What is the consequence of a high bounce rate on email campaigns?

A high bounce rate in email campaigns has a significant implication for sender reputation. When a large number of emails sent from a domain bounce back, it signals to Internet Service Providers (ISPs) and email filtering systems that the sender may not maintain a clean and engaged email list. This negativity arises because ISPs often associate high bounce rates with poor list management practices, such as sending emails to outdated or non-existent addresses.

As a consequence, the sender's reputation may suffer, leading to future emails being filtered into spam folders or even being blocked completely by ISPs. This operational impact extends beyond just the current campaign; it can affect future deliverability rates and the overall success of email marketing efforts. Thus, managing bounce rates is crucial to maintaining a solid reputation and ensuring successful future campaigns.
