Inside lemlist AI: Agents, SMS, and MCP
lemlist has shipped four things in the last stretch worth understanding on their own terms, not as marketing bullet points. Here is what each one is actually for, in order of how likely you are to need it.
lemlist has shipped four things in the last stretch worth understanding on their own terms, not as marketing bullet points. Here is what each one is actually for, in order of how likely you are to need it.
lemAgent takes a plain language goal, something like "find 50 marketing directors at Series B SaaS companies in Europe and write a cold email about our design tool", and handles the two most time consuming parts of setting up a campaign: sourcing the list and drafting the first pass of the copy.
It does not replace judgment. The leads it finds still need a quick review for fit, and the copy it drafts still benefits from a human edit pass before it goes out, the same way a first draft from a junior copywriter would. What it removes is the blank page problem: instead of starting from nothing, you start from a reasonable first version and edit down from there.
Worth turning on for: anyone who currently spends the first hour of building a campaign just assembling the list and staring at an empty email draft.
Adding SMS as a step inside a sequence works differently than email or LinkedIn. Text messages get opened within minutes in most cases, which makes the channel useful for time sensitive moments: a meeting reminder, a fast follow up after a demo, a nudge on a proposal with a deadline, rather than as a first-touch cold channel.
Used as a cold opener, SMS reads as intrusive fast. Used two or three steps into a sequence, after some context has already been established by email, it reads as a reasonable nudge instead. The distinction matters more than the feature itself.
Worth turning on for: teams with sequences long enough to have a genuine time sensitive moment worth a text, not for cold volume outreach.
This is a set of pre-built skills that let an AI assistant carry out lemlist workflows directly, for example pulling campaign performance or managing sequence steps, from inside a chat conversation instead of the lemlist dashboard itself.
The practical use case is narrower than the other three: it matters most if you already do a meaningful chunk of your daily work inside an AI assistant and want campaign management to happen in the same place, rather than switching tabs to check on a sequence.
Worth turning on for: people who already run most of their workday through an AI assistant and want one less tab open.
MCP (model context protocol) is the standard that lets an AI assistant like Claude or ChatGPT talk to an external tool like lemlist directly. The Claude skills above are built on top of this connection. If you are not using an MCP-aware assistant day to day, this layer is invisible to you, and that is fine. It is infrastructure rather than a feature you interact with directly.
Worth understanding if: you are technical and curious about how the Claude skills integration actually works under the hood. Otherwise, skip straight past this one.
Pick one live campaign you already run manually. Rebuild just the list and first email draft with lemAgent, then compare edit time and reply rate against your baseline. If the draft saves more than 30 minutes per batch and reply rate holds, keep it. If not, turn it off for that campaign type and try again on a simpler offer.
If you only try one, make it lemAgent. It is the one with the broadest use case, cutting the setup time on every future campaign, while SMS and the Claude integration matter more for specific workflows once the basics are already running well.

|---|---|---|
| lemAgent | The first hour of list building and blank-page copywriting | You launch campaigns regularly |
| SMS prospecting | Missed time-sensitive moments mid-sequence | Your sequences have genuine urgency points |
| Claude skills | Tab-switching to check campaigns | You already work inside an AI assistant daily |
| lemlist MCP | Nothing directly - it is the plumbing | Only relevant if you are technical and curious |
lemAgent and the AI writing assistance are included in the plans rather than sold as separate add-ons, though usage-based features like SMS sending carry per-message costs. Check the live pricing page for the current breakdown before budgeting a campaign around any of them.
Not inherently. Providers filter on sender reputation and engagement, not on whether a human typed the words. What does hurt is sending identical AI output to hundreds of people, which recreates the template problem AI was supposed to solve. Edit every draft so each message stays genuinely specific.
MCP is an open protocol, so any assistant that supports it can connect in principle. The packaged skills are built for Claude specifically, but the underlying connection is not exclusive to one assistant.
None of the four replace the fundamentals covered in our other guides. A well sourced list, a personalized sequence, and a warmed up sending domain still matter more than any single AI feature. These additions save time on tasks that used to take an hour; they do not substitute for getting the sequence itself right. See our guide to personalized cold outreach for the fundamentals these features are built on top of.
Every feature above is included from the free trial, no separate add-on purchase required to test them.
