Mailchimp on Website Killer

Mailchimp is the most-used email marketing platform — solid for small-to-mid lists (under 50K subscribers). On a Website Killer site, embed a Mailchimp signup form via their hosted form snippet, or wire up a custom form that POSTs to Mailchimp's API. Hosted form takes 5 minutes; custom form takes 15-30 minutes. Free tier supports up to 500 contacts.

Step-by-step setup

  1. 1

    Create a Mailchimp account

    mailchimp.com → Sign up. Free tier doesn't require credit card. Create your first audience (your subscriber list).

  2. 2

    Build an embedded signup form

    Mailchimp Dashboard → Audience → Signup forms → Embedded forms. Choose 'Classic' for the simplest version. Mailchimp generates HTML you can copy.

  3. 3

    Add the form to your Website Killer site

    Open chat: 'Add a Mailchimp email signup form in the footer'. Paste the Mailchimp HTML when prompted, or describe what you want and the AI builds a form that POSTs to your Mailchimp endpoint. Publish.

  4. 4

    Test the signup flow

    Subscribe yourself from the live site. Check that you appear in the Mailchimp audience within 1-2 minutes. Confirm the welcome email (if you've set one) lands in your inbox.

  5. 5

    Set up a welcome automation

    Mailchimp Dashboard → Automations → Add → Welcome email. New subscribers get an automatic welcome email; you can add a 5-email onboarding series to nurture them into customers.

FAQ

Frequently asked questions

Mailchimp vs ConvertKit vs Beehiiv?

Mailchimp: most general-purpose, ok for ecommerce + B2B + B2C blend. ConvertKit: best for creators, course-sellers, and indie SaaS (creator-focused features). Beehiiv: best for newsletters (paid newsletter support, growth-focused features). All three integrate with Website Killer via embedded forms.

Can I use a custom form design with Mailchimp?

Yes. Mailchimp provides an HTML form action URL; you can wrap any form in your custom design and POST to that URL. The chat editor handles this — describe the design and the AI builds it to match.

How do I avoid spam signups?

Two options: (1) Enable double opt-in in Mailchimp settings — new subscribers must click a confirmation email before being added to the list. Standard for GDPR/CCPA compliance and reduces bot signups. (2) Add Cloudflare Turnstile or hCaptcha on the form for additional bot protection.

Can I trigger emails based on site events?

Yes via Mailchimp API. Fire a 'page_viewed' or 'purchase_completed' event to Mailchimp, then trigger a tagged automation. This is more advanced — export your site source and add the API call server-side. For simpler needs, the embedded form + welcome automation handles 80% of use cases.
