Topline by Jacquard

Topline tells you how your marketing copy will perform before it goes out. Paste in your subject lines, preheaders, SMS, push notifications, ad headlines or social posts, and Claude checks them with Jacquard's Neural 2.1 model. Each line gets a verdict (Strong, Good or Needs work) and a 0–100 score, so you can send the version most likely to be clicked. Neural 2.1 is Jacquard's performance model, the same technology enterprise brands use through Jacquard to predict what their customers will click. Topline puts it in your AI assistant, for email, SMS and ad marketers of any size. Write a few options with Claude, ask it to check them with Topline, and keep the winner. After the send, Claude can share the results back (total sends and clicks, plus opens and revenue if you have them), and Topline shows them next to its earlier verdict so you can see how the prediction held up. Topline never asks for subscriber lists, email addresses or recipient-level data. Your drafts and results stay in your Topline workspace.
