Helpful Support for Catch-All Interpretation and Segmentation
Support was actually helpful when we asked about interpretation of catch-all results, and their guidance improved how we segment follow-ups rather than deleting everything questionable

Real-Time Signup Gate That Catches Typos
We run it as a final gate in our signup flow, and the real-time verification catches typos like gmial.com and hotnail.com so support isn’t chasing missing confirmations later

The UI is straightforward and doesn’t bury settings, and the duplicate detection plus formatting cleanup saved us time before uploading lists into Mailchimp

Disposable and Toxic Domain Flags That Protect Deliverability
I like that it flags disposable and toxic domains separately, because those are the ones that always wreck deliverability for us during promo sends

Fast Batch Verification + Sheets-Ready Exports
The batch verification is fast and the export format plays nicely with Google Sheets, plus the “unknown” outcomes are explained well enough that my team knows what to do next

Developer-Friendly API With Actionable Detail
The API was easy to wire into our backend (docs are clear, responses are predictable), and the results include enough detail to make routing decisions instead of just “valid/invalid”
