What bounce rate would cause deliverability concerns?

A bounce rate over 10% is generally considered to raise significant deliverability concerns. Bounce rates indicate the percentage of emails that were not successfully delivered to recipients. When a high percentage of emails are bouncing back, it often suggests issues related to your email list quality, such as outdated or invalid email addresses. A bounce rate above 10% may signal to internet service providers that your mailing practices are questionable, potentially leading to your emails being filtered or blocked.

Maintaining a lower bounce rate is crucial for ensuring that your emails reach intended subscribers. As bounce rates increase, it becomes increasingly challenging to maintain a good sender reputation, which is vital for successful email marketing. Therefore, a bounce rate exceeding 10% is a critical threshold that marketers should monitor closely to avoid negatively impacting their email deliverability and overall marketing effectiveness.
