Orbit email verification with BillionVerify
Orbit is a community growth platform that helps developer-focused companies track member activity, measure engagement, and nurture their communities across GitHub, Slack, Discord, and other channels. BillionVerify keeps member email records accurate so outreach and digest emails actually reach your community.
Why verify before the send
Community members often join with personal, work, or throwaway email addresses that become stale over time. Sending newsletters or event invites to invalid addresses damages your domain reputation and leaves members unreached. BillionVerify validates addresses at the point of member registration and on a scheduled basis to keep your Orbit workspace clean.
Ready-to-use n8n workflow
Import this workflow into n8n — it verifies every address with BillionVerify before Orbit sends, so only deliverable contacts are emailed. Install the BillionVerify community node first, then add your API key.

}Workflow templates with Orbit
Ready-to-use workflows that verify emails before Orbit sends.
How it works
- 1
Connect BillionVerify using the n8n community node, Integrately 1-click automation, or the REST API.
- 2
Set up a trigger for new member additions or periodic list exports from Orbit.
- 3
BillionVerify verifies each email for DNS validity, SMTP reachability, disposable domain detection, and role-address patterns.
- 4
Results are returned with a status label (valid, invalid, catch-all, disposable, role-based).
- 5
Invalid members are flagged in Orbit or excluded from email-based outreach to protect your sender reputation.
When to use this
New member onboarding emails
Verify an email address the moment a new member is added to Orbit. Catch disposable or invalid addresses early so your welcome email reaches real community members and your onboarding metrics stay reliable.
Community digest delivery
Before sending weekly or monthly community digests, filter the recipient list through BillionVerify to remove addresses that have gone invalid since a member last engaged, reducing bounces and improving inbox placement.
FAQ
Why do community platform email lists degrade over time?
Members change jobs, abandon email accounts, or sign up with temporary addresses. Without periodic re-verification, your list accumulates undeliverable addresses that cause bounces and hurt deliverability.
Does verifying member emails affect their community access?
Verification only checks deliverability—it does not alter member permissions in Orbit. You decide what action to take based on the result.
Can I verify bulk member exports from Orbit?
Yes. Export your member list, submit it to BillionVerify's bulk verification endpoint, and reimport the results to tag or filter members in Orbit.
