Integrate Mailchimp with Zoho CRM using SyncApps

Saving time and reducing data errors in marketing and CRM workflows is the most frequently asked question during SyncApps demos with our trial users.

One of our first integrations, launched in 2009 on SnapLogic, connected Zoho CRM and Mailchimp. It was a game-changer, addressing the major issue of disconnected, popular business software.

Our subscriber base for this integration grew rapidly from 2009 until around 2012, when Zoho CRM introduced Zoho Campaigns, a direct Mailchimp competitor. By 2015, most of our Zoho CRM and Mailchimp SyncApps users required complex, bidirectional integrations that Zoho Campaigns couldn’t offer, such as those utilizing Zoho CRM’s Custom Modules.

We also began to see agencies using Zoho CRM for their clients, often in conjunction with Mailchimp or Act-On, as Zoho Campaigns wasn’t robust enough for their clients’ eCommerce platforms.

Today, although SyncApps primarily serves Salesforce and NetSuite, we continue to offer robust Zoho CRM integrations with Mailchimp, Act-On, and Constant Contact, which consistently attract new subscribers.

So today let’s tackle how to set up Mailchimp with Zoho CRM using SyncApps to help you sync customer data automatically, improve campaign targeting, and streamline sales and marketing efforts. Here’s what you’ll get:

• Automated Data Sync: Sync customer data every 2 minutes to keep records accurate and consistent.
• Improved Marketing Efficiency: Segment Zoho CRM contacts or leads into Mailchimp Audiences, Groups, or Tags for precise targeting.
• Sales Insights: Access marketing engagement data directly in Zoho CRM to make smarter decisions.
• Time Savings: Eliminate manual data entry and focus on strategic tasks.

Quick Overview of Setup:

1. Generate a Mailchimp API key and configure your audience list.
2. Prepare Zoho CRM with admin permissions, clean data, and standardized fields.
3. Create a SyncApps account, connect both platforms, and map fields for seamless synchronization.

This integration bridges the gap between marketing and CRM, enabling better collaboration and stronger customer engagement.

Setup Requirements and Checklist

Before diving into the integration process, make sure your systems are correctly configured to ensure smooth synchronization between Mailchimp and Zoho CRM.

Mailchimp Setup Steps

Follow these steps to prepare Mailchimp for integration:

• API Key Generation
  Head to Account Settings > Extras > API keys to generate a new API key. Assign it Manager permissions, label it specifically for SyncApps integration, and store it securely for future use ^{[pro tip]}.
• Audience Configuration
  Double-check that your primary Mailchimp audience list meets these standards:
  • All contacts have valid email addresses ^[4].
  • Custom fields are well-structured.
  • Data formats are clean and standardized.

Zoho CRM Setup Steps

Setup Component	Required Configuration
User Access	Assign admin-level permissions.

These adjustments will ensure Zoho CRM is ready for integration.

SyncApps Initial Setup

Once Mailchimp and Zoho CRM are configured, set up your SyncApps account:

• Account Creation

• Integration Essentials
  Gather the following for a smooth setup:
  • Mailchimp API key with Manager permissions.
  • Zoho CRM admin credentials.
  • Identifier for your primary Mailchimp audience list.
• Authentication Setup

Keep in mind: during synchronization, Zoho CRM data takes priority unless you’re using a Mailchimp update profile form ^[Webhooks].

With these preparations complete, you can move on to the integration process.

Integration Setup Guide

Now that your systems are ready, let’s go step by step to connect Mailchimp with Zoho CRM using SyncApps.

Setting Up Your Sync Profile

Here’s how to create your integration profile in SyncApps:

• Access Setup Area
  Head to the “Set-Ups” tab in your SyncApps dashboard and click on “Create Set Up.” Give your setup a clear and descriptive name, like Zoho-Mailchimp-Primary, so it’s easy to identify later.
• Configure Integration Type
  Choose “Zoho CRM to Mailchimp” as your Sync Type. This sets the primary direction for data flow. If needed, you can adjust this later to enable two-way synchronization in Field Mapping area.
• Select Sync Options
  Decide which Zoho CRM modules to integrate based on your needs: Contacts or Leads, or even Accounts

Once your profile is set up, you’re ready to connect your accounts.

Connecting Your Accounts

• Zoho CRM Authorization
  Click “Authorize Zoho CRM” and follow the OAuth2 process to securely grant access.
• Mailchimp Connection
  Enter your Mailchimp API key and choose your primary audience list. Make sure your Mailchimp account has Admin-level permissions. As always, it’s super easy to set it up. It takes less than 10 minutes. Seriously, we’ve timed it.

With both accounts authorized, you can now move on to mapping your data fields.

Field Mapping and Data Sync

This is where you configure how information flows between Zoho CRM and Mailchimp.

• Standard Fields
  Basic fields like Email Address, Name, and Opt-Out status are pre-mapped for your convenience ^{[Integration Guide]}. Double-check these defaults to ensure they fit your specific requirements.
• Custom Field Configuration
  For specialized data, map custom fields between the two platforms: Zoho CRM Field Mailchimp Field Purpose Industry Tags Automatically categorize contacts Lead Source Custom Field Track where leads come from Account Type Groups Segment subscribers effectively
• Data Rules Setup
  Fine-tune how data is handled during synchronization:
  • Use “Unknown” as a placeholder for blank last name fields to maintain consistency.
  • Enable deletion synchronization to keep your lists up to date.
  • Set up field expression mapping for more complex data transformations.

Advanced Integration Tools

Once your setup is in place, these tools can help fine-tune your integration for better efficiency and control.

List Management and Tags

SyncApps simplifies how you organize and manage data with its list management and tagging features. It allows you to seamlessly segment Zoho CRM records into Mailchimp Audiences, Groups, or Tags.

Here’s how segmentation works:

Segmentation Type	Purpose	Example Criteria
Filtering	Control data flow	Active customers with purchases > $5,000
Groups	Categorize contacts	Industry-specific newsletters
Tags	Dynamic labeling	Lead source tracking

Idea: Try DryMerge, so you don’t have to worry about inconsistencies. It automatically updates your Zoho CRM by constantly monitoring your email, calendar, and calls to keep your CRM updated with every detail. This will save you from manual updates and avoiding mismatched data when using SyncApps.

Two-Way Updates Management

SyncApps prioritizes Zoho CRM as the primary source of truth, meaning any updates in Zoho CRM automatically sync to Mailchimp. However, updates from Mailchimp to Zoho CRM only happen in two specific cases:

• When an email address is not already present in Zoho CRM.
• When updates are made via the Mailchimp Update Profile Form, provided the fields are correctly mapped.

This ensures your data remains accurate and aligned across both platforms. Unsubscribe data is synced from Mailchimp unless you choose not to in every integration.

Sync Timing Options

Choose a sync schedule that fits your business needs:

Plan	Sync Interval	Records/Month	Annual Cost
One Plan	Real time	Unlimited	$1,800 (20% off for yearly)
Free	Every 24 hours	100	Free

You can adjust the sync timing in your account settings, and the system will follow your account’s timezone. For testing new configurations, the “Sync on Demand” feature is a handy tool. It lets you verify your integration settings before activating automated schedules, ensuring data flows as expected.

Now that you’ve explored these advanced tools, the next section will guide you through troubleshooting and optimizing performance.

Problem-Solving and Performance

To keep the integration between Mailchimp and Zoho CRM running smoothly, it’s crucial to address common issues proactively and ensure everything operates at peak efficiency. Regular monitoring and attention to detail can make all the difference.

Fix Common Integration Issues

One of the biggest hurdles in syncing Mailchimp with Zoho CRM is dealing with data mismatches. Here’s a quick breakdown of common problems and how to tackle them:

Issue Type	Common Symptoms	Solution
Field Mapping	Inconsistent or missing data	Double-check field names and formats in both systems.
Duplicate Records	Multiple entries for the same contact	Set up merge rules based on email addresses.
Sync Delays	Outdated information across platforms	Enable real-time webhooks for key updates.

When synchronization fails, always check API permissions in both systems. Research shows that 44% of businesses lose over 10% of their annual revenue due to inaccurate CRM data.

Speed and Efficiency Tips

Want to get the most out of your integration? These tips can help:

• Match field formats: Use field validation in Zoho CRM to align with Mailchimp’s requirements.
• Schedule syncs wisely: Run resource-heavy syncs during off-peak hours to avoid slowing down operations.
• Filter smartly: Apply filters to sync only the most relevant data, cutting down on processing time.

For critical updates, enable real-time webhooks. This ensures essential information is synced immediately without bogging down the system.
