Survicate email verification with BillionVerify
Survicate is a customer feedback and survey platform designed to capture insights at key moments in the customer journey. Pairing it with BillionVerify ensures that every email address collected through your surveys and feedback widgets is valid before being passed to marketing or CRM tools.
Why verify before the send
Feedback forms are a common entry point for disposable and fake email addresses — users who want to submit a response without being followed up. BillionVerify filters these out so your follow-up campaigns, NPS sequences, and customer success outreach land in real inboxes rather than bouncing or going unread.
Ready-to-use n8n workflow
Import this workflow into n8n — it verifies every address with BillionVerify before Survicate sends, so only deliverable contacts are emailed. Install the BillionVerify community node first, then add your API key.

}Workflow templates with Survicate
Ready-to-use workflows that verify emails before Survicate sends.
How it works
- 1
Connect Survicate to your automation layer via its native integrations or webhooks.
- 2
Add BillionVerify to the same workflow using the n8n community node, Integrately 1-click, or the REST API.
- 3
For each Survicate response containing an email, call BillionVerify to check deliverability.
- 4
Apply the verification result: allow valid addresses to continue downstream, tag risky ones, and suppress invalid or disposable ones.
- 5
Optionally write the verification verdict back to the contact record for segmentation and reporting.
When to use this
Screen emails collected from feedback widgets
When Survicate captures an email address through an in-app widget or exit survey, route it through BillionVerify before it flows to your CRM or email automation platform. Only verified addresses enter your contact database.
Improve deliverability of NPS follow-up emails
Before triggering follow-up emails to detractors or promoters from Survicate NPS data, validate the contact list with BillionVerify. Removing invalid addresses reduces bounce rates and protects your sender score during outreach.
FAQ
Which integration method works best with Survicate?
Integrately offers the fastest setup with no coding required. For complex conditional workflows — like routing based on survey score and email quality — n8n gives you full control.
Can BillionVerify detect role-based addresses like info@ or support@?
Yes. Role-based addresses are identified and returned with their own status flag, letting you decide whether to include or exclude them from your Survicate follow-up sequences.
How does verifying emails protect my sender reputation?
High bounce rates from invalid addresses signal mailbox providers that your sending practices are poor, which can lead to deliverability penalties. Removing bad addresses before sending keeps your bounce rate low and inbox placement high.
