Export guide · Gmail or Outlook contacts

Export a contacts group, not the whole address book.

A mailbox export holds suppliers, staff, applicants and friends alongside customers. Filter to a group or label first, so the file holds only people who dealt with your business.

Export it

  1. Make a group or label for customers first

    In Google Contacts, add a label such as Customers to the people who enquired or bought. In Outlook, put them in a contact list. Everyone else stays out of the export.

  2. Google Contacts: Export, choose the label, Google CSV

    Open contacts.google.com, choose Export, pick the label you made, and choose Google CSV.

  3. Outlook: People, Manage, Export contacts

    Choose the contact list you made and export as CSV.

  4. Delete the columns you do not need

    A mailbox export has dozens of columns. Keep email, name and any notes-free date you have. Delete the rest before uploading.

  5. Upload that file

    Create your private Desk and upload the CSV.

Which columns to keep

Only the email is required. Everything else is optional, and less is safer.

Keep

  • Email (required)
  • Name
  • Group or label name, if it says what the relationship was

Delete before upload

  • Phone numbers you do not need
  • Postal addresses
  • Notes
  • Birthdays and personal dates
  • Anyone who is staff, a supplier, an applicant or a personal contact

A mailbox export rarely says what the relationship was. Records without relationship evidence are shown as "relationship evidence missing" and held. That is expected, not an error.

Before you upload

  • Run the checklist. Two minutes, and it is the part that protects the people in your list. Open the checklist
  • Try a template first. A synthetic file with every state in it, so you know what you will see. Templates
  • Stuck at any step? Ask for help without sending a single row. Assisted help

Conclusions cover only the file you upload and the suppression sources you declare. Anything not in them is not checked.
