Batch Email Validation/ Checking

Upload your email files

Our batch email verification service is ideal if you have an existing list of email addresses that you need to verify. It’s so simple, really!

1. Upload files, up to 100,000 emails at a time. Drag and drop files in. Formats supported are .txt and .csv files

Perform a pre-validation “clean-up” to remove known bad domains and invalid syntax before submitting to validation.

Your files can contain multiple columns of data.

2. Wait for the file to complete, then view the results

Download just the OK ones, the BAD ones or the Unknowns, or all results in one file.

See charts showing the percentages based on result and additional result information.
