Hey there Gabriel thanks for reaching out, that is correct if the "safe to Send" option is turned on Catch All emails will not appear in your results. Currently we do not have the AI scoring system of Zerobounce as part of the result in Clay. If you would like to use it you will need to use an HTTP API connection to connect with Zerobounce directly to make use of its scoring system.
The following link contains documentation and videos on how to use the HTTP API in Clay.
