Verify If an Email Address Is Genuine: Try It for Free

The best free email verification tools typically perform the following tasks:

First, they check if an address is valid by testing its syntax (user name, address sign, and domain) to see if it is formatted correctly. They then connect to the mail server over SMTP and simulate sending an email to make sure the mailbox exists and is capable of receiving messages. They then perform a blacklist check, identifying known bots, spam traps, and other fake addresses. They also perform a toxicity test, checking for keywords that indicate the email is likely to be abused or spammed.

In addition to the above, some free email verification tools are also capable of removing role addresses. This is helpful because these types of email addresses are notorious for increasing your spam complaint rate. This feature is useful for businesses that want to limit the amount of spam they receive.

The best email validation software offers a variety of pricing options to suit different needs. Most offer a free trial period to help you decide which solution is best for your business. Many offer API integrations to allow you to verify emails from within other applications and platforms. Some are even free to use for smaller lists.
