SEND FILE CODE SAMPLES
Have you activated our email validationⓘ API and would like to send your file?
The sendfile API allows you to send a file for bulk email validationⓘ. The content type needs to be multipart/form-data. Please refer to the C# example for details.
There is no restriction on file size, number of emails, or number of files you can submit using this endpoint. As long as you have the credits in your account to cover the number of emails submitted in the file, your file will be accepted.
Consider activating AutoPay in your ZeroBounce account and ensure you never run out of credits.
