How to reduce email bounce rate
Mailbox providers read your bounce rate as a measure of how much you care about your list. Practical steps to keep it under control.
Why bounce rate decides your deliverability
Every hard bounce tells the receiving provider that you sent to an address you didn't verify. A few are normal; a pattern reads as a purchased or scraped list, and providers respond by routing the rest of your mail to spam — including the mail to perfectly good addresses.
Industry rule of thumb: stay under 2%. Past 5%, reputation damage compounds and takes weeks of good behaviour to unwind.
Stop bad addresses at the door
Most bounces enter through forms: typos (gmial.com), keyboard mash, and deliberately fake entries. Validate at collection — syntax, DNS and a typo suggestion at the form catches the majority for free.
Validate on import as well. Any list older than a few months has decayed — people change jobs, abandon mailboxes, and providers recycle addresses. Cleaning a list before its first campaign is the single highest-leverage deliverability move.
Retire addresses before they turn
Suppress every hard bounce immediately and permanently — a second send to a hard-bounced address is a red flag providers remember.
Watch the silent segment too: addresses that never open or click for months are the next hard bounces. Winding them down with a re-engagement pass keeps the list honest before the bounce, not after.
