Is my data safe?

We are committed to providing maximum security for your data and understand its seriousness.

TheChecker complies with GDPR: General Data Protection Regulation (EU) 2016/679 and thus for the purpose of identifying whether an email address exists, the verification happens in an online, fully automated system.

To this end, any files that you upload on the system (in bulk verification), gets automatically deleted after 30 days. Please read about our Privacy Policy here:

This means that you are not able to access any files that you uploaded in your bulk verification after 30 days, so remember to download them in that timeframe. Any data entered in the ‘Single Verification’ system is always accessible.

Do I need to have a specific file format?

We are glad to say that we accept a wide file type compatibility. You can upload a CSV, TXT, XLS or XLSX file, with or without a header and with any amount of columns. This means that if you have other information in the file, it can still be uploaded and validated.

Please remember that: you must have all the emails in the same column and only 1 (one) email per row.
