Connect PDL and Lemlist in Deepline, describe the ICP, and Claude runs search + likelihood gate + Lemlist import.
People Data Labs to Lemlist is a supported Deepline workflow path for Claude Code. Use it when an agent needs to run People Data Labs, inspect the returned fields, and write the reviewed result into Lemlist with run history, retries, and explicit failure states.
Best query match
“How do I connect People Data Labs to Lemlist with Claude Code?”
Source primitive
People Data Labs returns structured fields that Deepline records with provider attribution and row-level status.
Destination primitive
Lemlist receives only reviewed rows after the pilot command succeeds.
This workflow moves data from People Data Labs into Lemlist with Claude Code as the orchestration layer. It is strongest when you need a repeatable, inspectable handoff with explicit auth, cost math, and recovery steps.
First callable command
curl -s "https://code.deepline.com/api/v2/cli/install" | bash
deepline auth registerOne command installs the Deepline CLI and registers a workspace. Takes about 30 seconds. You only do this once per machine.
curl -s "https://code.deepline.com/api/v2/cli/install" | bash
deepline auth registerIn the Deepline dashboard, click Integrations → People Data Labs → paste your API key. Deepline uses PDL inside waterfalls and also directly via its dedicated search/enrich tools.
In the Deepline dashboard, click Integrations → Lemlist → paste your API key from Lemlist Settings → Integrations. Deepline pulls your campaign list for one-click destination selection.
Open Claude Code and describe the workflow in plain English. Deepline handles the tool calls, waterfall routing, rate limits, auth refresh, and dedup. An example prompt for this pair:
> From PDL, find Heads of Product at US SaaS companies with 51-500 employees. Likelihood >= 8. Push to Lemlist campaign "Product Leaders" with pdl_id, job_title, and job_company_size as custom variables for the sequence copy.Once Claude's one-off run looks right, type "Deploy this as a workflow" and tell it the schedule. Deepline wraps the exact prompt + tool chain as a recurring workflow with run history, billing, and alerting in the dashboard.
> Deploy this as a workflow that runs every weekday morning at 8am.For 1,000 leads: $2.80
~0.28 credits per PDL match. Lemlist import is free. Deepline's credit pricing is pay-as-you-go — see code.deepline.com/docs/pricing for current rates.
Deepline tries the cheapest provider first and only falls back if it misses. For People Data Labs workflows, this means email enrichment stops at the first valid hit — you don't pay for the second and third provider unless you need to.
Once the one-off run looks right, "Deploy this as a workflow" wraps the same prompt + tool chain as a cron-scheduled workflow. Run history, per-run billing, and retry logic all live in the dashboard. No DevOps.
People Data Labs keys, Lemlist OAuth, waterfall fallbacks (Hunter, Dropcontact, Findymail, Prospeo) — all live in the Deepline dashboard. Rotate once; every workflow picks up the new credential automatically.
“Instantly gives me the highest reply rate by far — higher than any other sequencer I've tried with the same Apollo list.”
“A proper email waterfall lifts match rate to 80%+ versus 35-50% from any single provider.”

Cause: People Data Labs credentials are either expired, revoked at the provider side, or the account tier doesn't expose API access.
Fix: Click the integration row in the dashboard → Test Connection. If it fails, re-paste the API key (or re-run OAuth for key-based providers). Confirm the provider account tier includes API access — most providers gate this to paid tiers.
Cause: The filter returned 0 matches, OR rows failed a downstream gate (email not verified, already in destination, deliverability check failed).
Fix: Open the run in the Deepline dashboard → expand the step-by-step trace. Every row's path is logged: matched/unmatched at each stage. Most frequent culprit is the email-verification gate. Loosen the filter or remove the gate in the prompt if that's the cause.
Cause: Either hit a provider rate-limit, ran out of Deepline credits, or the destination API returned 500s Deepline classified as permanent.
Fix: Dashboard → Workflows → Recent Runs. Failed runs show the exact error and a "Replay" button. Credits are visible top-right. Rate-limit issues auto-resume once the window resets; permanent errors need intervention.
No. You need Claude Code (the CLI/IDE). Deepline provides the tool-execution layer and credit system. Your Claude Code subscription or Anthropic API key handles the LLM calls — Deepline handles the GTM actions underneath.
Built-in. For Lemlist as a destination, Deepline uses the provider-native idempotency key (email for HubSpot/Attio, External_Id for Salesforce, campaign-level dedup for Instantly/Smartlead/Lemlist). Reruns update existing records instead of creating duplicates.
Yes. Paste them in the Deepline dashboard under Integrations. Deepline uses your keys for the actual provider calls — you keep your provider contracts, billing, and rate limit allocation. Deepline's credit billing only covers the orchestration + waterfall layer.
Deepline runs exactly what you describe. The 1000 in cost-math is the reference cost per 1K rows — a 3-row run costs 3/1000 of that total. You never pay for rows that don't exist.
Yes. Mention it in the prompt — e.g. "If People Data Labs doesn't return an email, fall back to Hunter → Dropcontact → Findymail." Deepline assembles the waterfall automatically and charges you only for the provider that successfully finds each row.
Connect People Data Labs and Instantly in Deepline, describe your ICP as an Elasticsearch-DSL query, and Claude runs search + enrich + filter-by-likelihood + Instantly push. Skip-on-low-confidence by default.
Connect People Data Labs and Smartlead in Deepline, describe the ICP as an ES-DSL query, and Claude runs search + likelihood-gated enrich + Smartlead import.
Connect Apollo and Lemlist in Deepline, describe the filter, and Claude pulls + verifies + imports. Lemlist's multi-channel sequences (email + LinkedIn) pair naturally with Apollo's firmographic filters.
