What is Lemlist?
Lemlist is a cold outreach and sales engagement platform designed for running multichannel campaigns and following up with leads at
scale. By integrating Lemlist with Konnectify, you can automatically add or update leads in campaigns, keep suppression lists in sync,
and trigger downstream workflows the moment Lemlist events occur.
This is especially useful for teams doing cold-email, outreach, lead management, and sales operations who want reliable, real-time
automation across their GTM stack.

API & authentication
Authentication method: API Key
Konnectify connects to Lemlist using an API Key. You’ll paste your Lemlist API key into Konnectify when creating a
connection. Keep this key private—anyone with the key can access your Lemlist account via the API.
What the connection enables:
- Receive real-time Lemlist events via webhooks
- Create/search/enrich leads and manage lead engagement status
- Create, fetch, update, and pause campaigns
- Manage campaign membership (add/update/remove/pause/resume/unsubscribe)
- Manage suppression via the unsubscribe list (add/remove email or domain)
Plan restrictions & rate limits
Lemlist API access and webhook availability may depend on your Lemlist plan. API rate limits can also apply; if limits are reached,
Konnectify will typically retry according to workflow settings. For high-volume outreach, consider batching and adding backoff in
your workflow design.
How to connect
Prerequisites
- An active Lemlist account
- Your Lemlist API Key
- Permission to create webhooks in Lemlist (for real-time triggers)
Add Lemlist to a Workflow
- Create a new workflow in Konnectify.
- Select Lemlist as your trigger app or action app.
Authorize via API Key
- When prompted, choose Add new connection.
- Paste your Lemlist API Key and save.
Configure the Trigger or Action
- Select the Lemlist event (trigger) or operation (action) you want to run.
- Map fields from previous steps (for example: email, campaign ID, lead attributes).
- For webhooks, Konnectify will provide a callback URL and handle subscription automatically where supported.
Important
For actions that affect campaign membership (add/update/remove/pause/resume/unsubscribe), ensure the campaign ID you map is
correct. Using the wrong campaign ID can modify the wrong sequence and impact live outreach.
Test the Workflow
- Run a test to verify authentication and field mapping.
- For the webhook trigger, generate a real Lemlist event to confirm it fires.
Activate the Workflow
- Turn the workflow on.
- Monitor the first few executions to confirm expected behavior.

FAQ
How does Konnectify authenticate with Lemlist?
Lemlist connections in Konnectify use API Key authentication. You provide your Lemlist API key once, and Konnectify
uses it to perform API requests and (where applicable) set up webhook-based triggers.
Which Lemlist plans are supported?
Most API-based functionality works on plans that include API access. Webhooks and certain campaign/lead endpoints may
require specific tiers. If an action fails due to permissions, verify your Lemlist subscription and API access in Lemlist.
How does the “New Lemlist Event” trigger work?
It’s a webhook trigger (real time). Lemlist sends event payloads to Konnectify as they happen, so you don’t need
polling intervals. This is ideal for time-sensitive workflows like routing replies or updating lead status immediately.
How do I prevent duplicates when adding leads to campaigns?
Use Search Lead (by email or lead ID) before Add Lead to Campaign. If the lead already exists,
branch your workflow to update/modify campaign membership instead of creating again.
What happens if Lemlist rate limits the workflow?
If the Lemlist API returns rate-limit responses, Konnectify will typically retry based on workflow settings. For sustained high
volume, add queuing/throttling steps, and avoid unnecessary enrichment calls (for example, only enrich when needed).
Can I connect multiple Lemlist accounts?
Yes. Create multiple Lemlist connections in Konnectify—one per API key/account—and select the appropriate connection in each
workflow step. This is helpful when you manage outreach for multiple brands or teams.
How should I handle compliance and suppression (unsubscribe) in Lemlist?
Use Add Recipient to Unsubscribe List to suppress an email address or domain across future sends, and
Unsubscribe Lead From Campaign to stop outreach within a specific campaign. If you need to re-enable sending to an
address (only when permitted), use Remove Email From Unsubscribe List.
