# Split e-mail addresses[¶](https://doc.dataiku.com/dss/latest/preparation/processors/email-split.html#split-e-mail-addresses "Permalink to this headline")

This processor splits an e-mail address into the local part (before the @) and the domain (after the @).

The output values are produced in columns prefixed by the input column name.

If the input does not contain a valid email address, no output value is produced.
