Lemlist

Lemlist turns outbound into precision work with AI agents that spot high-intent leads and trigger context-based campaigns. It enriches leads from a 650M+ lead database, imports from CRM or CSV, and uses an email and phone number finder to surface verified contacts. Signal agents track engagement events to time outreach, while enrichment agents pull context from LinkedIn, websites, and CRM to personalize each message.

What it does

Multichannel campaigns run across email, LinkedIn, calls, WhatsApp, and SMS from a single sequence, with a unified inbox for replies. A built-in Deliverability Hub monitors domain health, manages sending limits, and uses inbox rotation and smart sending to keep emails out of spam.
