Common and frequent questions

How fast is list cleaning?

Seconds to minutes.

Thanks to our latest generation platform and infrastructure, we are able to do dozens of checks per second per email at a planetary scale.

Whether the list is 100 or 100,000,000, we have the technology and limitless infrastructure to process practically each entry in parallel and simultaneously.

Is my data secure?

Absolutely. We use better-than-bank security protocols and technologies.

All data on disk, including your email lists, are encrypted with 256-bit Rijndael encryption with secure keys. All identifiers are 128-bit numbers which are impossible to reverse engineer or collide. All communication and transfers are done over a secure 256-bit Secure Sockets Layer encrypted connection.

What other costs are there?


The only charge is after you click "clean list", which will first confirm the amount and your acceptance. Everything else you do in the platform is free.
