Tapfiliate email verification with BillionVerify
Tapfiliate is an affiliate marketing platform that lets businesses recruit, track, and pay affiliate partners. Partner and referral emails flow through the platform constantly, and a single bad address can break commission notifications or leave a top affiliate in the dark.
Why verify before the send
Affiliate relationships depend on reliable email delivery for commission alerts, payout confirmations, and program updates. BillionVerify filters out invalid, catch-all, and disposable addresses at the point of partner sign-up, protecting your sender reputation and keeping affiliates informed.

How it works
- 1

Trigger verification on new affiliate registration or before each payout email batch.
- 3
BillionVerify checks deliverability, identifies disposable email providers, and flags catch-all domains.

Maintain a clean affiliate list that supports strong email deliverability across all your Tapfiliate campaigns.
When to use this
Screen affiliates during onboarding
Verify every affiliate's email address before approving their account in Tapfiliate. This prevents fraudulent sign-ups using temporary email services and ensures real partners receive their commission notifications without issue.
Protect payout notification deliverability
Before triggering payout or performance emails, validate the recipient list with BillionVerify. Remove stale or invalid addresses that have accumulated over time to keep bounce rates low and email reputation strong.
FAQ
Why would affiliates use fake email addresses?
Some sign up with temporary or disposable addresses to claim referral bonuses without a long-term commitment. BillionVerify detects these domains instantly and flags them before approval.
Can I verify existing affiliates in bulk?
Yes. Export your current affiliate list, submit it to BillionVerify's bulk verification endpoint, and reimport only the records that pass — all without touching your Tapfiliate UI.
How does BillionVerify connect to Tapfiliate?
You can use the n8n community node or Integrately for a low-code integration, or hit the BillionVerify REST API from a webhook that fires when a new affiliate registers.
Does this work for sub-affiliate networks too?
Yes. Any email address entering your system — whether a top-level affiliate or a sub-affiliate — can be screened by BillionVerify before it is stored or messaged.
