Dust email verification with BillionVerify
Dust is an AI workspace platform that lets teams build and deploy custom AI assistants trained on their internal knowledge. When those assistants collect or process user emails, verified addresses ensure AI-driven workflows reach real inboxes rather than bouncing or landing in spam traps.
Why verify before the send
AI assistants in Dust often trigger downstream notifications, follow-ups, or data-enrichment tasks tied to an email address. Sending to invalid or disposable addresses wastes API calls, skews analytics, and degrades the sender reputation of any connected email service. BillionVerify filters out bad addresses before they enter your AI pipeline.
Ready-to-use n8n workflow
Import this workflow into n8n — it verifies every address with BillionVerify before Dust sends, so only deliverable contacts are emailed. Install the BillionVerify community node first, then add your API key. Adapted from this n8n template

How it works

- 2
Add a trigger from Dust (via webhook or n8n's HTTP Request node) that fires whenever an email address is captured or processed.
- 3
Pass the email address to the BillionVerify Verify Email action.
- 4
Inspect the result fields—valid, disposable, role, catch-all—and branch your workflow accordingly.
- 5
Allow only verified addresses to proceed into Dust assistants or downstream sending tools.
When to use this
Clean emails before AI-assisted outreach
When a Dust assistant generates personalized outreach sequences, route the recipient list through BillionVerify first. Catch invalid, role-based, and catch-all addresses so every AI-crafted message reaches a deliverable inbox.
Validate user input captured by AI assistants
Dust assistants that collect email addresses via conversational interfaces can pass each address to BillionVerify in real time, rejecting disposable or malformed entries before they pollute your CRM or mailing list.
FAQ
Does BillionVerify work with Dust's API?
Yes. Use n8n's HTTP Request node or the BillionVerify REST API to call verification from any Dust-connected workflow, regardless of how Dust surfaces the email address.
Can I verify addresses in bulk from a Dust data source?
Absolutely. Export the address list from your Dust knowledge base or conversation logs, run a bulk verification job via BillionVerify's REST API, and reimport only the clean addresses.
What counts as an invalid address?
BillionVerify flags addresses that fail DNS or SMTP checks, belong to disposable-email providers, are role accounts like info@ or admin@, or resolve to catch-all mail servers—helping you decide how much risk to accept.
