Multichannel outbound sales platform with AI agentic enrichment and signals
Last reviewed 2026-06-20
Lemlist (built by Lempire) is a multichannel sales engagement platform built around personalized cold outreach at scale: a 650M+ lead database with waterfall enrichment, email and LinkedIn finder/verifier tools, multichannel sequences (email, LinkedIn, calls, WhatsApp, SMS), a unified inbox, and email deliverability/warmup via lemwarm. On top of that core it layers AI: AI-generated sequence copy and personalization (icebreakers, dynamic images, video thumbnails), plus agentic features for enrichment and timing. Lemlist targets SMB and mid-market sales teams, agencies, and founders running outbound. Its 2025-2026 AI push includes agentic enrichment (autonomous agents that scrape pages, cross-reference CRM data, and run waterfall enrichment across multiple data providers), signal-triggered campaigns (buying-intent events that auto-launch personalized sequences), and a 'smartbound' direction following its October 2025 acquisition of conversation-intelligence platform Claap. The action-taking parts run inside human-configured campaigns, so they are treated as supervised agents. Lempire is bootstrapped and profitable.
What it can do
Generate multichannel sequences and personalization (AI copy)

sourceAgentic lead enrichment (waterfall across data providers)
SupervisedLemlist describes autonomous AI agents that scrape web pages, pull data from LinkedIn, websites, and CRMs, cross-reference existing CRM data, and run waterfall enrichment across multiple data providers to build structured variables for segmentation and personalization.
sourceSignal-triggered campaigns (buying intent)
SupervisedSignal agents track buying-intent events (hiring, funding rounds, job changes, website visits, LinkedIn engagement) and automatically trigger campaigns at the moment a prospect is most likely to engage, with messaging personalized to the signal context.
sourceWarm up inboxes and protect deliverability (lemwarm)
Supervisedlemwarm runs an automated peer-to-peer warm-up network (reportedly 10,000+ active users) to gradually build sender reputation, with domain health monitoring and deliverability tooling included on every paid seat.

Overview
Lemlist (built by Lempire, Paris) is a multichannel sales engagement platform built around personalized outbound at scale. It combines a 650M+ B2B lead database with waterfall enrichment, email/LinkedIn finder and verifier tools, multichannel sequences (email, LinkedIn, calls, WhatsApp, SMS), a unified inbox, and email deliverability/warmup via lemwarm, then layers AI on top. It is popular with SMB and mid-market teams, agencies, and founders, and Lempire is bootstrapped and profitable.
What it does
Lemlist's AI generates email copy, icebreakers, and full multichannel sequences from a product description, target persona, and campaign goal, which is copilot-grade (the user reviews and edits). Its 2025-2026 agentic features go further: agentic enrichment deploys autonomous agents that scrape pages, pull from LinkedIn/websites/CRMs, cross-reference existing CRM data, and run waterfall enrichment across multiple data providers; signal agents track buying-intent events (hiring, funding, job changes, website visits, LinkedIn engagement) and auto-trigger personalized campaigns at the right moment. Personalization includes dynamic images with prospect names and company logos, custom video thumbnails, and liquid-syntax branching by role or industry. Because these action-taking features run inside human-configured campaigns and rules, they are treated as supervised agents rather than fully autonomous outreach.
Integrations & setup
Native connections to HubSpot, Salesforce, and Pipedrive, plus Zapier and Make for triggers, Slack for notifications, and Gmail/Outlook for sending. LinkedIn is a first-class channel (connection requests, profile visits, messages). Lemlist exposes a REST API. lemwarm warm-up is included on every paid seat. Reported integrations suggest the platform uses Anthropic Claude and OpenAI GPT models for sequence generation (reported, not officially detailed).
Pricing
Per-seat subscription. The Email plan starts at $69/mo per seat ($55/mo billed annually) with 50,000 emails/month; the Multichannel plan (LinkedIn, SMS, WhatsApp, and dialer) starts at $109/mo per seat ($87 annual) with unlimited emails and messages; Enterprise is custom-quoted for teams of 5+ and adds SSO/SAML and a dedicated account manager. Pay-per-success lemlist credits (roughly $0.01/credit: 5 credits per verified email, 20 per phone number, 20-100+ per intent signal) are billed on top, so real spend runs above the headline price. A 14-day free trial is available with no credit card required.
Best for / not for
Best for SMB and mid-market teams and agencies that want genuine multichannel outreach (email plus LinkedIn, calls, WhatsApp, SMS) with built-in warmup, strong visual personalization, and signal-based triggering in one platform. Less suited to teams wanting a single flat bill (credits stack on top), enterprise-grade sales engagement at the scale of Outreach/Salesloft, or fully hands-off autonomous outbound (Lemlist's AI is copilot/supervised by design).
Alternatives
Instantly is the closest cold-email-first peer (warmup plus AI agents) at a lower entry price; Apollo bundles a large database with sequencing and a free tier; Clay focuses on enrichment and list building; Outreach and Salesloft are enterprise sales engagement platforms.
