An email list checker is an online tool that identifies invalid or high-risk emails before you send your email campaigns. It’s important to clean and verify your list before sending email messages, as doing so prevents emails from reaching the inbox and can damage your deliverability rate and email reputation score.

Invalid, outdated email addresses are a common reason for high bounce rates in email marketing. Over time, email addresses become invalid as people change jobs or their inboxes shut down. These invalid email addresses can also be spam traps, abuse emails and disposable addresses that have been set up for one-time use, then deleted. The best email verification software identifies these types of addresses and marks them accordingly, improving the quality of your list and protecting your email sender reputation.

Why You Need an Email List Checker for Your Marketing Campaigns

The top email validation tools allow you to quickly and easily verify an entire list of email addresses in a few clicks. Some even offer free trials so you can test them out before spending any money. To get started, simply upload your list and select a verification method. Then, the tool will process your list and return a clean version that you can download.

They are easy to use and can be integrated with your website or registration forms via API, JavaScript, Zapier or NeverBounce’s API wrappers.
