Every email your AI agent collects gets verified before it touches your database. Real-time validation catches typos on signup forms, batch processing cleans imported lists, and toxicity checks flag spam traps hiding in purchased contacts. Your sender reputation stays protected while your pipeline fills with deliverable addresses.




Your AI agent validates addresses the moment they are captured, runs bulk list cleaning in the background, and screens for toxic contacts that could wreck your deliverability.

Real scenarios where AI catches invalid addresses at the point of entry, protects sender reputation before campaign launches, and screens vendor lists for hidden threats.
A visitor enters 'john@gmial.com' in your contact form. Your AI Agent intercepts the submission, calls Bouncer's Verify Email endpoint, receives an 'undeliverable' status because the domain has no valid MX records, and prompts the visitor: 'Did you mean john@gmail.com?' The corrected address enters your CRM. Your marketing team never wastes a nurture email on a dead address, and the lead does not disappear into a bounce void.
Marketing prepares to send a product announcement to 40,000 subscribers. Your AI Agent submits the list to Bouncer's Create Batch Request endpoint, processes all addresses at up to 100,000 per hour, and pulls back segmented results. The campaign sends only to the 35,000 verified deliverable addresses. Sender reputation stays pristine, inbox placement rates climb, and your ESP does not flag the account for excessive bounces.
Your sales team purchases a lead list from an industry event sponsor. Your AI Agent submits the addresses to Bouncer's Toxicity List Job endpoint, scans for spam traps, known complainers, and breached addresses on a 1-to-5 toxicity scale, and quarantines the high-risk contacts. The clean portion enters your CRM for outreach. Your domain avoids blocklisting from a single bad import.

FAQs
Real-time verification via the Verify Email endpoint returns results within 10 seconds by default. You can adjust the timeout parameter down to 5 seconds for faster form validation or up to 30 seconds for thorough SMTP-level checks on slower mail servers. The agent waits for the result before accepting or rejecting the address.
Bouncer's response includes detailed reason codes covering syntax errors, invalid domains, nonexistent mailboxes, and disposable email providers. The agent interprets these signals. A domain typo like 'gmial.com' triggers a correction suggestion, while a valid domain with a nonexistent mailbox prompts the visitor to double-check their username.
Toxicity analysis identifies addresses that pass deliverability checks but are dangerous to email. This includes spam traps planted by ISPs, known complainers who mark messages as spam, litigators, and addresses leaked in data breaches. Use it whenever you acquire contacts from third-party sources, purchased lists, or event signups where data quality is uncertain.
Tars passes addresses to Bouncer's API and receives verification results, but does not maintain a separate database of verified emails. Bouncer processes addresses in GDPR-compliant EU data centers and anonymizes them after verification. Verified results flow into your CRM or marketing platform, not into Tars storage.
Bouncer's Create Batch Request endpoint accepts up to 500,000 email addresses per job and processes them at approximately 100,000 per hour. The agent monitors job status and retrieves results as they complete. For larger lists, split them into multiple batch requests and the agent manages the queue.
Yes. The Verify Domain endpoint identifies catch-all configurations where the mail server accepts messages to any address at the domain, making individual mailbox verification unreliable. Bouncer is recognized for accurately handling catch-all domains hosted on Google Workspace and Microsoft 365, which many competitors cannot verify.
The dashboard requires manual CSV uploads and downloads. Tars embeds verification into your live workflows. Form submissions validate in real time during the conversation, batch imports trigger automatically when new lists arrive, and results route directly to your CRM. No manual file handling or tab switching required.
Yes. Configure source-specific rules in the Tars dashboard. Chatbot-collected emails might require only deliverability checks, while imported event lists trigger full toxicity analysis. High-value form submissions can run both verification and domain checks. Each source gets the level of scrutiny your business needs.
Don't limit your AI Agent to basic conversations. Watch how to configure and add powerful tools making your agent smarter and more functional.
