EmailListVerify
Every email your AI agent collects gets validated through EmailListVerify before it reaches your database. Spam traps, disposable addresses, and undeliverable mailboxes are caught mid-conversation, keeping your sender reputation spotless and your lists squeaky clean.




From quick status checks to deep validation reports, your AI agent taps into EmailListVerify's verification engine to keep every email address honest.
EmailListVerify
Real scenarios where AI agents use EmailListVerify to intercept bad data at the source, so your outreach always reaches real people at real addresses.
A visitor requests your whitepaper and enters a throwaway email address. Your AI Agent verifies it through EmailListVerify's detailed endpoint and detects it is disposable. The agent politely asks for a permanent business email to receive the download link. You build a list of genuine prospects instead of ghost addresses that never open a single email.
A new user tries to create a free trial account with a misspelled email. Your AI Agent runs EmailListVerify's quick verification and discovers the domain does not have valid MX records. The agent suggests a correction and asks the user to re-enter their address. Your activation emails reach actual inboxes, improving trial-to-paid conversion rates.
Your blog has a subscribe widget where visitors opt into weekly updates. Your AI Agent validates each subscription email in real time. When EmailListVerify returns a 'failed' status for an address with an invalid mailbox, the agent blocks the signup and suggests the user double-check their entry. Your newsletter list stays clean from day one.

FAQs
EmailListVerify performs syntax validation, MX record lookup, SMTP handshake verification, spam trap detection, disposable email identification, and domain health analysis. The detailed endpoint returns all these results so your AI agent can make nuanced decisions about each address rather than relying on a simple pass-fail.
The quick endpoint returns a simple status: ok, failed, unknown, or incorrect. The detailed endpoint provides granular data including MX records, SMTP response codes, whether the address is a known spam trap, disposable status, and domain configuration details. Use quick for fast form validation and detailed for deeper list hygiene.
Real-time single-email verification typically returns in under 2 seconds. Your AI agent waits for the response before continuing the conversation, so the user experiences a natural pause comparable to any form submission. For most visitors, the verification is invisible.
No. Tars passes the email directly to EmailListVerify's API endpoint during the conversation. The verification result is used to guide the chat flow in real time. No separate copy of the email address is stored in Tars databases after the interaction concludes. EmailListVerify is also GDPR and DPA compliant.
Yes. You can configure the agent to accept unknown results with a cautionary tag, ask the user to confirm or re-enter their email, or escalate to a human reviewer. Unknown typically means the mail server did not provide a definitive answer, so the best handling depends on your risk tolerance.
Most email platforms like Mailchimp or HubSpot only perform basic syntax checks at signup. EmailListVerify goes further with SMTP verification, spam trap databases, and disposable email detection. Integrating it through your AI agent means bad emails are caught during the conversation itself, before they ever reach your email platform.
Log into your EmailListVerify dashboard and navigate to the API section to copy your key. In your Tars dashboard, go to Tools, select EmailListVerify, and paste the key. Once saved, attach the tool to your AI Agent Gambit. The agent will call EmailListVerify's endpoints whenever email validation is needed during a conversation.
Yes. EmailListVerify's detailed response flags role-based addresses. Your agent can be configured to reject these if your use case requires individual contacts, prompting the user to provide a personal business email. This is especially useful for B2B lead capture where you want to reach specific decision-makers.
Don't limit your AI Agent to basic conversations. Watch how to configure and add powerful tools making your agent smarter and more functional.
