The validTo Bulk Validation API offers to verify multiple email addresses in a single API request. You are able to create a new bulk email validation list in CSV format. The size of the file should be up-to 10Mb. You can initiate verification of your created list . The progress and current status of the bulk validation list can also be fetched using this API. You can also get the analysis and result status of the bulk validation list. Once the verification of the list gets ‘completed’, you can download the result. You can also delete the created bulk validation list if needed.
You can also test API endpoints easily in our API reference.
