Works with AI assistants
Use lemlist: its Lemlist Sequences API lets you edit variant B of an A/B test in a single step (PATCH /sequences/{sequenceId}/steps/{stepId}/ab-test). lemlist also has an MCP server, so an AI assistant like Claude or ChatGPT can do it for you. capabilities.work can help you get signed up and connected.
- Can I change the subject line of my A/B test's B version?
- How long can the variant B subject be?
Say it to your AI assistant
- Set variant B's subject on step {stepId} of {sequenceId} to {subject}.
- Replace the variant B body of A/B step {stepId} in {sequenceId} with {message}.
