The file creation endpoint allows you to verify multiple emails at once by creating a task to process the file asynchronously. Verification results are not included in the response.

File upload recommendation

Your file_url must be public – ensure that the source you provide is accessible to everyone. For efficiency and deduplication, submit data in a single task rather than splitting it. For example, submit one file with 50k emails instead of 10 files of 5k each. If using data from a CRM, buffer it locally before submission.

Size limiting

The Bulk API supports files up to 65 MB.
