own your list
CSV export anytime. Your subscribers are yours — move them to any email tool whenever you want. No lock-in.
the page still does everything else
Themes, sections, scheduling, embedded YouTube/Spotify players, tip jars, per-block analytics with views and CTR — the form is one block among many.
the case for the list.
Platforms change reach overnight. The email list you collect from your bio page is the one audience no algorithm can take away.

Bio page + email capture + broadcasts in one place — instead of a bio tool, a form service, and an email platform duct-taped together.
questions.
Can I collect email subscribers from my bio page?
Yes. c3.lt bio pages include a built-in signup form block (Pro). Visitors subscribe right on the page; you see the list in your dashboard, can export it as CSV, and can send broadcast emails to it.
Can I email my subscribers from c3.lt?
Yes — broadcast emails send a one-shot message to your entire list from the dashboard. Every email carries a signed one-click unsubscribe link, handled automatically.
Can I export my subscriber list?
Yes, as CSV, anytime. The list is yours — you can import it into any email platform later. There is no lock-in.
Is there a subscriber limit?
Email subscribers and broadcasts are Pro features. The bio page itself — themes, links, embeds, tip jars, QR — starts on the free plan, so you can build the page first and add capture when you are ready.
How is this different from Linktree?
Most bio tools treat email capture as a premium add-on with the list living in their system. c3.lt puts the form on your page, gives you the list as a CSV, adds broadcasts, and pairs it with per-block analytics (views, clicks, CTR) so you can see how the form itself performs.
