Complete B2B outreach infrastructure · MCP · API · Web UI
Every email is individually inbox-verified.
Run relevant B2B outreach through MCP, API, or a full web UI. Every message is checked with its exact creative and sending context. Inbox — billed. Spam or not delivered — stopped and not billed.
LDM does not optimize for send volume. It controls the quality of each contact and charges only when that individual message is confirmed in Inbox.

How LDM works
One recipient. One message. One placement decision.
Inbox Placement is a required step in the flow of every individual email — not a periodic campaign metric.
02
Prepare a relevant message
Generate the creative for that person, their company and the reason to contact them now.
03
Run an individual Inbox Placement check
LDM tests the exact creative with the actual sending conditions, then branches automatically.
Inbox → send, count, billThe verified message continues through the outreach flow.
Spam / fail → stopDiagnose and change the creative, relay or other sending conditions. No charge.
Two equal interfaces
One platform. Two ways to operate.
Agents and humans work with the same contacts, campaigns, placement decisions, replies and pipeline data.
MCP / API for AI agents
Connect LDM to an agent or your own automation without losing operational control.
- Find and create contacts
- Score ICP fit and prepare creative
- Launch and control campaigns
- Process replies, CRM records and pipelines
Full web UI for humans
Operate the complete platform directly, supervise agent actions, or step in manually at any point.
- The same contacts and context
- The same campaigns and placement results
- Visibility into agent actions
- Manual operation whenever needed

Experience behind LDM
LDM was shaped through real B2B outreach projects across software, manufacturing, professional services and international markets.
Real projects across software, manufacturing, security and professional services.
Core capabilities
From targeting to reply — in one controlled outreach loop.
LDM connects recipient selection, context-aware creative, verified delivery and reply handling in one operating system.
Targeting and context
Find relevant companies and people, score ICP fit, and prepare a concrete message for the recipient and their current context.
Inbox-verified delivery
Manage sending accounts and conditions, check each message individually, and stop automatically when placement fails.
Replies, CRM and feedback loop
Capture and classify replies, continue the conversation in CRM, and feed outcomes back into targeting and creative.
Who LDM is for
For teams that would rather send 100 relevant, inbox-verified messages than 10,000 blind emails.
LDM is built for deliberate B2B outreach where the quality and economics of each contact matter more than raw send volume.
- B2B teams, outbound specialists and small agencies
- Developers of AI SDRs and autonomous sales agents
- Companies with irregular campaigns that do not justify large fixed plans
- Teams that want to pay for a verified action instead of access to a sender
Usage-based pricing
Pay per individually inbox-verified message.
Most platforms charge for access or sending volume. LDM charges only for an individually verified Inbox result — with no large monthly infrastructure subscription or seat-based access fee.
Inbox is billed. Spam or not delivered is stopped and not billed.

FAQ
Technical answers, without the sales fog.
Is every email tested individually?
Yes. Every message goes through its own required Inbox Placement check with that message's exact creative and sending context.
What happens when a message lands in Spam?
LDM stops the flow for that message and does not bill the result. You can diagnose and change the creative, relay or other sending conditions before running a new check.
What exactly am I paying for?
You pay for one individual message that receives a confirmed Inbox result in LDM. Access, send volume and a failed placement are not the billing unit.
Do I pay for messages that fail Inbox Placement?
No. Spam and not-delivered outcomes are not billed. Only an individually verified Inbox outcome is charged.
Does Inbox Placement guarantee a reply?
No. LDM confirms delivery to Inbox, not a reply or sale. A response still depends on recipient relevance, the offer, context and the message itself.
Is LDM only an MCP product?
No. MCP and API are full interfaces for agents and automation, alongside a complete web UI for people.
Can I operate LDM through the web UI?
Yes. The web UI works with the same contacts, campaigns, placement results, replies and CRM data as MCP and API.
Is this a monthly subscription?
No large monthly access subscription is required. Pricing is usage-based per individually inbox-verified message, billed post-paid monthly.
Can the LDM team operate the platform for me?
Yes. A managed rollout is available, but it uses the same LDM platform and is not the primary product plan.
What is the difference between the managed pool and BYO sending accounts?
The managed pool uses sending infrastructure operated by LDM. BYO uses sending accounts that you connect and control. Both follow the same individual placement and billing rules.
Can LDM run on-premise?
Yes. LDM can be deployed inside your infrastructure with its full web UI, MCP and API. Your contacts, CRM data, credentials and AI configuration remain under your control. Inbox Placement can connect to LDM’s verification infrastructure as a metered external service.
Do I receive the LDM source code?
No. On-premise customers receive a licensed deployment package and Docker images. Open SDKs, MCP clients and integration examples are available separately, but the core LDM platform and Inbox Placement infrastructure remain proprietary.
Who maintains an on-premise installation?
The customer can operate and update the installation independently using the provided deployment documentation, or purchase managed deployment and support from the LDM team.
Want us to run it for you?
Our team can launch and operate the same LDM platform for your project. You keep visibility into targeting, messages, Inbox Placement, replies and results — and can move to the web UI or an AI agent later.
Start managed. Move to self-service when ready.
