EMAIL INFRASTRUCTURE FOR HIGH-VOLUME SENDERS
Hands-on email engineers. One fixed monthly price.
We write the MTA, run it in our cloud or yours, and work on deliverability with your team directly in Slack.
Founded by Isaac Saldana, co-founder of SendGrid. SOC 2 Type II.
01 · SUPPORT
Get help from the engineers running your email.
When a major send slows down or messages start bouncing, you need people who can diagnose the problem and act on it. Laneful engineers work directly with your team in Slack, with access to the sending system and the experience to investigate what is happening.
No ticket queue and no account manager between you and the engineer.
Work with a team that knows your setup
Our engineers learn your traffic, routing and sending requirements. They work alongside your team through onboarding and ongoing operation, so support is grounded in how your email actually works.
Get people who can make changes
Work directly with the engineers who can investigate queue behavior, review provider responses, and adjust routing and throughput. They help your team turn an identified issue into a plan for resolving it.
Prepare for the sends that matter
Bring us your launch schedule and peak sending requirements. We help plan capacity, warmup and routing before the send, and work with your team when delivery needs attention.
01 · SUPPORT · MIGRATION
Protect delivery while you make the switch.
Switching providers means protecting the delivery performance your business already depends on. Our engineers plan the transition around your traffic, IPs and provider contracts, then work with you through warmup and cutover.
- STEP 01Map the setupReview domains, IPs, traffic patterns, suppression handling and renewal dates with our engineers.
- STEP 02Keep your current path availableWhere appropriate, we relay mail through your existing provider while new IPs warm on Laneful.
- STEP 03Move traffic in stagesAdjust the pace using delivery signals and the needs of each traffic stream.
- STEP 04Complete the transitionAgree on the conditions for cutover, along with a fallback plan, before retiring the old setup.
02 · FIXED COST
A bigger sending month should not mean a bigger bill.
When your email bill tracks your message count, growth and busy sending periods push costs up. Laneful gives you a fixed monthly cost for the capacity you agree on, so a launch or a seasonal peak doesn’t change the bill.
When you outgrow that capacity, you move to the next tier. Each step costs less per email than the one before, so the savings grow as you scale.
03 · DELIVERABILITY
Protect the reputation you build.
Your sender reputation takes time to build and is easy to damage. Laneful sends your mail on dedicated IPs, separates your traffic the way your business needs, and puts engineers, backed by our AI tools, on the signals that show when something is going wrong.
Decide how your traffic is separated
Dedicated IP pools and routing rules separate transactional and marketing mail, or organize sending by customer. Time-sensitive messages get their own path.
Catch issues before they spread
Our AI tools watch bounces, deferrals, complaints and engagement, and our engineers bring what they find to your team.
See which domains and IPs need attention
Review Gmail Postmaster, Microsoft SNDS, DMARC, bounces and complaints in one view, with the evidence behind each flagged domain or IP.
Adjust warmup as conditions change
Warmup pacing adapts to delivery signals, with engineers helping your team manage the rollout.
Test inbox placement before a send
Send a test message to live test mailboxes and review where it lands before sending to your audience.
Pass insights to your customers
Platforms can pull deliverability issues through our APIs and surface them directly to their own customers.
FOR HIGH-VOLUME SENDERS
Own your IP range and keep it
If your volume justifies a full IP range of your own, we help you acquire one registered to your company and route it for you. The range, and the reputation built on it, stays yours if you ever move.
PLATFORM
Find delivery problems and know what to change
Use the dashboard and API to see how your sending is performing. Your engineers and ours can inspect the same delivery activity, investigate problems and decide what needs attention.
04 · SOFTWARE & MTA
We wrote the MTA. We run it where you need it.
Self-hosting an MTA gives you control, but your team still has to run it and own deliverability. Laneful gives you the same control with an MTA built for speed and scale, operated alongside you by the engineers who wrote it.
| Layer | Self-hosted MTA | Laneful |

Need something the MTA doesn’t do yet? Queue controls, routing policies and new features are built for you by the people who wrote it.
Laneful cloud
We host and operate everything. The fastest way to start.
Your cloud
Laneful runs inside your own cloud account, operated by our engineers.
Your datacenter
Run on your own hardware when your data has to stay on premises.
Hybrid
Split traffic between our cloud and yours as your needs change.
Connect to your existing systems
Send through the API or SMTP. Use webhooks, an OpenAPI specification and SDKs in eight languages to connect Laneful to your application and workflows.
05 · OPERATIONAL EXCELLENCE
Run by engineers who scaled SendGrid.
Email at that scale takes world-class distributed-systems engineering and operations. We deploy, scale and stay on call for your sending, so speed, scalability and fault tolerance are our job, not your team’s.
Speed
Queues, routing and concurrency tuned by the engineers who wrote them.
Scalability
Capacity planned around your busiest hour, before the send, not after it.
Fault tolerance
Deployment, scaling and on-call handled by people who have kept email flowing at massive scale.
PROOF
Test the volume your business depends on
Run a throughput benchmark against receiving infrastructure you control. We size the test to your real traffic, the busiest hour you send today or expect to, and your team measures the results with its own tools.
Plan a throughput test- Share your traffic profileYour peak hour, message sizes and the providers you send to today.
- We send to a server you controlUnique messages at your target rate, against your own receiving setup.
- You measure the resultsThroughput, latency and errors, with your tools and your numbers.
