The short version

DeBounce competes on price, but independent reviews note slower processing, and catch-all validation is reported to cost 10 credits each. Email Verifier API is built for real-time speed and detects catch-all domains inside the standard one-credit check, flagging them as "unknown" rather than guessing, on credits that never expire with 100 free to start.

Built for speed.

Independent reviewers cite slow processing on DeBounce bulk jobs. Our 16-point engine is built for real-time use and returns a verdict in well under a second, whether you call the API or clean a list.

Honest catch-all handling, with no surcharge.

DeBounce is reported to charge 10 credits to attempt validation of a catch-all address. Because a catch-all domain accepts every address at the SMTP layer, that attempt can never be conclusive. We do not charge a premium for it: we detect catch-all domains as part of the standard one-credit check and flag them as "unknown" so you can decide how to handle them.

Compliance included.

Addresses are SHA-512 hashed and deleted within 30 days, so it is GDPR-friendly by default.
