Bulk import contacts to the tester group

The bulk import API is not designed to sync updates in real-time from an external database.

Skipped contacts

Contacts must meet all the following criteria in order to be created or updated with this API:

• The imported contacts may not exceed your account limit.
• The contact must have a valid email address.
• The contact's email address must not be on an exclusion list.
• The contact's email must not be on a list of bounced email addresses.

If contacts do not meet all of these requirements, they will be skipped by the importer.
