ConvertKit (Kit) on Website Killer

ConvertKit (recently renamed Kit) is the email-marketing platform of choice for creators — newsletter writers, course sellers, indie SaaS founders. Cleaner segmentation than Mailchimp, stronger creator-focused features (paid subscriptions, sequences, tagging). On a Website Killer site, embed a Kit form via their hosted snippet or a custom form POSTing to their API. Free tier supports up to 10,000 subscribers (much more generous than Mailchimp).

Step-by-step setup

  1. 1

    Sign up at kit.com

    Free up to 10,000 subscribers. Connect your sending domain (or use kit.com's default).

  2. 2

    Create a form

    Kit → Grow → Landing pages & forms → New Form → Inline. Customize the form design or pick a template. Copy the embed code.

  3. 3

    Add the form to your Website Killer site

    Chat: 'Add a Kit (ConvertKit) email signup form in the hero'. Paste the embed code, or describe the form (e.g., 'with name and email fields, dark background, single CTA') and the AI builds it to POST to your Kit endpoint.

  4. 4

    Set up the welcome sequence

    Kit → Automate → Sequences → New. Build a 3-7 email welcome sequence. Trigger: 'Subscribes to form X'. Sequence runs automatically for every new subscriber.

    Optional: enable paid newsletters

    Kit → Earn → Settings → Connect Stripe. You can now offer paid subscriptions ($5-25/mo typically) right inside Kit. The Website Killer site links to the Kit-hosted paid signup page.

FAQ

Frequently asked questions

Is Kit's free tier really 10,000 subscribers?

Yes — Kit's free tier includes 10,000 subscribers, unlimited landing pages, unlimited forms, and unlimited broadcasts. Limitations: no automations on free (you can only send manual broadcasts), no sequences, no integrations. Paid plans start at $25/mo for these features.

Kit vs Beehiiv for newsletter writers?

Kit: better for course creators + creators who also sell paid products. Beehiiv: better for pure-newsletter writers who want growth features (referrals, recommendations, ad network). Both have similar pricing and integration ease.

Can I migrate my Mailchimp subscribers to Kit?

Yes — Kit has a free migration service. Export your Mailchimp audience as CSV, import to Kit, and Kit's team will set up your tags / sequences to match your Mailchimp segmentation.

Does Kit work for B2B SaaS marketing emails?

It can, but most B2B SaaS uses ConvertKit, Beehiiv, or HubSpot. Kit's creator-focused features (paid newsletters, content gating) are less useful for B2B than for indie creators. For B2B, default to Mailchimp or HubSpot unless you have a specific creator-economy fit.
