Accurate, verified email addresses mean more revenue and sales when cleaning your account data. You need an email validationⓘ tool that provides the highest level of accuracy with a confidence guarantee.


ZeroBounce and UseBouncer are both excellent email validationⓘ tools that deliver a higher percentage of accurate results compared to most competitors. However, when validating bulk lists, especially as your business needs grow, every accuracy percentage can mean the difference between a valid and unknown result.
Furthermore, ZeroBounce provides users with an additional level of confidence through its guarantee. You can expect your email validationⓘ results to consistently deliver 99.6% accuracy while yielding fewer than 1% unknown or undetermined results. You'll also never spend money or credits on an address that cannot be validated.


In addition to accuracy, it's essential to know which types of email addresses your email validationⓘ tool can identify.
Valid & invalid
emails
Disposable
emails
Catch-all
emails
Spam
traps
While UseBouncer's results can provide effective validation that safeguards your email deliverabilityⓘ, ZeroBounce is capable of detecting more types of risky emails while providing additional insights into each contact you upload.
With ZeroBounce, you not only validate emails but can identify a wide array of email address types. Even if an address is valid, you'll know if a contact provided an alternate email, alias, or is a known spam complainer – all of which can have a negative impact on your email campaigns.
Even if you read otherwise - it's impossible to validate a catch-all email address.
Both ZeroBounce and UseBouncer feature catch-all domain detectionⓘ, which is helpful for avoiding bounces and other deliverability problems.
However, ZeroBounce provides Catch-all Scoring, which provides an additional score that indicates the likelihood that a real person is managing the inbox.
Finally, ZeroBounce provides a free email validationⓘ add-on known as Verify+ from ZeroBounceⓘ, which is currently the only technology capable of detecting email accounts that were disabled by mail providers like Yahoo and AOL.
With your permission, ZeroBounce checks for bounces by sending a message to the potentially disabled address. ZeroBounce handles the entire verification process and poses no risk to your company.
Both UseBouncer and ZeroBounce offer an easy-to-use email verification APIⓘ. This tool makes both email validationⓘ tools flexible so that you can easily incorporate them into your existing workflows, websites, and registration forms to check email addresses in real time.
