Conditional logic forms: ask only the right questions.
With conditional logic, a question appears only if it concerns the respondent and a page can skip another one: your forms and surveys stay short, and everyone sees only what matters to them.

A form that adapts to each respondent
An individual has no VAT number, a happy customer doesn’t need to explain what disappointed them. With the conditional logic of the form builder, you say when a question should appear, and the form rebuilds itself live as answers are given. Fewer unnecessary questions means fewer drop-offs and more accurate answers. Conditions work the same way in all your Mailpro forms and in your online surveys.
The conditions available
| Compare | equals, does not equal, is one of |
| Text | contains, does not contain, is empty, is not empty |
| Number and rating | greater than, less than, or equal |
| Checkbox | is checked |
| Combine | all conditions (and), any of them (or), and groups within groups |
| Apply to | a question, a whole row, or the move from one page to the next |
A question at the right moment
Show “Please specify” after “Other”, the delivery address when the box is checked, or “Why?” when the rating is low. A condition can apply to a single question or to a whole row of fields. For examples and best practices, read our guide to survey branching.
A path based on the answers
In a multi-page form, decide where the respondent goes after each page: to the page that concerns them, or straight to submission. A default page covers every other case. This is what’s known as branching logic; our FAQ explains how to set up branching in a survey.
Clean answers
Conditions are checked again on our servers on submission: a hidden question is never stored, and a required question only counts as required when it is shown. Your exports and form statistics contain only answers that make sense.
