Enterprise Email Infrastructure at Scale
For senders approaching a billion emails per month who want to own their IPs and reputation. We don't sell software — we sell the time of the world's best email engineers, embedded in your Slack, working alongside your deliverability team.
Built by Email Infrastructure Pioneers
Laneful is founded by the team that built and ran SendGrid, the largest ESP in the world. We don't just provide software. We develop it, deploy it, and operate it for you, even on your own infrastructure.

Engineer-Led Operations
We don't sell software or infrastructure. We sell the time of the world's best email engineers. They operate our MTA on your behalf, adapt it to your exact needs, and embed directly in your Slack — available like a member of your own team.
Whether you need custom MTA queue controls, a new routing policy, or fully private infrastructure in your own cloud, our engineers make it happen. You focus on strategy. We handle the stack.
Features
Email Lanes
Use dedicated IP lanes with full tracking, bounce handling, and compliance. Group lanes into tracks for smart routing across marketing, transactional, and other traffic types.
Deliverability Engine
AI agents continuously monitor your traffic to detect spam risks, bounce spikes, and engagement drops, offering instant, actionable insights to keep your emails landing in inboxes.
Latency Awareness
Laneful distinguishes between urgent (transactional) and flexible (broadcast) emails. The system routes each type through the right lanes to avoid delays and ISP throttling.
AI-Powered Warmup
Forget static warmup schedules. Laneful auto-adjusts IP warming based on real-time bounce and engagement signals, ensuring smooth, scalable delivery without manual effort.
Security & Trust
Laneful is built with security at its core, protecting access, data, and reputation across every layer of your email infrastructure.
Phishing-Proof Logins
Replace passwords with passkeys, which provide secure, device-based authentication using Face ID or fingerprint. No reuse. No phishing risk.
Granular API Key Control
Lock each API key to specific IPs or CIDR blocks. Unlike global account-level rules, Laneful enforces per-key restrictions for precise, secure access.
HTTPS Everything
All links, including tracking, unsubscribe, and redirects, use HTTPS on your custom domain. SSL is automatic, with zero setup required.
Built-in DMARC Monitoring
Get simplified, real-time insights from complex DMARC reports. The agent helps you configure, enforce, and evolve your policies without third-party tools.
Security is not an add-on. It is baked into every lane.
Your AI Co-pilot for Deliverability
Laneful's AI agent works behind the scenes, surfacing insights when needed and responding to your questions when asked.
Proactive Issue Detection
Instantly identifies and explains deliverability threats, such as bounce spikes and low engagement, before they impact your sender reputation.
Smart Recommendations
Get clear, data-driven advice on configuration changes, warmup pacing, and when to expand your capacity for optimal performance.
Guided DMARC Adoption
Simplify DMARC with step-by-step guidance. The agent helps you move to full enforcement confidently, protecting your domain from spoofing.
Real-Time Feedback Loop
Ask questions via the dashboard or API and get immediate, context-aware answers based on your live email traffic.
