Email marketing has become an essential part of the marketing strategy for businesses of all sizes. However, despite the many benefits of email marketing, there are still some challenges that you might face, such as email bounces. An email bounce is when an email that you have sent is returned to you because it was not delivered to the recipient's inbox. This can be due to a variety of reasons such as invalid email addresses, full inboxes, or spam filters.

While email bounces can be frustrating, they can also be damaging to your business. If you continue to send emails to invalid email addresses or those that bounce, you could be damaging your sender reputation. This can lead to your emails being marked as spam, and your email address being added to a blacklist.
