Email verification
Ensure every email address you collect is genuine and able to receive messages.
Verify addresses in real-time at point of capture, or clean your existing lists in bulk.
What is email verification?
Email verification is the process of checking if an email is real, active and able to receive email messages
Inaccurate email addresses compound over time. Typos, outdated contacts and role-based emails bloat your database, increasing send costs, distorting reporting and creating avoidable friction.
Verify email addresses to:
Reduce failed deliveries and hard bounces
Protect your sender reputation and deliverability
Keep your CRM clean, accurate and actionable
Eliminate CRM spend for uncontactable records
Maintain ongoing data hygiene and compliance

Ways to use our service
More than a pass or fail
Every verification returns a deliverability determination you can act on
Our deliverability assessment gives you a richer picture of each address, so you can make smarter decisions about how to use your data rather than applying a blanket rule.
Whether you're cleaning a list before a campaign, filtering signups at the point of capture, or segmenting a database for re-engagement, we give you as much information as possible to make informed decisions with each email address.
Customise what data to accept
As part of Addressfinder's email verification, we provide additional information on each email's attributes.
You can configure allow, warn, or block rules for the below attributes, giving you full control over data quality without compromising conversion.
Configurable attributes
Disposable: temporary or throwaway addresses
Role-based: shared inboxes such as support@ or info@
Public: emails from providers like Gmail or Yahoo
Unverified: emails that don’t pass our verification checks
