How to Resell Email Verification Under Your Own Brand
How to resell email verification under your own brand on the BillionVerify API, on any plan and with no approval step. See who runs what, what the API gives you, what credits cost, and how the White Label tier changes the price.
Every Email Verification Result, Under Your Brand
Your white label email verification service returns the same results BillionVerify customers get, with your name on every screen. Each result type below also has a free checker page, so you can see how it works before you launch.
Free Email Checker
Your customers see which addresses use Gmail, Yahoo, Outlook.com, iCloud, or another free webmail provider instead of a company domain.
Email Spam Checker
Flags addresses on domains with a recorded spam, phishing, or malware history, so your customers keep risky contacts off their lists.
Disposable Email Detection
Catches temporary and throwaway domains before they reach the signup forms and mailing lists your customers protect.
Bounce Email Checker
Probes each mail server over SMTP so your customers remove addresses that would hard bounce before they send.
Catch-All Verifier
Marks domains that accept every address, so your customers know when an SMTP accept does not prove a real mailbox.
Role Account Detection
Identifies shared inboxes such as info@, support@, and sales@ that lower engagement in B2B email campaigns.
Who Runs a White Label Email Verification Service
Partners use white label email verification in three ways, and many combine more than one.
Your own email verification service
Sell email verification under your brand, at your prices, with your own dashboard on your own domain. The BillionVerify API runs the verification engine underneath, so you launch without building SMTP infrastructure.
Verification inside a bigger product
CRMs, lead generation tools, cold email platforms, and form builders add email verification as a feature their users pay for, without sending those users to another brand.
List cleaning for agency clients
Agencies clean client lists before every campaign and bill email list cleaning as their own service, with every screen and report carrying the agency brand.

How White Label Email Verification Works
- 1
Get an API key
Create an account on any plan. Every plan includes the email verification API and allows resale, so there is no separate white label approval to wait for.
- 2
Build under your brand
Put real-time, bulk, and file verification behind your own domain, dashboard, and pricing. Your customers only ever see your product.
- 3
Buy credits once
Buy a one-time credit pack. Above a set volume, the White Label tier gives our deepest discount, with no subscription and no 12-month commitment.
- 4
Sell and scale
Credits never expire, unknown results are free, and auto top-up keeps your customers' verification jobs running as you grow.
Why White Label Email Verification Pays
Email verification is a volume business, and your margin depends on what each verification costs you. BillionVerify's price per email is often a tenth or less of what services such as NeverBounce and ZeroBounce charge, which leaves room to price your white label service competitively and still earn on every list you verify.
Every BillionVerify plan includes the API and allows resale. The White Label tier only adds our deepest discount once a one-time credit purchase passes a set volume, with no subscription and no expiry date on the credits.
White Label Email Verification Guide
Open a topic for the details partners ask about most before they launch.
What your customers see
What your customers see
Your customers use your product on your own domain, with your logo and colours. Results come from the BillionVerify API and BillionVerify is never mentioned, so the email verification service reads as yours from the first check to the last report.
What the verification engine checks
What the verification engine checks
Each address goes through syntax validation, domain and MX record checks, and an SMTP mailbox probe. The engine also flags catch-all domains, disposable addresses, role accounts, free webmail, and spam-risk domains, and it marks a result as unknown when a mail server refuses to answer instead of guessing.
Features included in the White Label tier
Features included in the White Label tier
The same as every plan: the full email verification API with real-time single checks, bulk verification, and file uploads, and every result type. The White Label tier is the same product at our deepest discount on large one-time credit purchases.
White label vs building your own email verifier
White label vs building your own email verifier
Building an email verifier means running SMTP servers, keeping IP addresses in good standing, handling greylisting and rate limits, and keeping disposable and catch-all detection current. A white label email verification service gives you that infrastructure on day one, so your team spends its time on sales and customers.
White Label tier vs other plans
White Label tier vs other plans
There is no feature difference and no restriction on other plans. Any plan lets you resell BillionVerify and run the API behind your own SaaS. The White Label tier only changes the price: once a one-time credit purchase passes a set volume, you get our deepest discount.
No setup wait
No setup wait
You can start the day you sign up. Create an API key, connect it to your product, and start verifying; there is nothing for us to configure before your white label service goes live.
White label support and uptime

Frequently Asked Questions
1. What is white label email verification?
White label email verification means selling email verification under your own brand while another company runs the verification engine. With BillionVerify, you build your service on our API on any plan, and your customers never see our name. The White Label tier adds our deepest discount on large one-time credit purchases.
2. How long does white label setup take?
There is no setup wait. Every plan includes API access, so you can start building your white label email verification service as soon as you sign up. For the White Label discount, email our partnerships team with the credit volume you plan to buy.
3. Will my customers ever see the BillionVerify name?
No. You build the product your customers use on top of the BillionVerify API, so BillionVerify is not mentioned anywhere your customers look.
4. How do white label partners make money?
Most partners earn the difference between what they charge their customers and what each verification costs them. Because BillionVerify's price per email is often a tenth or less of what many email verification services charge, partners can price below well-known brands and still keep a healthy margin. Agencies also bundle email list cleaning into campaign retainers, and software companies charge for email verification as a paid feature.
5. Can I set my own prices for white label email verification?
Yes. You decide what your customers pay. You pay BillionVerify only for the credits you buy, and how you package and price email verification for your customers is up to you.
6. Can I resell BillionVerify without a white label plan?
Yes. Every BillionVerify plan includes the API and allows resale, so you can run email verification behind your own product and set your own prices. See email verification pricing for credit packs; the White Label tier only adds a deeper discount on large one-time credit purchases.
7. Which verification results do my customers get?
Every result type BillionVerify returns: valid and invalid addresses, catch-all domains, disposable addresses, role accounts, free webmail, and spam-risk domains, plus unknown when a mail server refuses to answer. Every result comes back through the API, so you can show it in your own dashboard and reports.
8. What do I need to launch a white label email verification service?
An account on any BillionVerify plan, an API key, and your own product or dashboard where your customers check emails. For the White Label discount, tell our partnerships team how many credits you plan to buy at once.
9. Is there a minimum white label commitment?
No. There is no 12-month commitment and no subscription. You buy credits once, they never expire, and you use them at your own pace.
10. Can I upgrade the white label plan later?
Yes. Buy more credits whenever you need them; larger one-time purchases unlock deeper discounts. Contact us to discuss higher volumes.
