Cliengo email verification with BillionVerify
Cliengo is a conversational CRM and chatbot platform widely used in Latin America to capture leads through website chat widgets, WhatsApp, and landing pages. When Cliengo collects an email during a conversation, BillionVerify verifies it before the lead enters your pipeline, ensuring your sales team works only with reachable, genuine contacts.
Why verify before the send
Chat-captured leads are especially prone to fake or mistyped emails — visitors in a hurry often enter placeholder addresses just to move past a form. Sending follow-up emails to those addresses wastes your sales team's time and harms your domain's sender reputation. BillionVerify validates every Cliengo-captured email at the moment it is collected, so your CRM stays clean and your follow-ups land in real inboxes.

How it works
- 1
A visitor interacts with Cliengo's chatbot or landing page form and provides their email address.
- 2
Cliengo captures the lead and an n8n or Integrately automation is triggered.
- 3
The email is sent to BillionVerify, which checks DNS validity, SMTP deliverability, and screens for disposable or role-based domains.
- 4
Verified leads are added to your CRM or email list; unverified leads are tagged or excluded for sales review.
- 5
Your team receives only quality leads with reachable emails, improving follow-up success rates from the first contact.
When to use this
Filter invalid emails from chatbot lead captures
When Cliengo's chatbot collects an email during a website conversation, BillionVerify immediately checks it. Leads with invalid or disposable addresses are flagged before they reach your sales pipeline, saving your team from chasing dead ends.
Protect your CRM from low-quality contacts
As Cliengo pushes new leads to your CRM, BillionVerify acts as a quality gate. Only verified email addresses make it through, keeping your contact database accurate and your email engagement metrics meaningful.
FAQ
Does BillionVerify support Spanish-language or Latin American email domains?
Yes. BillionVerify verifies emails globally, including regional domains common in Latin America such as .com.ar, .com.mx, and .com.br, making it a strong fit for Cliengo's core market.
Can I verify WhatsApp-collected emails from Cliengo?
Yes. Any email Cliengo captures — whether from a web chat, WhatsApp flow, or landing page — can be routed through BillionVerify before being stored or acted on.
What should I do with leads that have catch-all email domains?
BillionVerify labels catch-all addresses distinctly. You can choose to pass them through to your sales team with a warning, or exclude them from automated email sequences while keeping them for manual outreach.
How does verification help my Cliengo ROI?
Fewer bounces mean better inbox placement for future campaigns, and your sales team spends time on leads who can actually be reached — directly improving conversion rates from chatbot-captured contacts.
