_How to add and configure an Email field in the Notebook Editor._

---

## What This Field Does

An Email Field provides a single-line text input with built-in email format
validation. On mobile devices, it automatically opens the email keyboard
(with @ and .com keys). Use it for contact email addresses, researcher
emails, or notification addresses.

## Adding the Field

To add this field, open the
[ADD A FIELD dialog](../shared-settings/adding-a-field.md), navigate to the **TEXT**
tab, and click the **Email** card. Then click the **ADD FIELD** button in
the lower right.

## Configuring the Field

Click the field's **grey header bar** to expand it and see its settings.
For an overview of the settings shared by all fields — including Label,
Helper Text, Field ID, and the field toolbar — see
[Field Identity](../shared-settings/field-identity.md) and
[Field Toolbar](../shared-settings/field-toolbar.md).

Give the field a meaningful Label, review the auto-populated
Field ID, and add any desired Helper Text.

### Shared Field Options

Configure any of the shared field options as needed.

For settings shared across all field types — including Required,
Annotation, Uncertainty, Conditions, Copy value to new records,
and Display in child records — see
[Field Options](../shared-settings/field-options.md).

## Tips

- **The email keyboard on mobile** (with @ and .com keys) appears
  automatically — no extra configuration is needed.
- **Email format validation only checks structure** (user@domain.tld), not
  whether the address actually exists or is reachable.
- **For multiple contact emails,** add separate Email fields (e.g.,
  "Primary contact email", "Secondary contact email") rather than trying to
  enter multiple addresses in one field.
- **Enable Annotation** if collectors might need to note the role or context
  of the contact (e.g., "site manager", "weekend contact only").
