Display conditions let you show or hide a whole row of your email based on a subscriber's attributes - location, interests, age, anything you store about them. It's the visual, no-code way to personalise (for the HTML-based approach, see **[Use dynamic content](/knowledgebase/mailmachine-campaigns/use-dynamic-content)**). This guide covers setting one up.

## Set a display condition

1. Make sure the attribute you want to use exists on your list - see **[Add attributes to your list](/knowledgebase/contacts-audiences/add-attributes-to-your-list)**.
2. Open the email you want to edit.
3. In the email designer, go to the **Rows** section.
4. Drag a row into the email and select it.
5. In the row's properties, select **Add Condition**.
6. Configure the condition - which attribute, and what it must match.
7. Click **Confirm**.
8. Preview with the eye icon, choosing different attribute values from the dropdown to see how each subscriber's version looks.

The condition then shows in the row's properties for easy editing.

## Where it's useful

- **Location** - region-specific offers, local events, timezone-aware content.
- **Demographics** - age-appropriate recommendations, interest-based blocks.
- **Behaviour** - content keyed to purchase history or engagement level.

## Best practices

- **Start simple** - one attribute like location or interest.
- **Always provide a fallback** - default content for subscribers who lack the attribute, so nobody sees a blank.
- **Test thoroughly** - preview across different attribute values, including empty ones.
- **Keep it relevant** - only condition on things that genuinely improve the email.

## Troubleshooting

**Conditions don't work as expected** - check the subscribers actually have data for that attribute, and that the values match your criteria exactly. Test with a few different profiles.

**Content shows for the wrong people** - review your AND/OR logic and check for conflicting conditions and data-type mismatches.

**Subscribers see blank sections** - always include fallback content; the gap means some contacts lack the attribute.

**Performance issues** - limit the number of conditions per campaign and avoid deep nesting; for very different audiences, separate campaigns can be simpler.
