Integrations

Native CRM Integrations

Lemlist offers direct integrations with the most popular CRMs used by sales teams. These native integrations require no coding and sync automatically.

HubSpot Integration

The HubSpot integration is Lemlist's most complete CRM connection. It provides full two-way sync: contacts flow from HubSpot to Lemlist campaigns, and all email activity (opens, clicks, replies) syncs back to HubSpot contact records. You can trigger campaigns based on HubSpot lists or workflows, and replies automatically create tasks or update deal stages.

Salesforce Integration

Salesforce users can connect their org to push leads into Lemlist campaigns. Activity syncs back to the lead/contact record timeline. Works with Salesforce Essentials, Professional, Enterprise, and Unlimited editions. Setup requires admin access to create a connected app.

Pipedrive Integration

The Pipedrive integration syncs contacts, creates deals on positive replies, and logs all email activity to the person timeline. You can filter which contacts to import based on pipeline stage or custom filters. This is ideal for sales teams using Pipedrive as their primary CRM.

Automation Platforms

For custom workflows beyond native integrations, Lemlist works with popular automation platforms.

Zapier Integration

Zapier offers 50+ triggers and actions for Lemlist. Popular Zaps include adding leads from Google Sheets, syncing with Airtable, posting to Slack on replies, and connecting to CRMs without native integrations. Zapier is beginner-friendly but can get expensive at scale (plans start at $20/month).

Make.com Integration (Recommended)

Make.com (formerly Integromat) provides more powerful workflows at lower cost. You can build complex multi-step scenarios with conditional logic, data transformations, and error handling. Make is 5-10x cheaper than Zapier for high-volume workflows. I use Make for all my client integrations because of its visual workflow builder and robust error handling.

Common Make scenarios with Lemlist:

• Enrich leads with Clay or Clearbit before adding to campaign
• Route replies to different Slack channels based on sentiment
• Create CRM deals with custom fields populated from email content
• Sync unsubscribes to a master suppression list
• Trigger follow-up campaigns based on engagement behavior

Webhooks for Developers

Lemlist provides real-time webhooks for all email events. This is the most flexible option for custom integrations with your own systems.

Available webhook events:

• emailSent — When an email is sent
• emailOpened — When recipient opens (with IP, device info)
• emailClicked — When a link is clicked (includes URL)
• emailReplied — When prospect replies
• emailBounced — Hard or soft bounce
• emailUnsubscribed — When someone unsubscribes
• leadInterested — Marked as interested in Lemlist
• leadNotInterested — Marked as not interested

Webhook payloads include full lead data, campaign info, and event metadata. You can set up multiple webhooks per event type with different destination URLs.

Lemlist API

Lemlist provides a REST API for programmatic access. You can create campaigns, add leads, check stats, and manage sequences via API calls. The API is well-documented and supports both personal API keys and OAuth for multi-tenant applications.

API use cases include building custom dashboards, bulk lead imports from proprietary systems, and automated campaign management based on external triggers.

Recommended Integration Stack

Based on my work with 50+ clients, here's the integration stack I recommend:

• CRM: Native Pipedrive or HubSpot integration
• Automation: Make.com for custom workflows
• Enrichment: Clay → Lemlist via Make.com
• Notifications: Slack via Make.com (filtered by reply type)
• Suppression: Webhook to master list for compliance
