Fintech lead verification
Fintech companies face an unusual data-quality constraint: regulatory onboarding processes collect highly accurate contact information at the time of KYC, but that data drifts fast as users change jobs, switch email providers, or update personal phones without notifying the platform. The delta between onboarding accuracy and campaign accuracy widens every quarter. For B2B fintech targeting CFOs and finance teams, the additional problem is that role-based inboxes often gate access to senior contacts who are the actual decision-makers.
What's hiding in your list
User email addresses captured during KYC onboarding are often personal addresses that become inactive when users prefer to consolidate to a new provider, creating silent delivery failures on transactional and marketing sends.
B2B fintech outreach lists sourced from industry databases contain a high proportion of generic finance-team inboxes (accounts@, finance@) that route to shared queues rather than individual decision-makers.
Referral and affiliate-driven acquisition introduces contacts with incentive-motivated sign-ups, including temporary or forwarded email addresses unlikely to convert to paying accounts.

Frequently asked
We send both transactional and marketing emails from the same domain. Can bad addresses on our marketing list hurt our transactional deliverability?
Yes — domain reputation is shared across all send streams. Hard bounces from stale marketing contacts lower your domain reputation score with ISPs, which can delay or filter even password-reset and payment-confirmation emails. Cleaning your marketing list protects transactional deliverability as a side effect.
We target finance leaders at mid-market companies. How do we know if the company record is still accurate?
BounceBlock includes company data enrichment so you can verify that the organisation still operates at the domain and sector you expect, which matters when targeting by company size or industry vertical — a company that has pivoted or been acquired may no longer fit your ICP.
Our compliance team is concerned about retaining contact data. What is your data handling policy?
BounceBlock deletes uploaded data within 24 hours of processing and is designed to be GDPR-friendly, which addresses the core concern most fintech compliance teams raise about third-party data processing. The free 100-row preview at signup also lets you test the output before submitting a full list.
