Bouncer

Bouncer helps you maintain a healthy subscriber list by identifying invalid, fraudulent, or malicious email addresses. You can upload bulk lists for cleaning or use the API to verify emails at the point of sign-up.

The Toxicity Check feature goes beyond basic verification by spotting spam traps and addresses belonging to frequent complainers. This prevents your newsletters from being flagged as spam and protects your sender reputation.

You can monitor your performance with the Deliverability Kit, which tests inbox placement and tracks blocklists. This ensures your content actually reaches your audience instead of getting lost in junk folders.

Email Engagement Insights provide data on when subscribers last opened or clicked an email. This allows you to segment your list based on activity and remove inactive contacts to improve your overall metrics.

The platform integrates directly with popular marketing tools and CRMs to automate the cleaning process. You can also enrich subscriber data with public company information to better understand your audience.
