean and your score high.
Sub-100ms average delivery. 100% uptime SLA. Balanced load across multiple sending nodes — so your emails never queue, never delay, never fail.
Contractual guarantee. If we miss it, you get service credits automatically — no questions asked.
Emails are distributed across multiple sending nodes automatically. No single point of failure — ever.
If a sending node goes down, traffic instantly shifts to healthy nodes. Zero impact on delivery.
200+ edge nodes ensure your emails are routed via the fastest path to any recipient worldwide.
No email queues. Every API call triggers immediate sending — no waiting, no batching delays.
Your transactional email content is never stored, never read, and never accessible to anyone — including our own team. Enterprise-grade security on every API call.
Your email content — subject lines, body, attachments, recipient data — is processed in memory and immediately discarded after delivery. Nothing is stored. Nothing is logged. Nothing is readable by anyone.
This is enforced at the infrastructure level, not just policy. Even if someone wanted to read your transactional emails, the architecture makes it technically impossible.
All API calls and SMTP connections use TLS 1.3 — the strongest encryption standard available.
Secure API key management with per-key permissions, rate limits, and instant revocation.
Every outgoing email is DKIM-signed with your domain key — proving authenticity to every recipient.
All attachments scanned for malware before sending — protecting your recipients and your reputation.
Outbound content is checked against spam patterns to protect your sender score automatically.
Email content is never stored. Only delivery metadata is kept for your analytics dashboard.
