Something to that affect. Unless I'm mistaken and all the verification solutions are pretty much the same.
I get a good amount of bounces from emails that Debounce says are valid, granted they are often catch-all give my market.
All SMTP verification providers are the same however some handle greylisting better which is important but still they’re all roughly the same. Enrichley’s native integration in Clay does both SMTP and catch all validation in one - typically get 20% more valid emails because of this.
