What Lemlist does really well
Lemlist is a reference in B2B cold email. Its strength: visual personalization, with images or screenshots customized to the prospect's name and company. For a sales team that wants to scale email campaigns with a genuine personal touch, Lemlist is excellent.
The tool also comes with a full ecosystem: built-in prospect database, detailed analytics, open and click tracking. It is designed for sales professionals who want full control over every step of their sequences.
The bottom line: Lemlist is excellent for those who already know how to prospect. If you still have to learn, you are paying for the tool and the learning curve. With Formula., you receive qualified prospects from day 3.
Posts + comments: the 3x multiplier
Formula. also generates LinkedIn posts and comments by AI. A prospect who sees your content before receiving a direct message converts 3 times more into a meeting. Formula. also does competitor monitoring: it spots the best-performing content from your competitors or sector influencers, and rewrites it in your style.
Calendar, mobile app, and continuous learning
When a prospect is ready to meet, the agent checks your calendar availability, proposes time slots directly in the conversation, and books the meeting automatically. No back-and-forth. The mobile app lets you validate agent actions with a swipe in seconds. The agent learns from every response: each validation or dismissal sharpens its targeting, messages, and follow-up timing. The more you use it, the better it gets.

FAQ
What is the main difference between Formula. and Lemlist?
Lemlist is an outreach tool: you build the sequences, write the messages, manage the campaigns. Formula. is an autonomous AI agent that identifies prospects on LinkedIn, detects interest signals, generates messages, sends and follows up automatically. One is a tool. The other is an agent.
Can Formula. import my prospect lists?
Yes. Formula. can work from lists you import. It can also identify targets on its own by detecting real-time interest signals on LinkedIn: profile visits, likes, comments in your sector.
Is Lemlist right if I do not have cold email expertise?
Lemlist requires real mastery of deliverability, copywriting, and segmentation. Without those skills, results will be disappointing. Formula. is designed to work without prior expertise.
Does the agent book meetings automatically?
Yes. The agent is connected to your calendar. When a prospect is ready to meet, it checks your availability, proposes time slots directly in the conversation, and books the meeting automatically. No scheduling back-and-forth.
How does Formula.'s continuous learning work?
Every validation or dismissal you make from the mobile app is a signal the agent integrates. It sharpens its targeting, copywriting, and follow-up timing continuously. Performance improves week after week without any reconfiguration on your part.
Do I keep control over what the agent does?
Your choice. The agent can run in full autonomy, or ask for your validation before each action. You set the level of control.
Is Formula. right for everyone?
No. Formula. is designed for entrepreneurs and business owners who already have a market-validated offer. If your offer sells and generates regular revenue, the agent can immediately go find new clients for you.
