Moosend email verification with BillionVerify
Moosend is an email marketing automation platform for building campaigns, automations, and subscriber journeys. Integrating BillionVerify keeps your Moosend lists clean by removing invalid, disposable, and undeliverable addresses before they damage your sender reputation.
Why verify before the send
Even a small percentage of bad addresses in a Moosend campaign can push your bounce rate above ISP thresholds, triggering spam filtering that hurts deliverability for your entire sending domain. Verifying addresses with BillionVerify before import or send protects your reputation and improves open rates.
Ready-to-use n8n workflow
Import this workflow into n8n — it verifies every address with BillionVerify before Moosend sends, so only deliverable contacts are emailed. Install the BillionVerify community node first, then add your API key.

}Workflow templates with Moosend
Ready-to-use workflows that verify emails before Moosend sends.
How it works
- 1
Export a subscriber list or connect a Moosend sign-up trigger to your n8n or Integrately workflow.
- 2
Pass each email address to BillionVerify, which checks deliverability, domain health, disposable email providers, and SMTP reachability.
- 3
Receive a verdict for each address: valid, invalid, risky (catch-all, role-based, disposable).
- 4
Filter the results and import only verified valid addresses back into your Moosend list or automation.
- 5
Set up a recurring schedule to re-verify older segments and keep your list hygiene consistent over time.
When to use this
Verify contacts before importing to Moosend
Run any new contact list through BillionVerify before uploading it to Moosend. Strip out invalid and disposable addresses so your deliverability metrics stay healthy from the first send.
Validate new subscribers in real time
Connect Moosend sign-up forms to BillionVerify via n8n or Integrately. As each subscriber submits their email, verify it instantly and only add confirmed valid addresses to your Moosend audience.
Periodically re-clean existing lists
Export dormant or older segments from Moosend, verify them in bulk with BillionVerify, and re-import only the addresses that are still reachable — maintaining list freshness without manual review.
FAQ
Will verifying my list improve Moosend campaign deliverability?
Yes. Removing invalid and undeliverable addresses lowers your hard bounce rate, which is one of the primary signals ISPs use to assess sender reputation. Lower bounces mean more of your emails reach the inbox.
Can I verify addresses at the Moosend sign-up form stage?
Yes. Use n8n or Integrately to intercept new sign-ups, run them through BillionVerify in real time, and only subscribe the address in Moosend if it passes verification.
What is a role-based email and why should I filter it?
Role-based addresses like info@, sales@, or support@ are shared mailboxes rather than individual inboxes. They have lower engagement, higher complaint rates, and can trigger spam filters, so filtering them improves campaign performance.
Is there a limit on how many addresses I can verify at once?
BillionVerify's bulk API supports large list uploads — hundreds of thousands of addresses — making it practical for full list hygiene passes before major Moosend campaigns.
