  1. 01

    Enter your campaign numbers

    Total emails sent and total bounced.

  2. 02

    We calculate your bounce rate

    Bounce rate = (bounced / sent) x 100.

  3. 03

    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.

Under 2% is considered healthy. Between 2-5% needs attention. Above 5% is critical and you should pause sending and clean your list immediately.
