Skip Trace - this action searches in multiple databases to collect all possible contact information for leads/properties, including phone numbers and email addresses.
DNC Scrub - compares the phone numbers to the National Do Not Call Registry to see if the contact has proactively stated they do not want to be contacted with offers.
Note: using Skip Tracing and DNC Scrubbing will incur per-lead usage charges.
If you are not sure if you want to Skip Trace or DNC Scrub while importing, you can later opt to using the "Actions" button from within the Source.
