Out of the numerous reasons, a few of the reasons why emails bounce back can be:

  • Invalid Email Address
  • Sender's IP address has been blocked
  • Email is being banned by the receiving server
  • The receiving server is overburdened
  • The inbox of the receiver is filled
  • The reputation score is low
  • The receiver includes an auto-responder
  • The email size is excessive

Certainly, an email checker can help companies and individuals avoid the major challenge of getting their IP addresses banned. In situations when their email marketing efforts receive a significant number of spam complaints or are forwarded to dubious email lists, there is a high possibility of getting their IP addresses banned.

What Is an Email Checker?

The Email Checker is a powerful outreach tool for validating email addresses. It's simple to use. All you need to do is simply enter the email address and click the check button. It shows you if the email address is valid or not. The Email Checker software examines your email list for incorrect or harmful emails and applies a range of various criteria to eliminate them. As a consequence, your email server's reputation is protected, and its deliverability rate is increased.

Advantages of Email Checker


Your mailing list's accuracy is critical; otherwise, your outreach effort may fail to produce the desired results, and your metrics will be off. You may avoid this by having a reliable email checker that can provide a list of validated email addresses in the first place. Apart from this, the email checker tool can assist you in the following ways:

  • Lowers the bounce rate
  • Helps keep costs down
  • Improves ROI
  • Lessens the time taken to correct bounces
  • Lowers spam reports
  • Increases engagement rates by identifying catch-all mail servers
