Bulk Validation Preview

Note:

Bulk validation preview performs a free analysis of a list of email addresses allowing you to make an informed decision to run a complete bulk validation or not. Given a preview name and an uploaded file of email addresses, a preliminary validation run will be preformed. The results of the preview will be, on average, an estimate of the deliverability and risk of the emails provide. This evaluation is based on a statistical sampling of the list provided.

Note:

It's important to upload as multi-part/form-data where the file is defined by file. Currently only raw csv and gzip are supported. While there is no limit on the number of email addresses that can be provided, the file size cannot exceed 25MB. The column header for emails needs to be either email or email\address_

Warning!

Lists must comply to either UTF-8 or ASCII encoding and not have a '@' in the name.
