Features
You Own Your IPs: Never Migrate the Hard Way Again
Your IP ranges and sender reputation belong to you, not your provider. Laneful helps you acquire the IP blocks and routes them on your behalf, so the reputation you build is portable. Switch providers, or leave us entirely, and your warmed-up IPs come with you: no re-warming, no deliverability cliff, no lock-in.
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.
Simple, flat-rate pricing
One flat monthly fee per lane. A lane is one dedicated IP, and you pay the same whether you push a million or a billion messages through it. No per-message fees. No shared IPs. Companies typically pay 2-40X less than with per-message ESPs, with deliverability automation and embedded engineers included.
Flat fee per lane
You pay a flat monthly fee per lane, not per message. Each lane is one IP with up to 20 concurrent ISP connections, and your lanes are operated by expert engineers in your Slack.
Volume-independent
Send a million messages or a billion through a lane, and the bill is the same. Scale freely without watching a per-message meter tick up.
2-40X cheaper, better features
Companies typically pay 2-40X less than with per-message ESPs, with dedicated IPs, AI-powered warmup, and engineers embedded in your team.
The minimum engagement is 256 lanes (one class C block). You own your IPs, and Laneful helps you acquire the ranges, then routes and operates them on your behalf.
