Firmao email verification with BillionVerify
Firmao is a CRM and business management platform used by small and medium businesses to track leads, manage customer relationships, and run sales pipelines. Connecting it to BillionVerify ensures that every email address entering your CRM is valid, reachable, and free of disposable or role-based addresses — keeping your contact database clean from the start.
Why verify before the send
A CRM is only as useful as the data inside it. Invalid or fake email addresses silently degrade your outreach, inflate pipeline numbers, and waste your sales team's time. BillionVerify checks each address for deliverability, catch-all status, disposable domains, and role accounts before they pollute your Firmao records.
Ready-to-use n8n workflow
Import this workflow into n8n — it verifies every address with BillionVerify before Firmao sends, so only deliverable contacts are emailed. Install the BillionVerify community node first, then add your API key.

}Workflow templates with Firmao
Ready-to-use workflows that verify emails before Firmao sends.
How it works
- 1
Connect Firmao and BillionVerify in n8n using the BillionVerify community node, or set up a 1-click automation via Integrately.
- 2
Choose a trigger — new contact created, lead imported, or a scheduled audit of existing records.
- 3
BillionVerify checks each email address for syntax, domain validity, MX records, disposable domains, catch-all behaviour, and role accounts.
- 4
The verification result is written back to the Firmao contact record as a custom field or tag.
- 5
Contacts marked as invalid or risky are flagged, quarantined, or removed based on the workflow rules you define.
When to use this
Clean new leads at the point of entry
When a lead lands in Firmao from a web form or import, trigger BillionVerify automatically. Only addresses that pass verification get saved as active contacts, preventing bad data from accumulating over time.
Audit existing contact lists
Run a bulk verification pass against your current Firmao contacts. Flag undeliverable or risky addresses so your sales reps focus only on genuine prospects and your email campaigns avoid unnecessary bounces.
Guard CRM data quality during imports
Before importing a purchased or scraped list into Firmao, route it through BillionVerify to strip invalid, disposable, and catch-all addresses, protecting your sender reputation before the first email goes out.
FAQ
How does BillionVerify connect to Firmao?
You can connect them through the BillionVerify n8n community node, a 1-click Integrately automation, or by calling the BillionVerify REST API directly from any workflow that reads and writes Firmao data.
Will verifying contacts slow down lead capture?
No. BillionVerify returns results in milliseconds, so real-time verification at lead creation adds no noticeable delay to your Firmao workflows.
What types of addresses does BillionVerify catch?
It detects invalid syntax, non-existent domains, disposable email services, role-based addresses like info@ or sales@, and catch-all domains that accept any address regardless of whether a real inbox exists.
Can I verify my entire existing Firmao database?
Yes. Export your contacts, run them through BillionVerify's bulk API, and import the results back. Or build an n8n workflow that pages through Firmao records and verifies them in batches.
