Select the contacts you want to update.
If you're updating the list to prepare for the upcoming GDPR related changes, you can find a list with invalid country entries on the Interests page, in a group called "Envoke Support". The interest is called "Invalid country values".
If this interest doesn't exist it means all contacts in your account have a valid country code. There may still be contacts with a blank country field but blanks aren't considered invalid. In case of a missing country field the "default country" setting is used.
Update the values in the country column in the exported list to use a supported ISO country code or country name.
Remove unrelated columns from the file - leave only email and country.
Re-import the list using the following settings:
- no need to add a new interest/list
- use a source "Existing contacts"
- set consent to "not provided" -- because you're re-import existing records their consent status will NOT change. If contacts already provided express or implied consent this will NOT be removed. The original consent status will be kept.
