Key features
Bouncer
- List verification
- Upload a CSV and get each address back as deliverable, risky, undeliverable or unknown, with reasons. Catch-all domains get a deeper check.

- Synchronous and batch endpoints verify addresses from your own app, and an MCP server connects Bouncer to ChatGPT, Claude and other AI tools.
- Toxicity Check
- Scores each address from 0 to 5 for risks such as breached or widely shared addresses, known complainers and likely spam traps.
- Bouncer Shield
- Checks addresses as they are typed into sign-up forms and can block invalid, malicious or fraudulent entries by address or IP.
- Deliverability Kit
- Sends test emails to see whether they land in the inbox or spam, checks SPF, DKIM and DMARC, and monitors IPs and domains on blocklists.
- AutoClean and integrations
- Connects to email and CRM tools such as Mailchimp, HubSpot and Klaviyo to verify lists where they live, and AutoClean verifies a connected CRM without manual uploads.
