Both determines if an expression has a value and returns TRUE if it does not. If it contains a value. this function returns FALSE.
- ISBLANK(expression) : The expression allows both number and text fields
- ISNULL(expression): Here the expression allows only number fields.
- [adinserter block='9']

ISBLANK() has the same functionality as ISNULL(), but also supports text fields. Salesforce will continue to support ISNULL, so you do not need to change any existing formulas. ISNULL(): Text fields are never null, so using ISNULL() with a text field always returns false.
