Prospects

Import prospects from a CSV file

You can import up to 50,000 prospects at a time from a CSV file — exported from a spreadsheet, a CRM or a lead database.

Prepare the file

  • One prospect per row, with a header row naming the columns.
  • An email column is required. Everything else is optional.
  • Save as CSV (UTF-8) from Excel, Google Sheets or Numbers.

Import

  1. Go to Prospects and click Import.
  2. File: drop in your CSV.
  3. Map columns: match each column to an Outsquid field — Email, First Name, Last Name, Company, Job Title, Phone, LinkedIn URL, Website, City, State, Country or Timezone. Choose Custom field to keep any other column (you can use it as a variable in your emails), or Skip this column to leave it out.
  4. Review & Import: check the preview, optionally add everyone to a list, and choose what to do with duplicates.

Duplicates

If an email address is already in your prospects, choose:

OptionWhat happens
SkipThe existing prospect is left as it is
Fill empty fieldsOnly fields the prospect is missing are filled in
OverwriteFields are replaced with the values from the file

Empty cells never erase a value, and a prospect's status is never changed by an import.

Skipped rows

Rows without a valid email address are skipped, and so are addresses on your blacklist. The import summary tells you how many were added, updated and skipped.

Timezones

Use names like America/New_York or Europe/London. Values Outsquid doesn't recognise are left empty rather than guessed.
