Connecting Mailchimp to Guest Wi-Fi Marketing using SocialSign.in Go

Overview

This guide walks you through connecting your Mailchimp account to SocialSign.in Go so that guest Wi-Fi sign-ins automatically sync to your Mailchimp audiences. Setup takes under 10 minutes.

What You'll Get

  • Guest Wi-Fi contacts synced directly into your Mailchimp audiences
  • Contacts added to the audiences you specify
  • Data to build targeted campaigns, automated journeys, and personalized communications for on-site visitors

What You'll Need

Step 1: Generate a Mailchimp API Key

  1. Sign in to your Mailchimp account
  2. Click your profile icon in the bottom-left corner, then select Account & billing
  3. Go to the Extras dropdown and select API keys
  4. Scroll to the Your API keys section and click Create A Key
  5. Give it a descriptive name (e.g., "SocialSign.in Wi-Fi") and copy the generated key

Important: The API key is only shown once when created. Copy it immediately and store it securely.

Step 2: Configure the Integration in SocialSign.in

  1. Sign in to your SocialSign.in client app
  2. Navigate to Integrations → Mailchimp
  3. Paste your Mailchimp API key into the API Key field
  4. Select the SocialSign.in locations you'd like to connect
  5. Choose which Mailchimp audience each location should sync contacts to
  6. Click Save

Step 3: Verify

After a guest connects to your Wi-Fi and completes the sign-in, confirm that new contacts are appearing in your Mailchimp audience.

Optional Settings

  • Update existing contacts: Choose whether to update existing Mailchimp contacts when a returning guest signs in
  • Tags: Automatically tag contacts synced from Wi-Fi for easy segmentation

Troubleshooting

Contacts not appearing in Mailchimp?

  1. Verify your API key is correct — go to Account & billing → Extras → API keys in Mailchimp to confirm it's active
  2. Make sure the API key hasn't been disabled or regenerated since you entered it
  3. Confirm your SocialSign.in locations are selected on the integration settings page
  4. Confirm a Mailchimp audience is selected for each location
  5. Check that the guest's email isn't already unsubscribed or cleaned in your Mailchimp audience (Mailchimp won't re-add unsubscribed contacts)
  6. Still stuck? Contact us at support@socialsign.in

What Happens Next?

Every guest who connects to your Wi-Fi and opts in will automatically be added to your chosen Mailchimp audience. Use Mailchimp's campaign builder, automations, and segmentation tools to engage these contacts — welcome series, location-based campaigns, re-engagement flows, and more.
