Asana email verification with BillionVerify
Asana is a widely used project management platform where teams track tasks, projects, and goals. Connecting BillionVerify to Asana via n8n or Integrately lets you automatically validate contact email addresses stored in Asana tasks and custom fields, keeping client and stakeholder data accurate.
Why verify before the send
Project teams often store client or vendor email addresses directly in Asana tasks or portfolios. Unverified addresses lead to failed notifications, missed approvals, and wasted outreach. BillionVerify filters out invalid, disposable, and role-based addresses so every contact in your Asana workspace is reachable when it matters.
Ready-to-use n8n workflow
Import this workflow into n8n — it verifies every address with BillionVerify before Asana sends, so only deliverable contacts are emailed. Install the BillionVerify community node first, then add your API key. Adapted from this n8n template

}Workflow templates with Asana
Ready-to-use workflows that verify emails before Asana sends.
How it works
- 1
Connect Asana and BillionVerify in n8n or via the Integrately 1-click integration.
- 2
Trigger the workflow when a task is created or updated with an email address in a custom field.
- 3
Send the address to BillionVerify's API and receive a structured result indicating validity, type, and risk level.
- 4
Update the Asana task with a custom field or tag reflecting the verification outcome.
- 5
Route verified addresses to downstream tools; flag or skip unverified ones for manual review.
When to use this
Validate client emails on task creation
When a new Asana task is created with a client email in a custom field, automatically send that address to BillionVerify. Tasks with invalid emails get a warning tag, prompting the team to confirm the contact before outreach begins.
Sync verified contacts to email tools
Use an Asana-to-email-platform workflow that passes addresses through BillionVerify first. Only contacts that clear verification are added to campaign lists, protecting deliverability and keeping bounce rates within safe limits.
Periodic contact audits
Schedule a recurring workflow to pull all email addresses from Asana custom fields, verify them in bulk with BillionVerify, and update task custom field values to reflect current validity status.
FAQ
Can BillionVerify check emails stored in Asana custom fields?
Yes. Any workflow tool that can read Asana task data — including n8n and Integrately — can extract email values from custom fields and pass them to BillionVerify's API.
Is there a limit on how many addresses I can verify?
BillionVerify offers tiered plans that scale from small teams to enterprise volumes. Bulk verification lets you process entire contact lists in a single API call.
Does verifying emails in Asana require technical setup?
With Integrately's 1-click setup, no coding is required. For more custom logic — like conditional branching based on verification outcome — n8n's visual workflow builder is straightforward for non-developers.
What does BillionVerify return for each address?
Each check returns a status (valid, invalid, disposable, catch-all, role), SMTP reachability, and a risk score, giving you enough detail to decide how to handle each contact in Asana.
