Before and after

What changed

Before

You have a sharp brief in your head. By the time you open Lemlist on a laptop, walk through five forms, write four sequence steps, set up sending schedules, and copy paste enriched contacts in, the day is gone. You stop briefing as often as you should.

After

You DM your Slack bot: "Series A HR tech in the US who hired a CRO in the last 30 days, 2 step LinkedIn plus 3 step email." A minute later, a preview lands in the thread. You tap a thumbs up. The campaign sits in DRAFT in Lemlist, ready for you to start when you want.

How it works

The breakdown, gate by gate

DM the Yalc bot

One natural language message in a Slack DM or app mention. ICP, channel mix, step count, all in plain English.

Slack Socket Mode

LLM parses the brief

The agent extracts the structured ICP, the channel mix, and the step count from your sentence. If something is missing, it asks one focused question in the thread.

LLM

Sourcing plus enrichment

Your existing Lemlist campaign chain takes over. Fiber for sourcing, FullEnrich for verified contacts, deduped against your pipeline before any copy gets written.

Fiber MCPFullEnrich

Per persona copywriting

Each tier of contact gets a different sequence. VP gets the strategic angle. Manager gets the team productivity angle. IC gets the daily friction angle.

Block Kit preview in thread

A full preview of the campaign renders as a Block Kit message in the same Slack thread. ICP summary, sequence steps, contact count, send schedule.

Thumbs up ships DRAFT

Only the original sender can approve. Thumbs up reaction or a `yalc approve` reply ships the campaign as a Lemlist DRAFT. Never live without your tap.

Results

What goes in, what comes out

Natural language in. DRAFT Lemlist campaign out. Approval gate guards the send. From four Slack messages, you have a paused campaign ready to ship.
