lemlist: what it costs at your list size, its AI and its terms

What lemlist is

lemlist is a cold outreach tool. You load a list of people who have not signed up to hear from you. It sends them a sequence: a first email, then follow-ups, a LinkedIn message or a call reminder, each step timed and personalised.

That sets it apart from a newsletter platform such as Brevo or MailerLite, which mail people who opted in. On top of sending, lemlist sells access to a lead database it puts at 650M+ contacts, plus an email and phone finder. It also includes lemwarm, a warm-up service that builds a new mailbox’s sending reputation (pricing page).

There is no free plan. The FAQ offers a 14-day trial with Multichannel features and 200 free credits. The AI email marketing hub places lemlist beside the other 14 email tools we track.

What lemlist costs at your list size

lemlist puts no cap on contacts. Both paid plans list “Unlimited contacts”, so list size does not change the price of the 50,000-email tier the page prints. What you pay for is how much you send, or how many people on your team send.

The Email plan costs $69 a month at 50,000 emails a month, the one volume tier the pricing page prices.

Put that volume in leads. A three-step sequence sends three emails to each new lead, so the plan covers about 16,700 new leads a month. At 50,000 contacts in one month you pass the published tier, which is why the 50,000 cell above reads empty.

Multichannel lifts that ceiling. It costs $109 a month per user and lists unlimited emails and messages, with five senders (connected sending mailboxes) per user. The lemlist pricing page works through team sizes, yearly billing and every add-on.

Which lemlist plan has the AI agents

lemlist’s AI runs as agents: tools that research a lead, enrich the record and draft the message for you. The Email plan card lists lemAgent and “Signal, Enrichment, & Messaging AI agents”, so the AI sits on the cheapest plan.

The writing assistant has a named engine. lemlist’s AI page says AI Copilot is powered by Claude, made by Anthropic. AI Columns run OpenAI, Perplexity, Claude or Gemini models on each lead’s details, for example to write a first line from a company’s website.

The running cost is clear: the agents that look up data spend credits, and credits are sold apart from every plan.

Does lemlist train AI on your list

The terms do not say. No clause in the General Terms (dated 17 September 2025), the privacy policy or the AI page says lemlist trains models on your contacts. None says it does not.

Two clauses frame the question. Article 12 lets lemlist use your data “only for the purpose of providing the service (and for no other purpose)”.

Terms of Service, 12

Your acceptance of this ToS gives us the permission to do so and grants us any such rights necessary to provide the service to you, only for the purpose of providing the service (and for no other purpose).

Article 7.5 is wider: where your non-personal data is protected by an intellectual property right, you grant lemlist a right to use it “for an unlimited period after the end of the Agreement”.

Your leads also reach outside AI providers when you use AI Copilot or AI Columns. The AI page names Anthropic, OpenAI, Perplexity and Gemini. The AI-training guide sets lemlist’s clauses beside the other 14 tools.

Contact counting and deliverability traps

The first trap is the seat. On Multichannel, “Pricing is based on the number of users” (FAQ), so each salesperson adds a full plan. The Email plan allows unlimited users and senders, which makes it the cheaper route for a team that only sends email.

The second is data. Uncapped contacts do not mean free contacts: finding an email address or phone number spends credits. The pricing FAQ says 2,000 credits cover 400 emails or 100 phone numbers. Unused credits roll over while you subscribe.

Deliverability is whether your email lands in the inbox or the spam folder. Every plan includes lemwarm warm-up and a deliverability hub, and the comparison table lists rotating IPs on all three plans. No dedicated IP add-on appears on the page.

lemlist reviews praise support; pricing draws the sharpest complaints

We read 14 public user sources dated 4 March to 30 October 2026: 10 Trustpilot reviews and four Reddit posts. On Trustpilot, 82% of 255 reviews give the top mark and 11% the lowest.

Support leads by a distance: 6 of the 14 sources, all on Trustpilot, praise it for speed or care (Trustpilot, Trustpilot). A Reddit team that sent over 100,000 emails says personalisation is where lemlist stands out (1 of 14 sources, Reddit).

Email finding stands out in one comparison. On 1,000 leads, lemlist’s waterfall (a chain of 25+ data providers asked in turn) found 94.1% of emails, ahead of Apollo and Hunter. It took 11 minutes against under 4 for Apollo (1 of 14 sources, Reddit).

The complaints are few but specific. One Trustpilot reviewer says the Multichannel plan included less than its advertising implied, costing more than $600 a year (1 of 14 sources, Trustpilot). The Reddit team that sent 100,000+ emails calls lemlist pricey at volume (1 of 14 sources, Reddit). Another Trustpilot reviewer calls cancelling hard (1 of 14 sources, Trustpilot).
