Why bounces hurt so much
Every hard bounce tells Gmail, Outlook and Yahoo that you are sending to addresses you have not maintained. Too many, and they start treating your whole domain as low quality. The damage outlasts the campaign, because reputation is slow to rebuild.
How to lower your bounce rate
The fastest way to cut bounces is to remove the addresses that would bounce before you send. Verify your list to flag invalid, catch-all and disposable addresses, and verify new signups in real time so bad addresses never get in. For a deeper playbook, read how to reduce email bounce rate.
