Mailchimp lets you collect email subscribers, send newsletters, and run automated email campaigns. If you want to build and nurture a mailing list from your Macaly site, Mailchimp is one of the most popular ways to do it.
Available on all plans
Do you actually need Mailchimp? Macaly has a built-in database and email notifications. If you just need a contact form or waitlist, you don’t need an external tool. Mailchimp is worth it when you need newsletters, drip campaigns, or audience segmentation.

​
Why use Mailchimp

  • Grow your list from your site. Collect subscribers and manage them in one place. Segment by interests, signup source, or behavior.
  • Send newsletters without touching code. Design and send email campaigns to your audience. Schedule them or send instantly.
  • Automate your follow-ups. Set up welcome emails, drip sequences, and abandoned cart reminders that run on their own.
  • See what actually works. Track open rates, click rates, and which links get the most engagement.

​
What you need

Before you start, make sure you have:
  • A Mailchimp account. Create one for free at mailchimp.com
  • A Mailchimp audience (mailing list) to collect subscribers into
There are two ways to connect Mailchimp to your site:
  • Embedded signup form. Paste Mailchimp’s generated form code into your site. Best for simple email collection.
  • Mailchimp API. Connect your forms to Mailchimp’s API for full control over what data you send. Best when you want custom forms that match your design.

​
Option 1: Embedded signup form

The simplest approach. Mailchimp generates a form you can drop into your site.
1

Get your form embed code

In Mailchimp, go to Audience then Signup forms then Embedded forms. Customize the fields you want, then copy the generated HTML code.
2

Ask the agent to add it

Open the chat in your Macaly project and ask:
3

The agent places the form

The agent adds the form to your project. You can tell it exactly where you want it, like the footer, a dedicated page, or a popup.
If you want the form to match your site’s design, tell the agent: “Style the Mailchimp form to match the rest of my site.”

​
Option 2: Custom form with Mailchimp API

For more control, the agent can build a custom form that sends subscribers to Mailchimp through their API.
1

Add your Mailchimp credentials to Secrets

Go to Settings then Secrets in your Macaly project. Add two secrets:
  • MAILCHIMP_API_KEY — your Mailchimp API key
  • MAILCHIMP_AUDIENCE_ID — the audience you want subscribers added to
API key:
  1. In Mailchimp, click your profile icon, then Account & billing
  2. Go to Extras then API keys
  3. Click Create a key and copy it
Audience ID:
  1. Go to Audience then All contacts
  2. Click Settings then Audience name and defaults
  3. Your Audience ID is listed on this page
2

Ask the agent to build the form

Open the chat and ask:
Never paste API keys directly into the chat. Always use Settings then Secrets to store sensitive credentials. The agent can read them from there securely.

​
Verify it’s working

1

Submit a test signup

Visit your site and enter a test email address in the signup form.
2

Check your Mailchimp audience

Go to Audience then All contacts in Mailchimp. Your test email should appear as a new subscriber.

Good to know

  • If you only need to collect emails, Macaly’s built-in database is simpler and doesn’t require an external account
  • For GDPR compliance, enable double opt-in in your Mailchimp audience settings. This sends a confirmation email before adding someone to your list
  • The agent can also set up pop-up forms and slide-in forms if you want something more prominent than an inline signup
