It meets the desired form and the domain name resolves. On the other hand,, meets both requirements for a valid email address.
A string containing an email address may meet the specified form of an email address, but still cannot be considered a proper email address, because the domain doesn't resolve.įor instance, meets the specified form of an email address, but isn't valid because the domain name ( ) doesn't exist, therefore doesn't resolve and the example email address can't send and receive email messages. On the other hand, email address validation sometimes can be a lot more complex. If you'd like to read more about validating email addresses with RegEx - read our Python: Validate Email Address with Regular Expressions! It is a well-known technique, easy to write and maintain, and doesn't consume too much computing power to execute. We usually use some kind of Regular Expression (RegEx) to validate the correct form of email addresses and it is a great choice if you only need to make sure that some email address meets the required form. email-validator vs RegEx for Email Validation įor example, it won't properly validate the To: line in an email message (for example, To: Example Name ). It is important to mention that this library is not designed to work with an email address that doesn't meet the form of.
The problem lies in the fact that different Unicode strings can look and mean the same to the end-user, so the normalization should ensure that those strings will be recorded in the same way because they actually represent the same domain. In more complex cases of normalization, where the domain part includes some Unicode characters, normalization covers a variety of conversions between Unicode and ASCII characters. In its simplest form, the normalization of an email address implies lowercasing the domain of an email address (the sequence after the sign), because it is case-insensitive. That is important because the email address must meet the required form and have a resolvable domain name at the same time to be considered valid. It performs two types of validation - syntax validation and deliverability validation. What is email-validator?Īs we've previously stated, email-validator is a robust Python library that validates email addresses.
#Bulk email validator how to
We'll go over these with practical examples that will help you understand how to use email-validator. In this guide, we'll go over the basics of this library, discover when and why you could use it, as well as when not to. It is an easy to use, yet robust, Python library used to validate email addresses. That must be performed efficiently and safely. You need to validate if an email address is real by checking whether if it meets the required form and can receive email messages.
#Bulk email validator registration
Whether you are creating a registration form for your website or you just need to delete all invalid email addresses from your mailing list, you can't help but perform the process of email validation.
