This is a passive feature available for customers on all plans.
​
Our system analyzes bounce data in real-time to automatically skip any known high-risk recipients (based on the data from our logs and millions of emails sent) - thus protecting emails from getting bounced - reducing your bounce rate and helping you protect your sender reputation.

The lead will also be skipped if it is added to the user's blocklist after being added to a campaign.

You will still need to use email verifiers before uploading leads to Instantly, but this feature will further improve your deliverability.

Bounce shield is enabled by default, but users can turn it off from Advanced campaign options.
