Lemlist

What this skill does

The Lemlist skill enables cold email outreach with advanced personalization and comprehensive campaign management. It connects to Lemlist’s REST API to create, monitor, and adjust email campaigns, manage leads, track activities like opens and replies, and handle unsubscribes. This skill provides access to detailed campaign statistics and real-time webhook events, allowing marketers to optimize outreach based on engagement metrics.

Who it's for

This skill is designed for performance marketers running outbound email campaigns seeking scalable personalization and precise lead control. Growth leads managing multi-channel acquisition funnels benefit from integrating email outreach data with other channels. Agencies focused on link building or B2B appointment setting use Lemlist to automate prospecting while maintaining a personalized touch in messaging.

Key workflows

Practitioners start by listing and reviewing active campaigns to evaluate open and reply rates. Next, they add or remove leads within campaigns to refine targeting and avoid wasting impressions on unresponsive contacts. Monitoring email activities by type, such as emails opened or replied, helps assess campaign effectiveness. Finally, teams set up and manage webhooks to receive real-time notifications on events, enabling immediate follow-up or integration with CRM systems.

Common questions

How do I authenticate API requests? Use Basic Auth with an empty username and your API key as the password in the Authorization header. Can I track lead engagement per campaign? Yes, you can fetch detailed statistics and activity logs filtered by campaign and event type. What are the API rate limits? Rates vary by plan, but staying under 10 requests per second is recommended to avoid throttling.

How to use in Metaflow
