lemlist, run as part of the engine
lemlist is an outbound platform for multichannel sequences: email steps, LinkedIn touches and wait conditions chained into campaigns, with sending controls and deliverability tooling around them. In the lead-to-care cycle it owns outbound execution inside acquisition and signals. This is where a list becomes conversations.
We know the tool from the inside. We have operated lemlist at scale in production, and that experience shapes everything below: the failure modes are not theoretical to us, they are things we have caught and fixed on live campaigns. Deliverability, list hygiene and reply handling are operational subjects here, not checkboxes on a setup guide.
What Buildrhaus builds with lemlist
- Lead pushes behind a dedup gate. Before a contact enters a campaign, an automation checks whether they are already in another sequence, already a customer or already talking to someone on your team.
- Replies on the right records. Every reply and interest signal lands in Attio on the right person and company, tagged with the campaign and step that produced it.
- Campaign setup through the API. Repeatable launches, sender rotation and sending schedules handled by automations instead of error-prone manual setup.
- Production monitoring. Stuck sequences, bounce spikes and sender issues surface in a channel you actually read, before they burn a domain.
How it connects
Campaigns, leads and activity are all reachable through the API, which makes full automation practical rather than partial.
Sends, opens, replies and unsubscribes fire webhooks that we route through n8n into Attio as structured signals.
The same event stream feeds reporting in the CRM: replies per campaign per segment, readable next to your pipeline, so a campaign is judged on conversations created rather than on open rates.
Free Ceiling Scan
If replies live in lemlist and deals live somewhere else, your team is flying half blind. The Ceiling Scan is a free diagnostic of your revenue engine, outbound included. You get a clear map of what leaks and a quoted next step, nothing else.
