Kit on your landing pages
Creators who buy traffic pay for every subscriber, so the list has to earn it back: through the course launch, the paid newsletter, the coaching call. Kit is built for that relationship. LanderLab is built for the paid page that starts it, with quiz funnels that learn what each subscriber wants before the first email goes out.
Each submit on a LanderLab landing page or quiz funnel is sent to Kit as a subscriber, with the answers in Kit custom fields. Inside LanderLab it's still listed under its old name, ConvertKit. The result is a list that's segmented from day one and a clear line from each ad to the subscribers it bought.
Kit subscribers from landing pages and quizzes
Email is the one field Kit requires, and anything else you collect can go to Kit fields, including the custom fields you've made. Each submit on the landing page or quiz funnel is then sent to Kit as a subscriber in real time.
Quiz answers in Kit custom fields that shape the emails
A paid quiz tells you what each subscriber wants before the first email goes out. Map the answers to Kit custom fields and you can build segments on them, send each segment the broadcast that fits, or drop an answer straight into the email with Kit's personalization.
The beginner and the expert who came in from the same ad don't have to get the same email.
Which ad brings subscribers who buy
Cost per subscriber is the number you see in Ads Manager. What matters is cost per buyer. With utm_campaign and LL Variant ID on each subscriber, a Kit segment shows which angle and which variant produced the people who bought the course or upgraded to paid, and you move budget accordingly.
Kit in a workflow, with a filter in front
ConvertKit is also an action in LanderLab Workflows (beta). Put a Filter node before it and only the leads you want reach Kit: finished quizzes only, or one country, with the rest stopping at the filter. The workflow's Runs view shows where each lead went, so a missing subscriber is a quick check, not a support ticket.
