Customers and data

Upload and use your own customer list

Bring contacts you already own, and keep them separate.

You can upload contacts you already have — existing customers, past enquiries, event attendees — and run campaigns against them alongside your platform campaigns.

Preparing the file

  • An .xlsx or .csv file with a header row.
  • An email column is required. Everything else is optional.
  • Name can be one column or First name and Last name.
  • Common header spellings are recognised automatically, and you can correct the mapping before importing.

How it stays separate

  • Your contacts are stored in your own tables, kept separate from the platform’s own data.
  • They are never eligible for platform customer selection, for you or anyone else.
  • Own-list campaigns do not consume your daily platform allocation.
  • You can delete the list at any time.

Your list, your responsibility

You must have a lawful basis for emailing everyone on it. Unsubscribes, suppression and your provider’s sending limits all still apply.
