Validate
Email Addresses with Confidence

Introduction Why Choose email-validator?

In today's digital landscape, accurate email validation is crucial. The email-validator library provides a robust and reliable solution for validating email addresses in Python applications. It ensures correct syntax, optionally checks deliverability, and supports internationalized domain names (IDN).

This library is ideal for registration forms, user account management, and any scenario where you need to verify the validity of an email address.

Key Features of email-validator

Syntax Validation: Ensures that an email address adheres to the correct format, reducing the risk of user input errors.

Deliverability Checks (Optional): Verify that the domain name can receive email, increasing the likelihood of successful communication. DNS queries can be cached to improve performance.

Internationalization Support: Correctly handles internationalized domain names and local parts of email addresses.

Friendly Error Messages: Provides clear and understandable error messages to guide users in correcting invalid email addresses.

Normalization: Normalizes email addresses to a standard format. (e.g., converting to lowercase, removing unnecessary escaping)

Installation Getting Started with email-validator

To install the email-validator library, use pip:

`bash pip install email-validator `

After installation, you can immediately start validating email addresses in your Python code.

Quick Start Example

Here’s a quick example of how to use the library to validate an email address and retrieve its normalized form:

`python from email_validator import validate_email, EmailNotValidError try: email_info = validate_email('example@example.com') print(f"Normalized email: {email_info.email}") except EmailNotValidError as e: print(f"Invalid email address: {e}") `

Customization Configuring Validation Options

The validate_email function offers several options to customize the validation process. These options allow you to tailor the validation to your specific needs, such as disabling DNS checks, allowing internationalized addresses, and more.

For example, you can disable DNS-based checks by setting check_deliverability=False in your validate_email call.
