How to Add New Houseler Customers to Your Email List Automatically

Repeat business is where the money is for a service company — and email is how you earn it. But your email list only grows if every new customer actually makes it onto it, and typing them in by hand never lasts.

This Zap does it for you: every new Houseler customer is added to your email tool automatically. We'll use Mailchimp, but the same steps work for any email app on Zapier.

Early access. The Houseler + Zapier app is in early access — email hello@houseler.com for an invite. New here? Start with How to Connect Houseler to Zapier.

What you'll build

• Trigger: Houseler → *New Customer*
• Action: Mailchimp → *Add/Update Subscriber*

Step 1 — Trigger on a new Houseler customer

1. Create a Zap; choose Houseler → New Customer.
2. Connect Houseler with your API key (Settings → Integrations) and test to pull a recent customer.

Step 2 — Add them to Mailchimp

1. Add the action Mailchimp → Add/Update Subscriber and connect your account.
2. Choose your audience, then map: - Email → email - First name → firstName - Last name → lastName - (optional) Phone → phone
3. Test, then turn the Zap on.

Good to know

• Customers without an email get skipped. Not every Houseler customer has an email on file. Add a Filter → "Email exists" step so the Zap only runs when there's an address to add.
• Not on Mailchimp? Swap the action for your tool — the same trigger feeds ConvertKit, Brevo, Klaviyo, Google Contacts, or a plain Google Sheet.
• Timing: Houseler checks for new customers every few minutes and runs the Zap automatically.

Make it a welcome

Point the Zap at a Mailchimp automation (or add a "send email" step) so every new customer gets a friendly welcome and your booking link — turning a one-time job into a repeat one.
