A system that gets better with every send.
Recursion watches your campaigns in real time, finds what's working, and tells you exactly what to change, or changes it for you. The longer it runs, the sharper it gets.

Reframe the subject line around the outcome, not the feature
Subject lines referencing cost savings are converting at 3.2× vs. product-feature lines across this ICP. Try leading with the outcome instead.
Why Recursion flagged this
Four steps. One closed loop.
Recursion runs continuously in the background. Every campaign becomes training data for the next one.
Ingest- Takes in everything
Recursion reads every signal your campaigns produce: reply rates, open rates, click-through, bounce events, positive and negative sentiment in replies, and time-to-reply.
Analyse- Finds what's working
It compares performance across sequences, subject lines, audiences, and send times. Patterns that humans would take weeks to spot surface in hours.
Suggest- Proposes improvements
Specific, reasoned recommendations land in your dashboard: a new angle for a subject line, a tighter ICP filter, a different send window, a rewrite of the hook.
Apply- Closes the loop
You approve the change, or let Recursion apply it automatically. Either way, the updated logic feeds straight back into the next send cycle.
Every lever that moves the number.
