The Email User Input Block is designed to collect email addresses from users while ensuring proper formatting. It provides built-in validation for email structure but does not verify if the email address exists or is active.

​

Key Features

• Email Format Validation: Automatically checks if the user-provided email is correctly formatted (e.g., user@example.com).
• Retry Message: Displays a retry message if the email format is invalid.

​

Limitations

• No Validity Check: The block does not verify if the email is active or belongs to a real domain.
• Advanced Validation: To check email validity, integrate with an email validation API using an HTTP Request block.

​

Example Usage

​

Basic Configuration

User prompt:
“Please enter your email address.”

Behavior:

• The block ensures the input is in the correct format (e.g., example@domain.com).
• If the format is incorrect, a retry message prompts the user to re-enter the email.

Advanced Validation with HTTP Request Block

1. Add an HTTP Request Block after the Email Input Block.
2. Configure the HTTP request to send the collected email address to an email validation API (e.g., Hunter.io, Mailboxlayer, etc.).
3. Process the response to determine the next flow in your agent.

Example HTTP Request Configuration:

• API Endpoint: https://api.mailboxlayer.com/check?access_key=YOUR_API_KEY&email={{email_variable}}
• Method: GET
• Variable: Replace {{email_variable}} with the variable storing the user’s email.
