Is not one of passes when the field matches no entry in a comma-separated list. It is the inverse of Is one of, and the natural way to write a blocklist.

When to use it

Use it to keep known-unwanted records out of a destination platform. Internal test submissions, staff email addresses, and spam-heavy lead sources are the common cases.

How to configure it

  1. Open AFI → Integrations and edit your integration.
  2. Switch on Conditional Logic.
  3. Pick the field, choose Is not one of, and list the values to exclude, separated by commas.

How it behaves

Entries are trimmed and compared without regard to case. TE**@*****le.com matches an entry of te**@*****le.com.

An empty list passes. With nothing to exclude, every submission satisfies the rule, which keeps the integration running rather than silently blocking it.

Example

Your team submits the contact form during QA. You want those runs kept out of the CRM.

Set the rule to {{email}} Is not one of **@*********ny.com, te**@*********ny.com. Real enquiries continue through, and QA runs stop.

Notes

Exact matching against a whole field is what this operator does. To exclude everything from a domain rather than named addresses, use Does not contain with @yourcompany.com.
