lemlist

lemlist is a multichannel prospecting platform known for personalized cold outreach. It started with cold email and now runs sequences across email, LinkedIn, calls, SMS and WhatsApp from one campaign, so you can reach prospects wherever they respond.

Built-in lead data is a big part of the product: an email and phone finder and a database of more than 650 million leads let you build lists without another tool, and data add-ons bring enrichment from 25 or more providers and buying-intent signals such as hiring, funding and technology changes. lemlist's AI agents, including lemAgent, help with enrichment, messaging and signals, and a deliverability hub with lemwarm warm-up protects your sender reputation. It connects to CRMs and supports MCP and a CLI for AI workflows.

It suits founders, sales teams and agencies that want personalized multichannel outreach rather than pure email volume.

The Email plan costs $69 a month, or $55 billed yearly, with unlimited users and email senders and 50,000 emails a month. Multichannel is $109 per user a month, or $87 billed yearly, and adds LinkedIn automation, SMS, WhatsApp and a dialer. Enterprise is custom. There is a 14-day free trial with no credit card.
