The Email user block allows you to ask your user for an email address with automatic format validation. It provides a specialized input field that ensures proper email format before allowing the user to proceed.

​
Configuration Options

​
Custom Labels

  • Placeholder: Set the placeholder text shown in the email input field
  • Button Label: Customize the text shown on the submit button
  • Retry Message: Configure the error message displayed when an invalid email format is entered

​
Variable Integration

  • Save Answer: Choose a variable to store the collected email address

​
Validation Settings

The block automatically validates email format using standard email regex patterns, ensuring the input contains:
  • A valid username part before the @ symbol
  • An @ symbol
  • A valid domain part after the @ symbol
  • Flow
  • Bot
Email input in flow

Email Validation

​
Format Validation

The block automatically validates email format and displays a retry message when detection fails. Common validation rules include:
  • Presence of exactly one @ symbol
  • Valid characters in username and domain parts
  • Proper domain structure (e.g., domain.extension)

​
Validation Limitations

The block performs format validation only and does not verify:
  • Whether the email address actually exists
  • If the domain is valid and reachable
  • If the mailbox can receive messages

​
Advanced Email Verification

For comprehensive email validation beyond format checking, you’ll need to integrate with external services using a Webhook block:
  • Email deliverability services
  • Domain verification APIs
  • Real-time email validation services

​
Best Practices

​
User Experience

  • Use clear, friendly placeholder text (e.g., “Enter your email address”)
  • Provide helpful retry messages that guide users (e.g., “Please enter a valid email format”)
  • Consider the context of email collection (newsletter, account creation, contact)

​
Validation Messages

  • Keep retry messages concise and actionable
  • Avoid technical jargon in error messages
  • Provide examples of correct format when helpful
  • Use positive language that encourages correction

​
Data Collection

  • Use descriptive variable names for email storage
  • Consider privacy implications of email collection
  • Plan for downstream processing and validation needs
  • Implement appropriate data retention policies

Troubleshooting

​
Common Issues

Email not accepting valid addresses
  • Verify the email validation logic is working correctly
  • Check if special characters or international domains are causing issues
  • Test with common email providers (Gmail, Outlook, etc.)
Retry message not appearing
  • Confirm the retry message is configured in block settings
  • Check that invalid email formats trigger the validation
  • Verify the message text is not empty or contains only spaces
Variable not saving email
  • Ensure a variable is selected in the “Save Answer” dropdown
  • Verify the variable name doesn’t contain special characters
  • Check that the email passes validation before variable assignment
Mobile keyboard issues
  • Test on actual mobile devices for keyboard behavior
  • Ensure the input type is correctly set to ‘email’
  • Verify mobile browsers display the appropriate keyboard

​
Validation Considerations

International Email Addresses
  • Modern email validation should support international characters
  • Consider Unicode domain names and international TLDs
  • Test with various international email formats
Edge Cases
  • Very long email addresses (up to 254 characters)
  • Multiple dots in domain names
  • Plus signs and other special characters in usernames
  • Quoted strings in email addresses

​
Integration Tips

  • Sanitize email data before storing in external systems
  • Consider email normalization (lowercase, trim whitespace)
  • Plan for email verification workflows post-collection
  • Implement proper error handling for downstream services
  • Use email data responsibly and in compliance with privacy regulations
