What is lemlist

Vendor's own claim

lemlist is a sales engagement platform built around its own lead database and deliverability infrastructure.

Ideal customer profile

Vendor's own claim

Sales reps, founders, and revenue teams that want multichannel (not just email) outbound with a built-in lead database, ranging from solo operators on the Email plan to larger teams needing LinkedIn/SMS/call automation on the Multichannel or Enterprise plans.

Who should look elsewhere

Our read

LinkedIn automation, SMS, the call dialer, and task management are gated behind the Multichannel plan ($87/user/mo, or $109/mo billed monthly without the annual discount), so teams that only want email plus API access are paying $55/mo flat on Email but cannot get multichannel without moving to per-user pricing. Email- and phone-finding, and buying-intent signals, are metered separately as paid credits (from $10/1,000 credits) on top of the subscription, so high-volume enrichment use gets expensive quickly. SSO/SAML and custom user roles are Enterprise-only (5+ users), so smaller teams needing enterprise security controls are underserved.

lemlist FAQ

Does lemlist have an MCP server for AI agents?

From official docs
How is lemlist priced?

Email plan at $55/mo flat with unlimited users and 50,000 emails/month; Multichannel at $87/mo per user adding LinkedIn, SMS, WhatsApp (add-on), and calling; Enterprise is custom-priced for 5+ users with SSO/SAML and dedicated support.

From official docs
Are LinkedIn and SMS automation included on every plan?

No, they are Multichannel-plan features; the Email plan covers email outreach plus the lead database and AI agents, not LinkedIn/SMS/calling.

From official docs
Do lead-finding and intent signals cost extra?

Yes, they are metered as credits on top of the subscription: 5 credits per email found, 20 credits per phone number, at roughly $10 per 1,000 credits, with buying-intent signals costing 20-400+ credits depending on the signal type.

From official docs
Does lemlist publish an agent-skill or SDK repository on GitHub?

The developer docs describe MCP and REST API integration paths for AI agents but do not link to a vendor-published GitHub repository for either.

Our read
What email warmup tool does lemlist use?

lemwarm, lemlist's own built-in warmup and deliverability-monitoring tool, included as part of the deliverability hub.

  • Named list of MCP tool names (docs describe categories of tools, not an exact tool-name list)
  • Fixed numeric API rate limits
  • An X/Twitter account (a plausible handle exists but could not be verified as vendor-owned)
  • A vendor-linked GitHub organization
  • A stated trial length or trial policy on the pricing page
