Fintech use case
Verify emails at onboarding to reduce fraud and reach real inboxes
In fintech, the email a customer types at signup is both an identity signal and a lifeline for every statement, security alert, and reset link that follows. Verifly checks that address in real time during KYC and onboarding, flagging disposable domains, role inboxes, and undeliverable addresses that correlate with synthetic-identity fraud and broken transactional delivery.

Why email accuracy is a KYC and fraud problem, not just a marketing one
For most consumer products a bad email means a missed newsletter. For a fintech it means a customer who never receives a statement, a one-time passcode that bounces, or a fraud alert that never arrives. Worse, the pattern of email a user supplies at onboarding is itself a risk signal. Fraud rings assembling synthetic identities lean heavily on disposable and freshly minted throwaway domains because they need addresses that survive just long enough to clear signup and drain a promotion.
Verifly gives you that signal at the moment it matters. A real-time check at account creation tells you whether the address is deliverable, whether the domain is a known disposable provider, whether it is a role inbox that a genuine consumer would rarely use, and whether the domain is catch-all and therefore accepts anything. Feeding those flags into your KYC decisioning lets you route the highest-risk signups to step-up verification instead of discovering the problem after money has moved.
Protecting transactional deliverability and compliance mail
Regulated fintechs are obligated to deliver certain communications: privacy notices, adverse-action letters, statements, and account-change confirmations. When those messages bounce, you are not just annoying a customer, you may be failing a compliance requirement and simultaneously teaching mailbox providers that your sending domain mails bad addresses. That reputational damage then degrades delivery of the security-critical mail your good customers depend on.
Verifly returns a clear deliverable, undeliverable, or risky verdict so you can reject or correct a typo at the point of entry rather than absorbing the bounce later. For an existing book of business, run the whole customer table through the async bulk endpoint to find addresses that have gone stale before your next required mailing.

- Call GET /verify?email= inline on the signup form to block obvious typos and disposables.
- Pass the disposable, role, and catch-all flags into your KYC risk model for step-up routing.
- Periodically POST /verify/batch or run the async bulk job against your customer table to catch decay.

Frequently asked questions
Does Verifly do KYC or identity verification?
No. Verifly verifies email deliverability and returns risk flags on the address itself — disposable, role, catch-all, deliverable or not. It is not a KYC provider and does not check identity documents. Fintechs use it as one signal inside a broader KYC and fraud-decisioning stack, not as a replacement for it.
How does email verification help catch synthetic-identity fraud?
Synthetic and bulk-fraud signups disproportionately use disposable, throwaway, and freshly registered domains because the address only needs to survive signup. Verifly flags disposable domains and undeliverable addresses in real time, letting you route those applications to step-up verification instead of approving them automatically.
Can I verify emails inline during account creation?
Yes. A single GET /verify?email= call returns in real time, so you can validate the address on the signup form before the account is created, block obvious typos and disposables, and keep clean data out of your KYC pipeline.
Why does deliverability matter for compliance mail?
Regulated communications like statements, privacy notices, and adverse-action letters must actually reach the customer. Bounced compliance mail is both a regulatory gap and a reputation hit that degrades delivery of security-critical messages. Verifying addresses up front keeps those obligations deliverable.
Can I re-check my existing customer base?
Yes. Submit your full customer table to the async bulk endpoint (up to 1,000,000 addresses per job) to find addresses that have gone stale, so a required mailing does not bounce months after onboarding.
What does Verifly cost for a fintech at scale?
Pricing is pay-as-you-go, starting at $2 per 1,000 verifications and dropping to $0.60 per 1,000 at the largest pack. Credits do not expire, so seasonal onboarding spikes do not require a fixed monthly subscription.
