Compare against benchmarks
See how you compare to industry averages and what your rate means for deliverability.
Why this matters
A bounce rate above 2% damages your sender reputation. Above 5% and you risk getting your domain blacklisted. Monitoring bounce rates after every campaign tells you whether your email list is healthy and whether you need to clean it.
Track bounce rates in real time
Sendbox shows bounce rate per campaign and per mailbox in real time, so you spot list and reputation issues early.
Campaign analytics
Bounce rates tracked across every campaign you send
Per-mailbox bounce rate
