How does Is Empty and Is not Empty filter type works?

Is Empty filter type

The Is Empty filter checks whether a field has no value at all.

It’s like asking: “Is this field completely blank?”

Example:

You're filtering a list of users by their email:

Apply:

• Filter: Email Is Empty

Matches:

• • User 002 ✅

  • User 003 ✅

  • User 001 ❌

This is especially helpful when:

• Finding users with missing profile information (like no phone number, no address)

• Identifying records that need data enrichment

• Excluding incomplete entries before sending campaigns

• Spotting blank form submissions

Is not Empty filter type

The Is not Empty filter checks whether a field has value at all.

It’s like asking: “Is this field completely blank?”

Example:

You're filtering a list of users by their email:

Apply:

• Filter: Email Is not Empty

Matches:

• User 001 ✅

• User 002 ❌

• User 003 ❌

This is especially helpful when:

• Filtering for records with complete information

• Ensuring you only message users who have an email or phone number

• Creating segments based on filled-in data fields (e.g., birthday, country, product preference)

Available for field types: Text, Number, Date, Boolean, EmailAddress, Phone, Decimal, Locale
