How to reduce email bounce risk before a campaign.
Bounces happen when mail can't be delivered. Most hard bounces are preventable with a few checks before you hit send.

Why bounces matter
High bounce rates tell mailbox providers that a sender isn't maintaining their list. Over time that can affect where your messages land.
Keep consent and list hygiene in mind
Verification checks whether an address can receive mail. It can't tell you whether the person wants your email. Permission-based lists bounce less and engage more.
Step by step
- 1
Verify the list before sending
Upload the list to MailGuard and wait for every address to be checked.
- 2
Remove invalid addresses
Exclude Failed results from your export. These are the most likely hard bounces.
- 3
Review Unknown and catch-all results
Keep Unknown addresses you trust and send to them in smaller batches.
- 4
Avoid purchased or scraped lists
These lists carry high bounce and complaint risk, and verification can't fix missing consent.
- 5
Repeat regularly
Re-verify lists that haven't been mailed in a few months.

Many senders aim to keep hard bounces well under 2%, but targets vary by provider and industry.
