How to Add Email Fields to WordPress Forms

Email is the lifeline of online communication. Every contact form, newsletter signup, and registration needs a reliable email field. But a basic text input isn’t enough—you need validation to catch typos, optional confirmation to ensure accuracy, and proper formatting for usable data. Here’s how to add email fields that work.

Why Use a Dedicated Email Field?

Problems with Text Fields for Email

• No format validation
• Typos go undetected
• Invalid entries accepted
• No email keyboard on mobile
• Wasted follow-up attempts

Benefits of Email Fields

• Built-in format validation
• Catches common errors
• Email keyboard on mobile devices
• Standardized data collection
• Better deliverability for follow-ups

Adding an Email Field

Step 1: Add the Field

1. Open your form in AFB
2. Find Email in field types
3. Drag to your form

Step 2: Configure Basic Settings

• Label: “Email Address” or “Your Email”
• Placeholder: “[email protected]”
• Required: Usually yes for contact forms
• Help text: Optional instructions

Step 3: Save and Test

1. Save your form
2. Preview on frontend
3. Try submitting invalid email
4. Verify validation works

Email Validation

What Gets Validated

Email fields check for proper format:

Valid:
✓ [email protected]
✓ [email protected]
✓ [email protected]

Invalid:
✗ userexample.com (missing @)
✗ [email protected] (missing domain)
✗ user@example (missing TLD)
✗ @example.com (missing username)

Validation Error Messages

Default: "Please enter a valid email address"
Custom: "That doesn't look like an email. Please check and try again"

What Validation Doesn’t Check

• Whether email actually exists
• Whether mailbox is active
• Deliverability

Format validation ensures proper structure, not existence.

Email Confirmation Field

What Is It?

A second email field where users re-enter their address. Both must match to submit.

Email: [[email protected]    ]
Confirm Email: [[email protected]    ] ✓ Matches

Why Use Confirmation?

• Catches typos (most common: wrong domain)
• Forces users to double-check
• Reduces failed email communications
• Critical for important transactions

When to Use

• Account registration
• Newsletter signups
• Order confirmations
• Any form where email accuracy is critical

When to Skip

• Simple contact forms
• Quick inquiries
• When reducing friction is priority

Enabling Confirmation

1. Select your email field
2. Find “Confirmation field” option
3. Toggle ON
4. Second field appears automatically

Confirmation Behavior

Email: [email protected]
Confirm: [email protected]  ← Typo!
Error: "Email addresses do not match"

Domain Restrictions

What Are Domain Restrictions?

Limit which email domains are accepted:

• Whitelist: Only allow specific domains
• Blacklist: Block specific domains

Whitelist Use Cases

Only accept emails from certain domains:

Allowed: @company.com, @company.org
Rejected: Everything else

Use for:
- Internal company forms
- Employee registration
- Organization-only access

Blacklist Use Cases

Block certain domains:

Blocked: @mailinator.com, @tempmail.com, @guerrillamail.com
Allowed: Everything else

Use for:
- Preventing disposable emails
- Reducing spam signups
- Ensuring real contact addresses

Configuring Domain Restrictions

1. Select email field
2. Find domain restriction settings
3. Choose whitelist or blacklist mode
4. Enter domains (one per line)

Example: Company Emails Only

Mode: Whitelist

Domains:
mailinator.com
tempmail.com

Mobile Optimization

Email Keyboard

Email fields trigger specialized mobile keyboard:

• @ symbol easily accessible
• .com shortcut on many keyboards
• Reduced autocorrect interference
• Faster entry

Mobile Best Practices

• Clear, readable label
• Helpful placeholder text
• Adequate tap target size
• Clear error messages

Common Email Field Mistakes

1. Using Text Instead of Email Type

Wrong: <input type="text">
Right: <input type="email">

Email type enables validation and mobile keyboard.

2. Not Making Required When Needed

If you need to reply, email should be required.

3. Confusing Placeholder for Label

Wrong: Placeholder only, no label
Right: Clear label + helpful placeholder

4. Overly Strict Validation

Some valid emails look unusual:

Valid but uncommon:
- [email protected]
- [email protected]
- [email protected]

Don’t reject valid formats.

5. No Error Message Context

Bad: "Invalid input"
Good: "Please enter a valid email address (example: [email protected])"

Email Field Labels

Good Label Examples

• “Email Address”
• “Your Email”
• “Email”
• “Work Email”
• “Contact Email”

Context-Specific Labels

• “Email (for order confirmation)”
• “Email (where we’ll send your download)”
• “Company Email”
• “Preferred Email”

Placeholder Examples

• “[email protected]”
• “Enter your email address…”
• “[email protected]”
• “[email protected]”

Help Text Ideas

Privacy Assurance

"We'll never share your email with anyone"
"Your email is kept confidential"
"We respect your privacy"

Usage Explanation

"We'll send your confirmation here"
"Where should we send the download link?"
"You'll receive updates at this address"

Format Guidance

"Use a valid email format (example: [email protected])"
"Please use an email you check regularly"
"Enter the email associated with your account"

Multiple Email Fields

When to Use Multiple

• Primary and secondary contact
• Personal and work email
• Billing and shipping notifications

Example: Primary/Secondary

Primary Email: [________________] (required)
Secondary Email: [________________] (optional)
Help text: "Secondary email for backup contact"

Example: Account + Notifications

Account Email: [________________]
Notification Email: [________________]
☐ Same as account email

Handling Submissions

In Email Notifications

Email field values appear in your notification:

New submission from Contact Form:

Reply-To Configuration

Set the email field as Reply-To address:

• Clicking “Reply” goes to submitter
