What This Workflow Does

This automation solves the common marketing challenge of manually transferring new leads from HubSpot to Mailchimp for email campaigns. The workflow:

  • Checks HubSpot for new contacts at scheduled intervals
  • Maps relevant contact fields between systems
  • Adds subscribers to specified Mailchimp audiences
  • Maintains proper subscription status compliance

By automating this process, marketing teams ensure no leads fall through the cracks while saving 5-10 hours per week on manual data transfers.

How It Works

1. Scheduled Trigger

The workflow runs on a cron schedule (default: daily at 7 AM) to check for new HubSpot contacts added since the last run.

2. HubSpot Contact Retrieval

Queries HubSpot's contacts API to find recently created records, filtering by your specified criteria like contact property values or creation date.

3. Field Mapping & Transformation

Maps HubSpot contact properties to corresponding Mailchimp merge fields, with options to transform data formats if needed.

4. Mailchimp List Addition

Adds properly formatted contact data to your specified Mailchimp audience with "subscribed" status by default (configurable).

Frequently Asked Questions

Common questions about HubSpot and Mailchimp integration

Automating contact sync eliminates manual data entry errors, ensures timely list updates for campaigns, and saves marketing teams 5-10 hours weekly. The workflow maintains data consistency across platforms.

Manual transfers often lead to missed contacts during busy periods or formatting inconsistencies that affect segmentation and personalization.

You can map contact fields like email, first/last name, company, phone, custom properties, and tags. The workflow supports conditional logic to handle different contact segments.

Common mappings include: HubSpot lifecycle stage → Mailchimp tags, lead score → custom field, and custom properties for segmentation.

Most businesses sync daily or in real-time. This template uses cron scheduling - set intervals from minutes to months based on your campaign needs and contact volume.

High-volume operations may prefer hourly syncs, while niche B2B companies often find daily or weekly sufficient for their nurture sequences.

The workflow can be configured for both. By default it adds new contacts but can be extended to update existing records when source data changes in HubSpot.

For update functionality, you'd add a step to first check if the contact exists in Mailchimp before deciding whether to add or update.

Best practice is to sync unsubscribe status back to HubSpot. This template can be extended with a reverse sync to maintain compliance across both platforms.

Without this, you risk emailing unsubscribed contacts if they're still marked as marketing-contacts in HubSpot.

This offers more field mapping options, conditional logic, and scheduling flexibility than the native integration. It also avoids Mailchimp's contact duplication issues.

The native integration often requires workarounds for proper field mapping and can create duplicate contacts in Mailchimp when dealing with multiple HubSpot forms.
