Argorant + lemlist
lemlist campaigns start with a list that lands.
Argorant builds the audience - filtered by industry, role, size and country, verified at export - and lemlist runs the sequence. Clean data in, replies out.
565.8M contacts · valid-only direct push · no automatic sending
Setup
Connect lemlist to Argorant
The direct Argorant-to-lemlist path connects through a revocable API key, lists the campaigns available to that key, and adds valid contacts from one completed export to the campaign you choose. It never activates the campaign or starts sending.
1
Connect a lemlist API key under Profile → Integrations and confirm the intended campaigns are visible.
2
Build the segment, inspect the count, and complete a valid-only Argorant export.
3
Choose the exact lemlist campaign and push the export; standard identity, company, title, and location fields are mapped automatically.
4
Review pushed, skipped, and failed totals in Argorant, inspect the campaign in lemlist, and activate sending only when you are ready.
Deliverability
Protect the domains that do your selling.
lemlist warms your inboxes; a single bad import can undo it. Verification at export keeps hard bounces out of your sequences, which keeps your domains sending and your reply rates honest.

The campaign picker uses the connected lemlist workspace. Argorant deduplicates repeated emails and destination-scoped retries, maps the fields your variables need, and reports what lemlist accepted, skipped, or rejected.

The complete, testable workflow
Published by Argorant
lemlist is a current direct Argorant sequencer provider. Connect a lemlist API key, choose an existing campaign, and push a completed export. Argorant strictly selects valid rows, maps lead fields, deduplicates retries and repeated emails, and reports pushed, skipped, and failed totals. The connector only adds leads: it never activates a campaign or starts sending.
Support boundary
API-key connection
directThe key is validated against lemlist, stored encrypted per Argorant user, and revocable from Integrations.
Campaign selection
directList the connected workspace's existing campaigns and select one explicit destination.
Valid-only push
directPush only completed export rows classified as valid; missing verification status stops the job.
Reconciliation
directPoll the push job for total, pushed, skipped, failed, and last-error state.
Run it in this order
- 1Connect the workspace
Paste a lemlist API key in Profile → Integrations and confirm Argorant can list the intended campaigns.
Expected: A scoped, encrypted, revocable connection. - 2Choose the exact campaign
Open a completed export, select lemlist, and pick the destination campaign by name and ID.
Expected: No ambiguous or inferred campaign destination. - 3Push valid rows
Confirm the handoff. Argorant filters to valid rows, maps the lead fields, and uses provider and job idempotency guards.
Expected: Eligible leads are added once without changing campaign state. - 4Reconcile before send
Review pushed, skipped, failed, and last-error totals, then inspect the campaign in lemlist before activating it yourself.
Expected: A complete auditable handoff with sending still under operator control.
Confirm the audience before handoff
The matching count is visible before contact output. Check it and a masked sample before a paid export or destination push is allowed.
Before calling this complete
- Test success, local duplicate, provider duplicate, wrong campaign, 401, 403, 404, 429, 5xx, idempotent replay, and revocation.
- Confirm the campaign receives only valid rows and that a missing Verify Status column stops the job.
- Inspect provider calls to confirm there is no campaign activation, launch, or send request.
Hard boundaries
- Do not imply that connecting or pushing automatically activates a lemlist campaign or starts send.
- Do not imply that unknown, catch-all, invalid, or missing-status rows can pass the valid-only gate.
- Do not promise that lemlist entitlements, sending capacity, or campaign configuration are included with Argorant.
- Do not import unknown, catch-all, invalid, suppressed, or duplicate records into a valid-only campaign.

Yes. Connect a revocable lemlist API key, select an existing campaign, and push a completed valid-only Argorant export directly into it.
No. The connector only adds leads. Sequence content, schedules, campaign activation, and sending remain explicit actions inside lemlist.
Argorant checks the addresses when the export is created and keeps valid, catch-all, and unresolved outcomes distinct. That removes the need for an automatic second pass in many workflows, but it is not a guarantee that no mailbox can change before sending.
Argorant uses a destination-scoped idempotency key and email deduplication. A retry reconciles the same export and campaign instead of creating a second uncontrolled batch.
Nothing - counts and previews are free. Credits are spent only on reveals and exports.
