Email list verifier  is the process of confirming that an email address is valid and still active. It’s a vital step to maintaining a clean mailing list, which can save marketers time and money, improve their ROI on marketing campaigns, and ultimately help them reach their business goals.

Invalid email addresses aren’t just bad for your deliverability, they also negatively impact your sender reputation. Sending emails to inactive or non-existent email addresses gives the impression that your company is a spammer, which can cause mail servers and antispam programs to take a dim view of future campaigns.
