SecureEvery 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 TypesSuppressionList can store any type of data that you want to match against - phone numbers, email addresses, zip codes, sales regions and more.
Automatic List PruningYou 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.
Timestamped RecordsWhen 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.
Lightning Fast APIThe SuppressionList API allows you to query and append to one or more lists and receive a response in milliseconds, even if your lists are comprised of millions of records.
Atomic List UpdatesYou can wholesale replace an entire list using a file upload, even if that list is being actively queried. SuppressionList won't skip a beat. It'll seamlessly swap out the old list for the new one. This is useful for people whose have a list that is provided by a third party on a periodic basis.
Pay for What You Use
The number of times SuppressionList is queried plus the number of records stored across all of your lists. We do not charge per list, nor for the number of query URLs you give to your providers, though the queries that the generate on those URLs are included in your cost. Learn more.
