    Every item added to SuppressionList is MD5 hashed before it is added. Nothing is stored in the clear. Plain text queries are hashed, so you don’t need to worry about hashing it yourself.
  • Flexible Data Types

    SuppressionList can store any type of data that you want to match against - phone numbers, email addresses, zip codes, sales regions and more.
  • Automatic List Pruning

    You can set an automatic expiry period on each of your lists. SuppressionList will automatically delete records once they are older than the timeframe you’ve set, keeping your lists clean.

    When SuppressionList finds a matching record, it will include the date and time that record was added to the list, so you can make decisions based on the age of the initial entry. This makes it easy to keep a comprehensive list of leads without sacrificing flexibility to meet different business requirements.
