Clickup email verification with BillionVerify
ClickUp is an all-in-one productivity platform where teams manage tasks, projects, docs, and goals. When contacts or leads flow into ClickUp from forms, integrations, or automations, unverified email addresses silently undermine every follow-up you plan to send.
Why verify before the send
Invalid, disposable, or catch-all email addresses attached to ClickUp tasks mean your outreach bounces before it starts. BillionVerify checks every address for deliverability issues — including role-based inboxes and temporary domains — so the contact data living in your tasks is accurate and actionable from the moment it arrives.
Ready-to-use n8n workflow
Import this workflow into n8n — it verifies every address with BillionVerify before Clickup 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
- 1
Connect ClickUp and BillionVerify through the n8n community node, Integrately (1-click setup), or the BillionVerify REST API.
- 2
Set a trigger — such as a new task created, a custom field updated, or a form submission received — in your ClickUp workspace.
- 3
BillionVerify checks the email address for syntax errors, DNS validity, disposable domains, role-based patterns, and catch-all status.
- 4
The verification result (valid, invalid, risky, catch-all) is written back to the ClickUp task as a custom field or comment.
- 5
Downstream automations route, tag, or discard tasks based on verification status, keeping only deliverable contacts in your active workflows.
When to use this
Clean incoming lead data automatically
When a new task is created in ClickUp from a lead form or CRM sync, trigger BillionVerify to validate the contact's email. Flag or remove invalid addresses before they pollute your list and inflate your bounce rate.
Protect project communication workflows
Teams often store client and stakeholder emails directly in ClickUp tasks. Verify those addresses on entry so automated status updates, invoices, and notifications actually reach the people who need them.
Maintain data hygiene across recurring automations
Run periodic verification passes on email fields stored in ClickUp custom fields, surfacing stale or risky addresses before campaign launches or scheduled outreach sequences.
FAQ
Does BillionVerify work with ClickUp custom fields?
Yes. Using n8n or the REST API you can read email values from any ClickUp custom field, verify them, and write the result back — all without leaving your existing workflow structure.
Can I verify emails in bulk from a ClickUp list?
Absolutely. Export your list or iterate over tasks via the API, send addresses to BillionVerify in batch, and update each task with its verification status in a single automated run.
What does 'catch-all' mean and should I send to those addresses?
A catch-all domain accepts any email without confirming the mailbox exists. BillionVerify flags these so you can decide whether to send cautiously or exclude them from high-stakes campaigns.
Is there a limit on how many emails I can verify?
BillionVerify offers flexible credit-based pricing that scales from hundreds to billions of verifications, making it suitable for small ClickUp teams and large enterprise deployments alike.
