"Contains" Filter

The "Contains" field filter

Lead Prosper can use the power of regular expression to filter your leads and ensure only the highest quality leads are sent to your buyers, per their requirements. Please note that this is an advanced feature.

The "Contains" field filter can be used in the following field types:

  • email
  • postal code
  • phone
  • URL and domain
  • IP address
  • text

Here are a few examples on how to use them:

  1. to block any email that contains test@ or ends with "example" domains, you will use the following 2 entries
    • test@
    • @example.*$
  2. to block zip codes or phone numbers that starts with 123, you will use ^123
  3. to block zip codes or phone numbers that end with 333, you will use 333$
  4. to block multiple IPs from one subnet range, you will use 192.168.* - you can also pass here individual IPs, as in 127.0.0.1
  5. in a multi-word text field, there are a few cases that you might need
    • if you use random - this will match any word that contains random, such as randomizer or nonrandom
    • if you use \btest - this will match only words that start with the word test, such as testing, but will not match contest
    • if you use apple\b - this will match only words that end with the word apple, such as apple or pineapple, but not applesauce
    • if you use \bexact\b - this will only match the word exact
