lemlist

lemlist is an AI-powered sales outreach platform that helps businesses find potential customers (prospects), personalize their messages, and send them automatically. Instead of juggling several different tools for finding leads, sending emails, and tracking results, lemlist brings it all into one place. It can search a database of over 600 million contacts, enrich them with verified email and phone numbers, and then run campaigns across email, LinkedIn, calls, WhatsApp, and SMS — all from a single workflow. Its AI agents research each prospect and tailor messages so outreach still feels personal, even when you're contacting thousands of people. It also includes tools to keep your emails landing in the inbox instead of the spam folder.
