lemlist

Fetch a paginated list of every activity event logged against a lemlist account — clicks, opens, replies, and custom events all in one pull.

Push enrichment data — job title, company size, LinkedIn URL — into an existing lemlist lead record to sharpen personalisation before the sequence fires.

Look up a verified business email address for a named person at a given company domain directly from lemlist's finder.

Read per-campaign metrics — open rate, click rate, reply rate, bounce count — for a given lemlist campaign ID.

Retrieve a verified direct-dial or mobile number for a lead — useful for Aircall or manual follow-up sequences that mix email and phone.

Fetch enrichment profile data — company, industry, headcount, LinkedIn — for a person using lemlist's built-in enrichment engine.

Tag a lead as Interested across every campaign they're enrolled in simultaneously, preventing duplicate outreach and signalling CRM handoff readiness.

Flag a specific lead as Interested within a single named campaign, pausing that sequence while leaving other campaigns for the same lead running.

Run lemlist's enrichment pipeline on a person record and write the result back — updating email, phone, LinkedIn, job title, and company size in one pass.

Enroll an existing lead record into a named lemlist campaign and start the sequence from step one.

Create a brand-new lead record in lemlist with full contact fields — first name, last name, email, company, custom variables — ready for campaign enrolment.

Apply a Not Interested flag to a lead across every lemlist campaign in one call, immediately halting all active sequences and protecting the contact from further outreach.

Permanently remove a lead record from lemlist, stripping all contact data and sequence history — use for hard GDPR erasure requests.

Stop outreach for a lead within a single campaign while leaving them active in any other sequences they're enrolled in.

Temporarily suspend a lead's progress in all campaigns (or a named subset) without losing their sequence position — resume picks up from where they left off.

Add a lead record to lemlist's global unsubscribe list directly via the Lead resource, stopping all future outreach at the record level.

Extract a lead from a specific campaign mid-sequence without deleting the lead record or affecting other enrolments.

Reinstate a previously unsubscribed lead so they can be re-enrolled in campaigns — typically used after a verified re-consent flow.

Read the current enrichment and finder credit balance for the team's lemlist account to prevent mid-campaign credit exhaustion.

Restart a paused lead's sequence from where it stopped — across all campaigns or a named subset — without re-enrolling from step one.

Add an email address directly to the lemlist team's unsubscribe list via the Unsubscribe resource — skips the lead record lookup.

Mark a lead as unsubscribed via the General resource path, halting all outreach and adding them to the team suppression list in one call.

Push a recipient's address to the global unsubscribe list via the General endpoint — useful when the outreach originated outside a lemlist lead record.

Patch custom variables, email, or status fields on a lead's campaign-level record without affecting their global lead data or other enrolments.

Fires on every lemlist event type at once — a catch-all webhook useful when you want a single agent to route different activity types through conditional logic.

Fires via webhook the moment any campaign activity is recorded in lemlist, delivering the event payload in real time for low-latency automation.

Fires when a new Aircall call is created for a lemlist lead, signalling the start of a phone-step touchpoint in a multichannel sequence.

Fires when a recipient clicks the unsubscribe link in a lemlist email, allowing immediate cross-system suppression before the next campaign step runs.

Fires after an Aircall step in a lemlist sequence completes successfully, indicating the dial was placed and a disposition was logged.

Fires immediately when an Aircall phone session terminates, regardless of outcome — useful for capturing call duration and triggering post-call workflows.

Fires when a lemlist lead is marked Interested following an Aircall phone step, signalling confirmed warm intent from a voice interaction.

Fires when a lemlist lead explicitly declines during an Aircall phone step, allowing the agent to close out the sequence and update pipeline health immediately.

Fires when an API-triggered step in a lemlist sequence completes successfully, confirming the external call or webhook payload was delivered.

Fires when an API step in a lemlist sequence fails — the external call returned an error or timed out — enabling immediate error handling and retry logic.
