Case Study

Migrating 84 Email Lists Into a Unified HubSpot Database

Challenge

The needed to consolidate and migrate a large volume of contact data from Klaviyo into HubSpot. The organization maintained 84 separate CSV files containing contact records, all of which needed to be imported, mapped correctly, and organized within HubSpot while preserving the integrity of the data.

The challenge extended beyond a simple import. The team needed to ensure that contact properties were mapped consistently across all files, lists were structured appropriately in HubSpot, and future marketing activities could be supported by a clean, centralized database. With thousands of records spread across dozens of files, manual imports would have been time-consuming and prone to errors.

Solution

No Bounds Digital partnered with Combat Antisemitism Movement to design and execute a structured data migration strategy. After reviewing the organization’s requirements, our team identified that all 84 CSV files followed a consistent format, enabling a scalable migration process.

The project included:

  • Auditing the source data exported from Klaviyo.
  • Mapping contact properties to the appropriate HubSpot fields.
  • Importing and organizing 84 CSV files into HubSpot.
  • Creating the necessary lists and segmentation structure within HubSpot.
  • Validating imported records to ensure accuracy and completeness.
  • Providing HubSpot administration guidance to support ongoing marketing operations.

Following the initial migration project, No Bounds Digital continued supporting the organization with HubSpot administration, marketing automation planning, reporting, and paid advertising strategy discussions as the relationship evolved.

Results

The migration project provided Combat Antisemitism Movement with a centralized, organized marketing database that could be used to support future fundraising, advocacy, and engagement initiatives.

Key outcomes included:

  • Successful migration of 84 CSV files into HubSpot.
  • Consolidation of previously segmented contact data into a single CRM platform.
  • Standardized contact property mapping across all imported records.
  • Improved data accessibility for marketing and outreach teams.
  • Established foundation for future marketing automation, lead nurturing, reporting, and campaign management initiatives.

While specific contact counts were not documented, the project eliminated the complexity of managing dozens of disconnected spreadsheets and created a scalable HubSpot environment capable of supporting the organization's continued growth.
