How can I speed up large list imports?

If you’re importing very large lists, the process can take some time. To improve performance, we recommend using a Last Modified Date filter on your Salesforce source report (or list view) with a relative date such as Last 2 Days. This way, the filter adjusts automatically and only pulls in records that have changed recently.

Key tips:

• First import: Do not apply the date filter the first time you run the import, so all records are brought in initially.

• Ongoing imports: After the first run, add the Last Modified Date filter. This ensures only recently updated records are imported, instead of reprocessing the entire list each time.

• Single-object reports: This method works best when the import maps fields from a single object (e.g., Contacts or Leads). If your report spans multiple objects, you would need to check each object for modifications, which may limit the benefit.

• Small lists: If your list is relatively small, you can skip this step. The hourly imports won’t take long enough to matter.
