Where Fidro differs from NeverBounce

More than the email

NeverBounce checks the email. Fidro checks the email, the IP, the network and the location in the same call, and remembers what it has seen before.

A decision, not a data point

Every call returns a score from 0 to 100 and allow, challenge or block, with the reasons. Your code acts on one field instead of building its own scoring.

Common questions

How does Fidro compare to NeverBounce for email validation?
NeverBounce verifies email addresses in real time, mainly to keep bounce rates down. Fidro checks the email too, but its job is fraud: it adds IP, VPN and location checks, remembers earlier signups from the same network, and returns a risk score with an allow, challenge or block recommendation.
Is Fidro cheaper than NeverBounce?
NeverBounce starts at $8 a month and offers 1,000 free credits. Fidro's free plan includes 200 validations a month, no credit card needed, and paid plans start at $29 a month for 5,000. If deliverability checks are all you need, NeverBounce is the cheaper fit.
Can I switch from NeverBounce to Fidro?
Yes. Fidro is one REST call, with SDKs for Node, PHP, Laravel, Python and Go, so switching from NeverBounce means changing the request and acting on the recommendation it returns. You also get IP, VPN and location checks in the same call. Blocklists come with the Starter plan, and Stripe payment scoring with Pro.
