The **Email Field** is one of the most important elements in a form. It helps you collect valid email addresses from your respondents and also allows advanced controls to prevent spam, ensure accuracy, and enable secure verification.

### Adding the Email Field
* Open your form in the editor from the Formester dashboard.
* Click **Add Elements**.
* Under **Contact Fields**, choose **Email**.
* The email field will appear on your form with a default placeholder text (like “Enter your email”).

### Basic Settings
* **Label**: Change the field label to something clear, such as “Your Email Address.”
* **Placeholder**: Add hint text like “[example@email.com]()” to guide users.
* **Required Toggle**: Make the field mandatory if you want every respondent to provide an email.

### Advanced Settings
###### Default Value
* Pre-fill the field with a set email if needed.
* Example: Use your company’s internal testing email while testing forms.

###### Make Unique
* Toggle on **Unique Email** to restrict each respondent to submit only once with a given email.
* Useful for event registrations, limited offers, or survey submissions where duplicates are not allowed.

###### Email Confirmation
* Enable [**Email OTP Verification**](https://formester.com/features/email-verification/) to send a one-time passcode to the provided email.
* Respondents must enter the code before submission is accepted.
* Ideal for secure registrations, gated content, or forms that need verified email lists.

### When to Use the Email Field
* Collect contact details for newsletters or updates.
* Register participants for events or webinars.
* Verify identities before granting access to gated resources.
* Run secure surveys where each person should respond only once.

### Publishing Your Form
* Once your email field is set up and customized, click **Publish**.
* Preview the form to ensure validation, uniqueness, and verification work as expected.
