How to Lower Your Email Bounce Rate

Last verified · 2026-06-24

The short answer

Lower your bounce rate by verifying every address before sending, removing catch-all and role accounts from risky sends, authenticating your domain (SPF/DKIM/DMARC), and re-verifying aging lists since data decays monthly. Keep hard bounces under 2% to protect deliverability. Trackyr verifies emails at pull time (1 credit) and re-verifies continuously so lists don't silently rot.

Bounces are the deliverability killer

Mailbox providers read a high bounce rate as a signal that you're sending to a purchased or stale list — the hallmark of spam. Keep hard bounces under 2%. Above that, your inbox placement craters even for valid recipients.

Verify before every send

The single biggest lever is verifying addresses before they enter a campaign. Syntax, MX, and SMTP checks catch the addresses that would bounce, before the bounce ever happens. This is non-negotiable for cold lists.

Segment by risk

  • Send confidently to verified-valid addresses.
  • Hold or de-prioritize catch-all / accept-all results.
  • Drop role accounts (info@, sales@) from cold sends.
  • Remove disposable-domain addresses entirely.

Re-verify aging lists

A list verified six months ago isn't clean today. Data decays a few percent monthly. Re-verifying before reuse catches the addresses that died since your last send. Trackyr re-verifies continuously, so this happens without you remembering to.

Verifying at the source (1 credit per address in Trackyr) is far cheaper than the deliverability damage one bad batch causes.

Fix the foundations too

Authentication (SPF, DKIM, DMARC) and a warmed-up sending domain don't lower bounces directly, but they ensure your clean list actually reaches the inbox. Pair list hygiene with these and your deliverability holds.

// Common questions

Answered.

What bounce rate is too high?+

Aim to keep hard bounces under 2%. Above roughly 5% you risk serious deliverability damage and possible sending restrictions.

Will verification fix all my bounces?+

It eliminates most, by catching invalid mailboxes before you send. Catch-all domains remain uncertain, so segment those separately.

How often should I re-verify?+

Continuously, because lists decay monthly. Trackyr re-verifies on an ongoing basis rather than only at the moment you first pull a contact.
