Email Bounce Rate Calculator
Hard bounces as a deliverability signal.
Bounce rate
2.5%
0.75% hard
Hard bounces at 0.75% are within a healthy range. Soft bounces are usually temporary, but an address that soft bounces repeatedly should be treated as hard and removed.
How the Email Bounce Rate Calculator works
A hard bounce rate above 2% is a deliverability problem, not a list problem — mailbox providers read it as evidence you are mailing addresses you should not have. The fix is upstream, in how the addresses were collected.
Not financial advice. Marketplace fees change, and they vary by country, plan and seller status. Every rate here is an editable default, not a quoted price — check the platform's current fee schedule before you price a product against it. This is not tax or business advice.
Frequently asked questions
What is the difference between hard and soft bounces?
Hard bounces are permanent — the address does not exist. Soft bounces are temporary, such as a full mailbox or a server issue. Repeated soft bounces should be treated as hard.
What bounce rate is acceptable?
Under 2% total, with hard bounces well under that. Above it, mailbox providers begin filtering your mail generally, which affects the subscribers who do want it.
What causes high hard bounce rates?
Purchased lists, typos at signup, and old addresses that were never cleaned. Double opt-in and real-time validation at the form eliminate most of it.
Should I re-send to soft bounces?
Your platform will usually retry automatically. What matters is removing addresses that soft bounce consistently — they behave like hard bounces to the receiving server.
