Two ways to connect

Mailchimp works with Sticklight at two levels, depending on what you’re building.

Connector (for building)

The Mailchimp connector is one of several available connectors that extend your Sticklight projects. The Mailchimp connector lets Sticklight access your Mailchimp data while you build. Connect once and Sticklight can read your audiences, pull campaign stats, and show you live data in the editor.

Use this for: Dashboards, reports, engagement visualizations, anything that displays your Mailchimp data.

API key (for collecting submissions)

When you build something that writes to Mailchimp, like a signup form that adds subscribers, Sticklight needs your Mailchimp API key. This lets your published app send data to Mailchimp on behalf of visitors.

Use this for: Newsletter signup forms, lead capture, anything where your app’s visitors interact with Mailchimp.

Sticklight prompts you for the API key when it’s needed. You don’t have to set it up in advance.

Available data

Once connected, your project can access:

Data	What you get
Campaigns	Subject lines, send dates, open rates, click rates, revenue
Audiences	Subscriber lists, segments, tags, merge fields
Subscribers	Email addresses, engagement scores, activity history
Automations	Workflow performance, trigger counts, conversion data
Reports	Campaign comparisons, audience growth, engagement trends

Common use cases

Campaign leaderboard

Every campaign you’ve sent, ranked by the metrics that matter. Open rates, click rates, and revenue sit right next to subject lines so patterns surface fast.

“Build a dashboard showing my top 20 campaigns ranked by open rate, with subject line and revenue for each”

Connection needed: Connector only

Branded signup form

A signup form that matches your brand instead of a generic embed. Wire it to the right audience, attach the right tags, and watch a live subscriber count tick up underneath.

“Create a newsletter signup form that adds subscribers to my ‘Weekly Updates’ audience with the tag ‘website’ and shows total subscriber count”

Connection needed: Connector + API key

Engagement treemap

Your whole subscriber list, laid out by engagement level. Active subscribers in green, cooling off in amber, quiet in red. One look tells you the shape of your list.

“Show my subscriber list as a treemap colored by engagement: green for active, amber for cooling, red for inactive”

Connection needed: Connector only

Client reporting dashboard

A clean dashboard you can share with clients showing campaign performance without giving them access to your Mailchimp account.

“Create a client dashboard showing this month’s campaigns with opens, clicks, and unsubscribes in a branded layout”

Connection needed: Connector only

Connecting Mailchimp

Step 1: Connect the connector

You can connect from chat or from your project settings.

From chat:

“Connect my Mailchimp account”

From project settings: Open Settings, go to Connectors, and select Mailchimp.

When you start the connection:

1. Enter your server prefix. This is the region code in your Mailchimp URL. Log in to Mailchimp and look at the address bar. If your URL is us21.admin.mailchimp.com, your prefix is us21.
2. Click Connect Account.
3. Log in to Mailchimp when the authorization window opens.
4. Click Allow to authorize Sticklight.

Once connected, Sticklight can access your Mailchimp data while you build.

Step 2: Add your API key (when needed)

If you’re building something that collects submissions, like a signup form, Sticklight enables Cloud Backend automatically. This provides the backend function needed to securely send data to Mailchimp. Then it prompts you for your Mailchimp API key.

To find your API key:

1. In Mailchimp, go to Account & Billing → Extras → API keys
2. Create a new key or copy an existing one
3. Paste it into Sticklight when prompted

The key is stored securely and only used by your published app to send data to Mailchimp.

What visitors see

When you publish your app, anyone with the URL can view it. This includes any Mailchimp data you choose to display, like campaign performance, subscriber counts, or audience segments.

Before publishing, consider what information you’re sharing. A campaign leaderboard built for internal use shows different data than a client-facing report. You control what your app displays, so build with your audience in mind.

Limitations

• Account-level access. The connector accesses one Mailchimp account per connection. For multiple accounts, create separate projects.
• API rate limits. Mailchimp limits API requests. High-frequency updates may be throttled.
• Some actions require confirmation. Sending campaigns or deleting subscribers prompts for confirmation to prevent accidents.

FAQ

Does connecting Mailchimp cost anything?

No. Connecting is free and doesn’t use credits. You only spend credits when you build something.

Will this change anything in my Mailchimp account?

Your campaigns, lists, and automations stay exactly where they are. Dashboards you build read that data. Signup forms you build add new subscribers to the audience you choose. You stay in control of what connects to what.

What’s the difference between the connector and the API key?

The connector lets Sticklight read your Mailchimp data while you build. The API key lets your published app write to Mailchimp when visitors submit forms. Dashboards only need the connector. Signup forms need both.

Where do I find my server prefix?

Log in to Mailchimp and look at the URL in your browser. If you see us21.admin.mailchimp.com, your prefix is us21. It’s also the part after the dash in your API key.

Do I need to know how to code?

No. Describe what you want in plain language and Sticklight builds it. If you do write code, the files are there to open and edit.

How many tools can I build from one connection?

As many as you want. Connect once, then build a leaderboard, a form, an engagement view, or all three.

Can I share what I build with clients?

Yes. Publish to your project URL and send the link. Your dashboard, your brand.

Can I connect multiple Mailchimp accounts?

Each project connects to one Mailchimp account. For multiple accounts, create separate projects.
