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.
