Use Cases

Clean data from the first interaction

Real scenarios where AI-powered email verification happens during the conversation, not after, ensuring every address captured is worth a follow-up.

Lead Capture That Rejects Junk Instantly

A visitor fills out your chat lead form with a random string at a fake domain. Your AI Agent sends the email to Kickbox's verification API, gets back an 'undeliverable' result, and immediately asks for a valid address. The visitor corrects it to their real email. Your sales team only sees verified leads in the CRM, and your outbound campaigns never bounce.

Signup Flow With Built-In Typo Correction

A new customer types 'jane@yaho.com' during account registration through your AI chatbot. Kickbox returns a did_you_mean suggestion of 'yahoo.com.' The agent responds: 'Looks like there might be a typo. Did you mean jane@yahoo.com?' One click and the customer proceeds with the right address. No lost activation emails, no support tickets about missing confirmations.

Webinar Registration Quality Gate

Your marketing team runs a webinar and uses your AI agent to handle registrations. For every email submitted, the agent checks Kickbox's Sendex quality score. Addresses scoring below 0.5 get flagged as low quality, and the visitor is asked to provide a work email instead. Your webinar list fills with high-quality contacts, and post-event nurture campaigns see higher open rates.

FAQs

Frequently Asked Questions

How does the AI agent verify emails using Kickbox during a conversation?

When a visitor provides their email, the agent sends it to Kickbox's Single Verification API in real time. Kickbox checks SMTP deliverability, domain validity, and mailbox existence, then returns a result (deliverable, undeliverable, risky, or unknown) along with a quality score and flags. The agent uses this response to either accept the email or ask for a correction.

What is the Sendex score and how does the agent use it?

Sendex is Kickbox's proprietary quality score ranging from 0 (lowest quality) to 1 (highest quality). It evaluates factors beyond simple deliverability, such as engagement history patterns. You can configure the agent to accept only emails above a minimum Sendex threshold, like 0.6, ensuring your list quality stays high.

Can the agent suggest corrections for misspelled email domains?

Yes. Kickbox returns a did_you_mean field when it detects a likely typo in the email domain. For example, if someone types 'user@gmial.com,' the API suggests 'gmail.com.' The agent presents this suggestion to the visitor conversationally and lets them confirm or re-enter their address.

Does Tars store the email addresses sent to Kickbox?

Tars passes the email to Kickbox for verification during the conversation and uses the result to proceed. Email addresses entered during conversations are handled according to your Tars data retention settings. Kickbox's own retention policies apply on their end, and they do not share verification data with third parties.

How fast is the Kickbox verification during a live chat?

Kickbox's single verification typically responds within 1 to 3 seconds. The SMTP verification timeout defaults to 6,000 milliseconds but can be configured up to 20,000 milliseconds via the timeout parameter. In practice, customers experience a brief pause that feels natural within a conversation flow.

Can the agent differentiate between role-based and personal emails?

Yes. Kickbox's response includes a 'role' boolean flag that identifies addresses like info@, support@, and admin@. The agent can be configured to accept role-based emails with a note, reject them entirely, or ask for a personal address depending on your lead qualification rules.

What happens when Kickbox returns an 'unknown' result?

An 'unknown' result means Kickbox could not definitively verify the address, often due to a catch-all mail server or temporary SMTP issues. You can configure the agent to accept unknowns with a lower confidence flag, retry verification, or ask the visitor to confirm their address is correct.

How is this different from just adding Kickbox to my form backend?

Backend validation happens after form submission and often shows a generic error page. With Tars, verification happens inside the conversation. The agent explains the issue in plain language, suggests corrections, and collects a valid address without the visitor ever leaving the chat. It is a smoother experience with higher completion rates.
