About this integration

Connect Kickbox to Definable to triage inboxes, draft and queue follow-ups, classify and route incoming threads. Personas call Kickbox's 2 tools directly from chat or scheduled flows. Hand off to an email persona to triage, draft, and route — with you in the loop on every outbound.

Connect Kickbox to Definable and it becomes a set of typed tools your agents plan with — triggered by events, run on schedules, or invoked mid-conversation. Every write is checked by the verifier before it lands.

The Kickbox toolbox.

Every Kickbox capability your agents can call, each with a typed schema the planner reads. The router picks the right tool per step; the verifier checks the result.

Check Disposable Email

Tool to check if an email address or domain is from a disposable email service. Use when you need to validate whether an email is temporary or throwaway (e.g., mailinator.com, trashmail.com). This is a free public endpoint that does not require authentication.

Kickbox Single Verification

Tool to verify a single email address via Kickbox. Use when you need real-time validation of an individual email before critical workflows.

Questions, answered.

What teams ask before connecting Kickbox.

01 What can I automate with Kickbox on Definable?

Anything Kickbox exposes through its API. Common email workflows on Definable include triage inboxes, draft and queue follow-ups, classify and route incoming threads. Personas can call any of the 2 Kickbox tools directly, then chain the result into another integration without you writing code.

02 How does Kickbox authentication work?

Kickbox uses API_KEY on Definable. You connect once from the integrations page, scoped to the permissions you choose, and from then on any persona that has the integration enabled can act on your behalf. Tokens are encrypted at rest and rotated automatically.

03 Is the Kickbox integration included in my Definable plan?

Yes — every Definable plan, including Starter, includes access to all 2 Kickbox tools. You only need a separate Kickbox subscription if Kickbox itself charges per seat or per API call.

04 Is using Kickbox through Definable secure?

Every call from a persona to Kickbox is logged with the user, persona, prompt, and response. Tokens never leave Definable's secrets vault, scopes are configurable per persona, and you can revoke access at any time from the integration page.

05 How do I get started with Kickbox on Definable?

Sign up for Definable, open the integrations page, find Kickbox, and connect via OAuth or API key. You can immediately attach Kickbox to any persona and start running workflows. The free Starter plan includes 5,000 credits/month.

06 What Kickbox actions does Definable expose?

Definable exposes all 2 Kickbox actions as callable tools — including `Check Disposable Email`, `Kickbox Single Verification`. Each tool gets a typed parameter schema so personas know exactly how to call it.
